Not namedWorks LocalRelays with generic thermostat in YAML for heating zones
Saved copy
I use a Sonoff 4chPro as the relay for each of my heating zones, wired in parallel with some old-fashioned dumb thermostats as a backup. I've created a thermostat device in Home Assistant configuration.yaml that pairs a thermometer (or an average of multiple) with one of the relay entities. You can also specify a hysteresis and minimum cycle times.

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.
