+# BH1750 usermod
+
+This usermod will read from an ambient light sensor like the BH1750 sensor.
+The luminance is displayed both in the Info section of the web UI as well as published to the `/luminance` MQTT topic if enabled.
+
+## Installation
+
+Copy the example `platformio_override.ini` to the root directory.  This file should be placed in the same directory as `platformio.ini`.
+
+### Define Your Options
+
+*   `USERMOD_BH1750`                                - define this to have this user mod included wled00\usermods_list.cpp
+*   `USERMOD_BH1750_MAX_MEASUREMENT_INTERVAL`       - the max number of milliseconds between measurements, defaults to 10000ms
+*   `USERMOD_BH1750_MIN_MEASUREMENT_INTERVAL`       - the min number of milliseconds between measurements, defaults to 500ms
+*   `USERMOD_BH1750_FIRST_MEASUREMENT_AT`           - the number of milliseconds after boot to take first measurement, defaults to 10 seconds
+*   `USERMOD_BH1750_OFFSET_VALUE`                   - the offset value to report on, defaults to 1
+
+All parameters can be configured at runtime using Usermods settings page.
+
+### PlatformIO requirements
+
+If you are using `platformio_override.ini`, you should be able to refresh the task list and see your custom task, for example `env:usermod_BH1750_d1_mini`.

+     * addToConfig() will make your settings editable through the Usermod Settings page automatically.

+     * Usermod Settings Overview:
+     * - Numeric values are treated as floats in the browser.
+     *   - If the numeric value entered into the browser contains a decimal point, it will be parsed as a C float
+     *     before being returned to the Usermod.  The float data type has only 6-7 decimal digits of precision, and
+     *     doubles are not supported, numbers will be rounded to the nearest float value when being parsed.
+     *     The range accepted by the input field is +/- 1.175494351e-38 to +/- 3.402823466e+38.
+     *   - If the numeric value entered into the browser doesn't contain a decimal point, it will be parsed as a
+     *     C int32_t (range: -2147483648 to 2147483647) before being returned to the usermod.
+     *     Overflows or underflows are truncated to the max/min value for an int32_t, and again truncated to the type
+     *     used in the Usermod when reading the value from ArduinoJson.
+     * - Pin values can be treated differently from an integer value by using the key name "pin"
+     *   - "pin" can contain a single or array of integer values
+     *   - On the Usermod Settings page there is simple checking for pin conflicts and warnings for special pins
+     *     - Red color indicates a conflict.  Yellow color indicates a pin with a warning (e.g. an input-only pin)
+     *   - Tip: use int8_t to store the pin value in the Usermod, so a -1 value (pin not set) can be used
+     *
+     * See usermod_v2_auto_save.h for an example that saves Flash space by reusing ArduinoJson key name strings
+     * 
+     * If you need a dedicated settings page with custom layout for your Usermod, that takes a lot more work.  
+     * You will have to add the setting to the HTML, xml.cpp and set.cpp manually.
+     * See the WLED Soundreactive fork (code and wiki) for reference.  https://github.com/atuline/WLED
      * 
      * I highly recommend checking out the basics of ArduinoJson serialization and deserialization in order to use custom settings!

+# JSON IR remote
+
+## Purpose 
+
+The JSON IR remote allows users to customize IR remote behavior without writing custom code and compiling. 
+It also enables using any remote that is compatible with your IR receiver. Using the JSON IR remote, you can
+map buttons from any remote to any HTTP request API or JSON API command.  
+
+## Usage
+
+* Upload the IR config file, named _ir.json_ to your board using the [ip address]/edit url. Pick from one of the included files or create your own.
+* On the config > LED settings page, set the correct IR pin.
+* On the config > Sync Interfaces page, select "JSON Remote" as the Infrared remote.
+
+## Modification
+
+* See if there is a json file with the same number of buttons as your remote. Many remotes will have the same internals and emit the same codes but have different labels.
+* In the ir.json file, each key will be the hex encoded IR code.
+* The "cmd" property will be the HTTP Request API or JSON API to execute when that button is pressed.
+* A limited number of c functions are supported (!incBrightness, !decBrightness, !presetFallback)
+* When using !presetFallback, include properties PL (preset to load), FX (effect to fall back to) and FP (palette to fall back to)
+* If the command is _repeatable_ and does not contain the "~" character, add a "rpt": true property.
+* Other properties are ignored, but having a label property may help when editing.
+
+
+Sample:
+{
+  "0xFF629D": {"cmd": "T=2", "rpt": true, "label": "Toggle on/off"},  // HTTP command
+  "0xFF9867": {"cmd": "A=~16", "label": "Inc brightness"},            // HTTP command with incrementing          
+  "0xFF38C7": {"cmd": {"bri": 10}, "label": "Dim to 10"},             // JSON command 
+  "0xFF22DD": {"cmd": "!presetFallback", "PL": 1, "FX": 16, "FP": 6,  
+               "label": "Preset 1 or fallback to Saw - Party"},       // c function
+}

+# PWM fan
+
+v2 Usermod to to control PWM fan with RPM feedback and temperature control
+
+This usermod requires Dallas Temperature usermod to obtain temperature information. If this is not available the fan will always run at 100% speed.
+If the fan does not have _tacho_ (RPM) output you can set the _tacho-pin_ to -1 to not use that feature.
+
+You can also set the thershold temperature at which fan runs at lowest speed. If the actual temperature measured will be 3°C greater than threshold temperature the fan will run at 100%.
+
+If the _tacho_ is supported the current speed (in RPM) will be repored in WLED Info page.
+
+## Installation
+
+Add the compile-time option `-D USERMOD_PWM_FAN` to your `platformio.ini` (or `platformio_override.ini`) or use `#define USERMOD_PWM_FAN` in `myconfig.h`.
+You will also need `-D USERMOD_DALLASTEMPERATURE`.
+
+### Define Your Options
+
+All of the parameters are configured during run-time using Usermods settings page.
+This includes:
+
+* PWM output pin
+* tacho input pin
+* sampling frequency in seconds
+* threshold temperature in degees C
+
+_NOTE:_ You may also need to tweak Dallas Temperature usermod sampling frequency to match PWM fan sampling frequency.
+
+### PlatformIO requirements
+
+No special requirements.
+
+## Change Log
+
+2021-10

+# ST7789 TFT IPS Color display 240x240pxwith ESP32 boards
+
+This usermod allow to use 240x240 display to display following:
+
+* Network SSID;
+* IP address;
+* Brightness;
+* Chosen effect;
+* Chosen palette;
+* Estimated current in mA;
+
+## Hardware
+
+***
+![Hardware](images/ST7789_guide.jpg)
+
+## Library used
+
+[Bodmer/TFT_eSPI](https://github.com/Bodmer/TFT_eSPI)
+
+## Setup
+
+***
+
+### Platformio.ini changes
+
+In the `platformio.ini` file, uncomment the `TFT_eSPI` line within the [common] section, under `lib_deps`:
+
+```ini
+# platformio.ini
+...
+[common]
+...
+lib_deps =
+    ...
+  #For use of the TTGO T-Display ESP32 Module with integrated TFT display uncomment the following line  
+    #TFT_eSPI
+...
+```
+
+Also, while in the `platformio.ini` file, you must change the environment setup to build for just the esp32dev platform as follows:
+
+Add lines to section:
+
+```ini
+default_envs = esp32dev
+build_flags = ${common.build_flags_esp32}
+  -D USERMOD_ST7789_DISPLAY
+
+```
+
+Save the `platformio.ini` file.  Once this is saved, the required library files should be automatically downloaded for modifications in a later step.
+
+### TFT_eSPI Library Adjustments
+
+We need to modify a file in the `TFT_eSPI` library. If you followed the directions to modify and save the `platformio.ini` file above, the `User_Setup_Select.h` file can be found in the `/.pio/libdeps/esp32dev/TFT_eSPI` folder.
+
+Modify the  `User_Setup_Select.h` file as follows:
+
+* Comment out the following line (which is the 'default' setup file):
+
+```ini
+//#include <User_Setup.h>           // Default setup is root library folder
+```
+
+* Add following line:
+
+```ini
+#include <User_Setups/Setup_ST7789_Display.h>    // Setup file for ESP32 ST7789V SPI bus TFT
+```
+
+* Copy file `"Setup_ST7789_Display.h"` from usermod folder to `/.pio/libdeps/esp32dev/TFT_eSPI/User_Setups`

+# :battery: Battery status/level Usermod :battery:
+
+This Usermod allows you to monitor the battery level of your battery powered project.
+
+You can see the battery level and voltage in the `info modal`. 
+
+For this to work the positive side of the (18650) battery must be connected to pin `A0` of the d1mini/esp8266 with a 100k ohm resistor (see [Useful Links](#useful-links)).
+
+If you have a esp32 board it is best to connect the positive side of the battery to ADC1 (GPIO32 - GPIO39)

+
+## Installation
+
+define `USERMOD_BATTERY_STATUS_BASIC` in `my_config.h`
+
+### Basic wiring diagram
+<p align="center">
+  <img width="300" src="assets/battery_connection_schematic_01.png">
+</p>
+
+### Define Your Options
+
+* `USERMOD_BATTERY_STATUS_BASIC`                   - define this (in `my_config.h`) to have this user mod included wled00\usermods_list.cpp
+* `USERMOD_BATTERY_MEASUREMENT_PIN`                - defaults to A0 on esp8266 and GPIO32 on esp32
+* `USERMOD_BATTERY_MEASUREMENT_INTERVAL`           - the frequency to check the battery, defaults to 30 seconds
+* `USERMOD_BATTERY_MIN_VOLTAGE`                    - minimum voltage of the Battery used, default is 2.6 (18650 battery standard)
+* `USERMOD_BATTERY_MAX_VOLTAGE`                    - maximum voltage of the Battery used, default is 4.2 (18650 battery standard)
+
+All parameters can be configured at runtime using Usermods settings page.
+
+## Important :warning:
+* Make sure you know your battery specification ! not every battery is the same !

+     * If you want to force saving the current state, use serializeConfig() in your loop().
+     * 
+     * CAUTION: serializeConfig() will initiate a filesystem write operation.
+     * It might cause the LEDs to stutter and will cause flash wear if called too often.
+     * Use it sparingly and always in the loop, never in network callbacks!
+     * 
+     * addToConfig() will make your settings editable through the Usermod Settings page automatically.
+     *
+     * Usermod Settings Overview:
+     * - Numeric values are treated as floats in the browser.
+     *   - If the numeric value entered into the browser contains a decimal point, it will be parsed as a C float
+     *     before being returned to the Usermod.  The float data type has only 6-7 decimal digits of precision, and
+     *     doubles are not supported, numbers will be rounded to the nearest float value when being parsed.
+     *     The range accepted by the input field is +/- 1.175494351e-38 to +/- 3.402823466e+38.
+     *   - If the numeric value entered into the browser doesn't contain a decimal point, it will be parsed as a
+     *     C int32_t (range: -2147483648 to 2147483647) before being returned to the usermod.
+     *     Overflows or underflows are truncated to the max/min value for an int32_t, and again truncated to the type
+     *     used in the Usermod when reading the value from ArduinoJson.
+     * - Pin values can be treated differently from an integer value by using the key name "pin"
+     *   - "pin" can contain a single or array of integer values
+     *   - On the Usermod Settings page there is simple checking for pin conflicts and warnings for special pins
+     *     - Red color indicates a conflict.  Yellow color indicates a pin with a warning (e.g. an input-only pin)
+     *   - Tip: use int8_t to store the pin value in the Usermod, so a -1 value (pin not set) can be used
+     *
+     * See usermod_v2_auto_save.h for an example that saves Flash space by reusing ArduinoJson key name strings
+     * 
+     * If you need a dedicated settings page with custom layout for your Usermod, that takes a lot more work.  
+     * You will have to add the setting to the HTML, xml.cpp and set.cpp manually.
+     * See the WLED Soundreactive fork (code and wiki) for reference.  https://github.com/atuline/WLED
+     * 
+     * I highly recommend checking out the basics of ArduinoJson serialization and deserialization in order to use custom settings!

+# QuinLED-An-Penta
+The (un)official usermod to get the best out of the QuinLED-An-Penta, like using the OLED and the SHT30 temperature/humidity sensor.
+
+## Requirements
+* "u8gs" by olikraus, v2.28 or higher: https://github.com/olikraus/u8g2
+* "SHT85" by Rob Tillaart, v0.2 or higher: https://github.com/RobTillaart/SHT85
+
+## Usermod installation
+Simply copy the below block (build task) to your `platformio_override.ini` and compile WLED using this new build task. Or use an existing one and add the buildflag `-D QUINLED_AN_PENTA`.
+
+ESP32 (**without** ethernet):
+```
+[env:custom_esp32dev_usermod_quinled_an_penta]
+extends = env:esp32dev

+
+## Some words about the (optional) OLED
+This mod has been optimized for an SSD1306 driven 128x64 OLED. Using a smaller OLED or an OLED using a different driver will result in unexpected results.
+I highly recommend using these "two color monochromatic OLEDs", which have the first 16 pixels in a different color than the other 48, e.g. a yellow/blue OLED.
+Also note, you need to have an **SPI** driven OLED, **not i2c**!
+
+### My OLED flickers after some time, what should I do?
+That's a tricky one: During development I saw that the OLED sometimes starts to "bug out" / flicker and won't work anymore. This seems to be caused by the high PWM interference the board produces. It seems to loose it's settings and then doesn't know how to draw anymore. Turns out the only way to fix this is to call the libraries `begin()` method again which will re-initialize the display.
+If you're facing this issue, you can enable a setting I've added which will call the `begin()` roughly every 60 seconds between a page change. This will make the page change take ~500ms, but will fix the display.
+
+## Configuration
+Navigate to the "Config" and then to the "Usermods" section. If you compiled WLED with `-D QUINLED_AN_PENTA`, you will see the config for it there:
+* Enable-OLED:
+  * What it does: Enabled the optional SPI driven OLED that can be mounted to the 7-pin female header
+  * Possible values: Enabled/Disabled
+  * Default: Disabled
+* OLED-Use-Progress-Bars:
+  * What it does: Toggle between showing percentage numbers or a progress-bar-like visualization for overall brightness and each LED channels brightness level
+  * Possible values: Enabled/Disabled
+  * Default: Disabled
+* OLED-Flip-Screen-180:
+  * What it does: Flips the screen 180° / upside-down
+  * Possible values: Enabled/Disabled
+  * Default: Disabled
+* OLED-Seconds-Per-Page:
+  * What it does: Defines how long the OLED should stay on one page in seconds before changing to the next
+  * Possible values: Enabled/Disabled
+  * Default: 10
+* OLED-Fix-Bugged-Screen:
+  * What it does: Enable this if your OLED flickers after some time. For more info read above under ["My OLED flickers after some time, what should I do?"](#My-OLED-flickers-after-some-time-what-should-I-do)
+  * Possible values: Enabled/Disabled
+  * Default: Disabled
+* Enable-SHT30-Temp-Humidity-Sensor:
+  * What it does: Enabled the onboard SHT30 temperature and humidity sensor
+  * Possible values: Enabled/Disabled
+  * Default: Disabled

+# RGB Encoder Board
+
+This usermod-v2 adds support for the awesome RGB Rotary Encoder Board by Adam Zeloof / "Isotope Engineering" to control the overall brightness of your WLED instance: https://github.com/isotope-engineering/RGB-Encoder-Board. A great DIY rotary encoder with 20 tiny SK6805 / "NeoPixel Nano" LEDs.
+
+https://user-images.githubusercontent.com/3090131/124680599-0180ab80-dec7-11eb-9065-a6d08ebe0287.mp4
+
+## Credits
+The actual / original code that does the different LED modes is from Adam Zeloof. So I don't take credit for these. But I ported it to WLED, which involved replacing the LED library he used (because, guess what, WLED already has one; so no need to add another one, but use whatever WLED uses), plus the rotary encoder library, because that one was not compatible with ESP, only Arduino.
+So it was quite more work than I hoped, but I got there eventually :)
+
+## Requirements
+* "ESP Rotary" by Lennart Hennigs, v1.5.0 or higher: https://github.com/LennartHennigs/ESPRotary
+
+## Usermod installation
+Simply copy the below block (build task) to your `platformio_override.ini` and compile WLED using this new build task. Or use an existing one and add the buildflag `-D RGB_ROTARY_ENCODER`.
+
+ESP32:
+```
+[env:custom_esp32dev_usermod_rgb_encoder_board]
+extends = env:esp32dev
+build_flags = ${common.build_flags_esp32} -D WLED_RELEASE_NAME=ESP32 -D RGB_ROTARY_ENCODER
+lib_deps = ${esp32.lib_deps}
+    lennarthennigs/ESP Rotary@^1.5.0
+```
+
+ESP8266 / D1 Mini:
+```
+[env:custom_d1_mini_usermod_rgb_encoder_board]
+extends = env:d1_mini
+build_flags = ${common.build_flags_esp8266} -D RGB_ROTARY_ENCODER
+lib_deps = ${esp8266.lib_deps}
+    lennarthennigs/ESP Rotary@^1.5.0
+```
+
+## How to connect the board to your ESP
+We gonna need (minimum) three or (maximum) four GPIOs for the board:
+* "ea": Basically tells if the encoder goes into one or the other direction
+* "eb": Same thing, but the other direction
+* "di": LED data in. To actually control the LEDs
+* *(optional)* "sw": The integrated switch in the rotary encoder. Can be omitted for the bare functionality of just controlling the brightness
+
+We also gonna need some power, so:
+
+* "vdd": Needs to be connected to **+5V**.
+* "gnd": Well, it's GND.
+
+You can freely pick the GPIOs, it doesn't matter. Those will be configured in the "Usermods" section in the WLED web panel:
+
+## Configuration
+Navigate to the "Config" and then to the "Usermods" section. If you compiled WLED with `-D RGB_ROTARY_ENCODER`, you will see the config for it there. The settings there are the GPIOs we mentioned before (*Note: The switch pin is not there, as this can just be configured the "normal" button on the "LED Preferences" page*), plus a few more:
+* LED pin:
+  * Possible values: Any valid and available GPIO
+  * Default: 3
+  * What it does: Pin to control the LED ring
+* ea pin:
+  * Possible values: Any valid and available GPIO
+  * Default: 15
+  * What it does: First of the two rotary encoder pins
+* eb pin:
+  * Possible values: Any valid and available GPIO
+  * Default: 32
+  * What it does: Second of the two rotary encoder pins
+* LED Mode:
+  * Possible values: 1-3
+  * Default: 3
+  * What it does: The usermod provides three different modes of how the LEDs can look like. Here's an example: https://github.com/isotope-engineering/RGB-Encoder-Board/blob/master/images/rgb-encoder-animations.gif
+    * Up left is "1"
+    * Up right is not supported / doesn't make sense for brightness control
+    * Bottom left is "2"
+    * Bottom right is "3"
+* LED Brightness:
+  * Possible values: 1-255
+  * Default: 64
+  * What it does: Brightness of the LED ring
+* Steps per click:
+  * Possible values: Any positive number
+  * Default: 4
+  * What it does: With each "click", a rotary encoder actually increments it's "steps". Most rotary encoder do four "steps" per "click". I know this sounds super weird, so just leave this the default value, unless your rotary encoder behaves weirdly, like with one click, it makes two LEDs light up, or you sometimes need two click for one LED. Then you should play around with this value or write a small sketch using the same "ESP Rotary" library and read out the steps it does.
+* Increment per click:
+  * Possible values: Any positive number
+  * Default: 5
+  * What it does: Most rotary encoder have 20 "clicks", so basically 20 positions. This value should be set to 100 / `number of clicks`

+
+Usermod that uses the overlay feature to create a configurable seven segment display.  
+This has only been tested on a single configuration. Colon support is entirely  untested. 
+
+## Installation
+
+Add the compile-time option `-D USERMOD_SEVEN_SEGMENT` to your `platformio.ini` (or `platformio_override.ini`) or use `#define USERMOD_SEVEN_SEGMENT` in `my_config.h`.
+
+## Settings
+Settings can be controlled through both the usermod setting page and through MQTT with a raw payload.
+##### Example
+ Topic ```<mqttDeviceTopic||mqttGroupTopic>/sevenSeg/perSegment/set```  
+ Payload ```3```
+#### perSegment -- ssLEDPerSegment
+The number of individual LEDs per segment. There are 7 segments per digit.  
+#### perPeriod -- ssLEDPerPeriod
+The number of individual LEDs per period. A ':' has 2x periods.
+#### startIdx -- ssStartLED
+Index of the LED that the display starts at. Allows a seven segment display to be in the middle of a string.
+#### timeEnable -- ssTimeEnabled
+When true, when displayMask is configured for a time output and no message is set the time will  be displayed.
+#### scrollSpd -- ssScrollSpeed
+Time, in milliseconds, between message shifts when the length of displayMsg exceeds the length of the displayMask.
+#### displayMask -- ssDisplayMask
+This should represent the configuration of the physical display. 
+<pre>
+HH - 0-23. hh - 1-12, kk - 1-24 hours  
+MM or mm - 0-59 minutes  
+SS or ss = 0-59 seconds  
+: for a colon  
+All others for alpha numeric, (will be blank when displaying time)
+</pre>
+##### Example
+```HHMMSS ```  
+```hh:MM:SS ```
+#### displayMsg -- ssDisplayMessage
+Message to be displayed across the display. If the length exceeds the length of the displayMask the message will scroll at scrollSpd. To 'remove' a message or revert  back to time, if timeEnabled is true, set the message to '~'.
+#### displayCfg -- ssDisplayConfig
+The order that your LEDs are configured. All seven segments in the display need to be wired the same way.

+# Rotary Encoder (Brightness and Color)
+
+V2 usermod that allows changing brightness and color using a rotary encoder, 
+change between modes by pressing a button (many encoders have one included)
+
+but it will wait for AUTOSAVE_SETTLE_MS milliseconds, a "settle" 
+period in case there are other changes (any change will 
+extend the "settle" window).
+
+It will additionally load preset AUTOSAVE_PRESET_NUM at startup.
+during the first `loop()`.  Reasoning below.
+
+AutoSaveUsermod is standalone, but if FourLineDisplayUsermod is installed, it will notify the user of the saved changes.
+
+Note: I don't love that WLED doesn't respect the brightness of the preset being auto loaded, so the AutoSaveUsermod will set the AUTOSAVE_PRESET_NUM preset in the first loop, so brightness IS honored. This means WLED will effectively ignore Default brightness and Apply N preset at boot when the AutoSaveUsermod is installed.
+
+## Installation
+
+define `USERMOD_ROTARY_ENCODER_BRIGHTNESS_COLOR` e.g.
+
+`#define USERMOD_ROTARY_ENCODER_BRIGHTNESS_COLOR` in my_config.h
+
+or add `-D USERMOD_ROTARY_ENCODER_BRIGHTNESS_COLOR` to `build_flags` in platformio_override.ini
+
+### Define Your Options
+
+Open Usermod Settings in WLED to change settings:
+
+`fadeAmount` - how many points to fade the Neopixel with each step of the rotary encoder (default 5)
+`pin[3]` - pins to connect to the rotary encoder:
+- `pin[0]` is pin A on your rotary encoder
+- `pin[1]` is pin B on your rotary encoder
+- `pin[2]` is the button on your rotary encoder (optional, set to -1 to disable the button and the rotary encoder will control brightness only)
+
+### PlatformIO requirements
+
+No special requirements.
+
+## Change Log
+
+2021-07
+* Upgraded to work with the latest WLED code, and make settings configurable in Usermod Settings

+# I2C 4 Line Display Usermod ALT
+
+Thank you to the authors of the original version of these usermods. It would not have been possible without them!
+"usermod_v2_four_line_display"
+"usermod_v2_rotary_encoder_ui"
+
+The core of these usermods are a copy of the originals. The main changes are done to the FourLineDisplay usermod.
+The display usermod UI has been completely changed.
+
+
+The changes made to the RotaryEncoder usermod were made to support the new UI in the display usermod. 
+Without the display it functions identical to the original.
+The original "usermod_v2_auto_save" will not work with the display just yet.
+
+Press the encoder to cycle through the options:
+    *Brightness
+    *Speed
+    *Intensity
+    *Palette
+    *Effect
+    *Main Color (only if display is used)
+    *Saturation (only if display is used)
+
+Press and hold the encoder to display Network Info
+    if AP is active then it will display AP ssid and Password
+
+Also shows if the timer is enabled
+
+[See the pair of usermods in action](https://www.youtube.com/watch?v=ulZnBt9z3TI)
+
+## Installation
+
+Please refer to the original `usermod_v2_rotary_encoder_ui` readme for the main instructions
+Then to activate this alternative usermod add `#define USE_ALT_DISPlAY` to the `usermods_list.cpp` file,
+                                        or add `-D USE_ALT_DISPlAY` to the original `platformio_override.ini.sample` file
+
+
+### PlatformIO requirements
+
+Note: the Four Line Display usermod requires the libraries `U8g2` and `Wire`.

+# Rotary Encoder UI Usermod ALT
+
+Thank you to the authors of the original version of these usermods. It would not have been possible without them!
+"usermod_v2_four_line_display"
+"usermod_v2_rotary_encoder_ui"
+
+The core of these usermods are a copy of the originals. The main changes are done to the FourLineDisplay usermod.
+The display usermod UI has been completely changed.
+
+
+The changes made to the RotaryEncoder usermod were made to support the new UI in the display usermod. 
+Without the display it functions identical to the original.
+The original "usermod_v2_auto_save" will not work with the display just yet.
+
+Press the encoder to cycle through the options:
+    *Brightness
+    *Speed
+    *Intensity
+    *Palette
+    *Effect
+    *Main Color (only if display is used)
+    *Saturation (only if display is used)
+
+Press and hold the encoder to display Network Info
+    if AP is active then it will display AP ssid and Password
+
+Also shows if the timer is enabled
+
+[See the pair of usermods in action](https://www.youtube.com/watch?v=ulZnBt9z3TI)
+
+## Installation
+
+Please refer to the original `usermod_v2_rotary_encoder_ui` readme for the main instructions
+Then to activate this alternative usermod add `#define USE_ALT_DISPlAY` to the `usermods_list.cpp` file,
+                                        or add `-D USE_ALT_DISPlAY` to the original `platformio_override.ini.sample` file
+
+
+### PlatformIO requirements
+
+Note: the Four Line Display usermod requires the libraries `U8g2` and `Wire`.
+
+## Change Log

+// Inspired by the original v2 usermods
+// * usermod_v2_rotaty_encoder_ui
+//
+// v2 usermod that provides a rotary encoder-based UI.
+//
+// This usermod allows you to control:
+// 
+// * Brightness
+// * Selected Effect
+// * Effect Speed
+// * Effect Intensity
+// * Palette
+//
+// Change between modes by pressing a button.
+//
+// Dependencies
+// * This usermod REQURES the ModeSortUsermod
+// * This Usermod works best coupled with 
+//   FourLineDisplayUsermod.
+//
+// If FourLineDisplayUsermod is used the folowing options are also inabled
+//
+// * main color
+// * saturation of main color
+// * display network (long press buttion)
