I very much like the Toon/Boxx integration, works ok.
I have a nabu casa url and also added Google Assistant. Now there’s something strange. The thermosthat shows up in GA and Google Home. But I can only turn holiday mode on/off (which I’ve done once I guess in the 3 years that i own a Boxx. And I can turn the thermostat program on/off. Which I also never do. I just set a pre programmed stated (home, away, comfort or sleep). I don’t know if this is a limitation of GA or HA. But i would love to give the new home/away routines a try in GA and if I go away, would love it if I could put Boxx in that state also automatically. And yeah, I know, this is possible in HA already. Yet in HA presence detection stays a gamble and isn’t quite as reliable as I would like it.
