- Notifier function (multiple ESPs sync color via UDP broadcast)
- Support for power pushbutton
- Custom Theater Chase
- Full OTA software update capability (only ESP8266)
- Full OTA software update capability (HTTP and ArduinoOTA)
- Password protected OTA page for added security (OTA lock)
- Alexa smart home device server (including dimming)
- NTP and experimental analog clock function
