 * You can rename the *Ampel*. This name will be used instead of ESPxxxxxx for CSV files and the mDNS address. You'll get a new CSV file after renaming, which can be convenient, e.g. to indicate at which location the measurements were made.
 * If you forgot the password, you can send `reset_config` as command, and `reset` the ampel.
 * If you disabled WiFi, you can enable it again with `wifi 1`.
+* You can enable CSV by clicking on "+CSV", or disable it by clicking on "Remove this set".
+* The same applies to MQTT and LoRaWAN.
+* If you disable a set, the parameters are still saved, and will appear again once the service is enabled.
