Integrate Home Assistant

Auto discovery

Home Assistant discovery is enabled by default on all binaries and platformio configurations except for UNO. With Arduino IDE please read the advanced configuration section of the documentation.

First enable discovery on your MQTT integration in HASS.

The gateway will need an MQTT username and password, you have to create a new user(recommended) into Home Assistant->Configuration->Users (available in admin mode) or use an existing username/pwd combination (not recommended). This user doesn't need to be an administrator.

::: warning Note The max size of the username is 30 and 60 for the password. :::

OMG will use the auto discovery functionality of home assistant to create gateway and sensors into your HASS instance automaticaly.
