I got my Danfoss Ally thermostats today. I’m using ZHA with a Conbee 2 stick. They paired with no problems, even though my network is pretty large and one of them is far away. Regulating from HA works, and the display on the unit updates. Regulating on the unit also updates to HA. They’ve been installed for 9 hours now, and as far as I can tell everything works beautifully.
Feature wise they are pretty boring. At least with ZHA, what you get is only the climate device and a battery sensor. Will miss the sensors (temperature, humidity and especially “heating”) that came from Tado, but getting to remove my last bridge and cloud service is so worth it.
Looking forward to make some neat automations with “proximity”, weather etc.
