Picked up a used CT100 for $15 off of ebay. It's local or bust baby! Heck I don't even know if I knew Radio Thermostat had an app! HA all the way. Got rid of our google nest (came with the house!)

Each row is one report from a GitHub thread, an integration’s docs, or r/homeassistant. Check the date and the linked source before you buy.

In ReReHome

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
