Hello,
i want to implemented an integration for FuelCell (Efoy)
the fuel cell is connected via serial to another board, and i’ve made a proxy to mqqt, with autodiscovery.
everything is good, but i would like to know the best way to implement a push button to reset fuel cell cartridge (when cartridge is replaced, i need to reset it insinde efoy to let it knwow there’s a new cartridge).
I could use a binary sensor, but reset has not state, it just a action.
i didn’t find a way to publish a service via mqtt auto discovery. Is it something i’ve missed in documentation?
What will be the best way to do this?
Thanks
Johan
