Welcome to the EMS bus product documentation!

You can find all information about the EMS bus and EMS based products in this wiki.

If you want to go back to the webshop click HERE.

You can also download this whole wiki as one user manual in PDF.

Note

If you are running firmware V3.4 or higher we have a new wiki HERE.

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

• EMS Bus Gateway information and instructions

• Information on the EMS interface boards

• Information on the EMS bus HAT for Raspberry Pi

• General info on the EMS bus

Note

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.
