Hi,
It is, I followed the steps in the link below.
In case that doesn’t work:
- Remove the thermostat from the wall and remove a battery
- Turn boiler off, then on again
- Hold down central heating button on the boiler receiver until light turns pink then release
- Hold down the central heating button again until the light turns amber with double flashing
- Pair with Home Assistant - I will be using ZHA’s ‘add device’
- At this point the amber flash may change to a single flash
- Stop ZHA from searching for devices by pressing back
- Replace the battery in the thermostat and allow to boot
- Press and hold the menu and back buttons, allow the countdown to finish and release when you see welcome - after selecting a language, it will enter pairing mode.
- On ZHA select the boiler device you added earlier, now click “ADD DEVICES VIA THIS DEVICE”
- The thermostat should now pair to the boiler receiver. The amber light should turn green.
Other than the issue with signal that I’ve just discovered it’s worked a lot better than through the Hive integrations.
