@maty said in MySensor on Hass.io - can't get it work:
/config/mysensor
Default path seems to be generic and not really useful, at the beginning I had problems with understanding this as well. Take a look at the full location where your home assistant configuration files are located, this could be a good location. and add "mysensors.json" at the end (this file will be created and you can name it anything.yson).
like mine is "/root/.homeassistant/mysensors.json"
