-- Publish auth data: Enable to publish authorization data to the MQTT topic lock/log
+- Publish authorization log: Enable to publish authorization data to the MQTT topic lock/log
+- Save auth log number to flash: Enable to save the highest Nuki lock and/or opener auth log number to flash on change. Prevents duplicates in the rolling log but slightly increases flash wear.
 
 #### Nuki Lock/Opener Access Control
 - Enable or disable executing each available lock action for the Nuki Lock and Nuki Opener through MQTT. Note: GPIO control is not restricted through this setting.
