Can I integrate Hive Active Heating into HA without the Hive Hub?

Many thanks @jampez77

Writing up the procedure for others’ benefit

  1. Remove the thermostat from the wall and remove a battery
  2. Turn boiler off, then on again - this should cut power to the boiler receiver
  3. Hold down central heating button on the boiler receiver until light turns pink then release
  4. Hold down the central heating button again until the light turns amber with double flashing then release
  5. Pair (the boiler receiver) with Home Assistant - I will be using ZHA’s ‘add device’ function
  6. At this point the amber double flash may change to a single flash
  7. Stop ZHA from searching for devices by pressing back
  8. Replace the battery in the thermostat and allow to boot
  9. Press and hold the menu and back buttons, a countdown should appear on the screen, allow the countdown to finish and release when you see ‘welcome’. After selecting a language, it will enter pairing mode.
  10. On ZHA (or similar), select the boiler device you added earlier, now click “ADD DEVICES VIA THIS DEVICE” - the Thermostat must be connected to the ZigBee network via the boiler receiver we added earlier
  11. The thermostat should now pair to the boiler receiver. The amber light on the boiler receiver should turn green.

Edit: In October 2024 I had some difficulty re-creating this, the main issue was that the “ADD DEVICE VIA” in ZHA didn’t seem to perform as described and that the battery powered thermostat would be connected to some other zigbee device on the network topology. After much trial and error, I instead used ZHA Toolkit’s handle join action with the device reference field set to the HIVE Boiler’s IEEE 00:1e:5e:09:02:27:d7:90
