Use the menu on the left or the search to find the information you need. Some starting points:


If you have a Gateway Premium II or older it is strongly recommended to upgrade the ESP8266 to an ESP32. Especially the HA MQTT Discovery function puts the ESP8266 to its limit. Also by upgrading you get a lot of new features and added stability. See this page for more information.

For those who already have a Premium II or other ESP8266 Gateway and you would like to get a new ESP32 Gateway I can offer a nice discount. Send me an email via the contact form on the website.

Sometimes the menu on the left doesn’t scroll properly. Via the Table of Contents below you can see it all.
