 ## Recommended ESP32 devices
 
-We don't recommend using single-core ESP32 devices (ESP32-C3, ESP32-C6, ESP32-H2, ESP32-Solo1).<br>
+We don't recommend using the original ESP32 or ESP32-Solo1 devices because these devices experience unexpected crashes related to the (closed-source) BLE controller.<br>
-Although Nuki Hub supports single-core devices, Nuki Hub uses both CPU cores (if available) to process tasks (e.g. HTTP server/MQTT client/BLE scanner/BLE client) and thus runs much better on dual-core devices.<br>
+In newer models (e.g. ESP32-S3, ESP32-P4, ESP32-C3, ESP32-C5, ESP32-C6, ESP32-H2) these unexpected crashed are seen a lot less.
 
-We also don't recommend using the original ESP32 or ESP32-Solo1 devices because these devices experience unexpected crashes related to the (closed-source) BLE controller.<br>

 The ESP32-S3 is a dual-core CPU with many GPIO's, ability to enlarge RAM using PSRAM, ability to connect Ethernet modules over SPI and optionally power the device with a PoE splitter.<br>
-The only functions missing from the ESP32-S3 as compared to other ESP devices is the ability to use some Ethernet modules only supported by the original ESP32 (and ESP32-P4) and the ability to connect over WIFI6 (C6 or ESP32-P4 with C6 module)
+The only functions missing from the ESP32-S3 as compared to other ESP devices is the ability to use some Ethernet modules only supported by the original ESP32 (and ESP32-P4) and the ability to connect over WIFI6 (C5, C6 or ESP32-P4 with C6 module)
+
+The ESP32-C5 with PSRAM is a good option providing higher clockspeeds than the C6 and adding PSRAM and WIFI 6 on the 5 Ghz band support.
+Nuki Hub uses both CPU cores (if available) to process tasks (e.g. HTTP server/MQTT client/BLE scanner/BLE client) and thus runs better on dual-core devices.<br>
 
 We provide a build for the ESP32-P4 with ESP32-C6-MINI-1 module for BLE/WiFi but this device is untested as of now.
