Just wondered if anyone on here is using a HA compatible one.
Zigbee or Z-Wave would be fine.
Unfortunately, the controllers I got with the main control unit are Heatmiser.
They use Zigbee, but the manufacturer's own implementation which requires buying and running a proprietary hub (and sod that!)
Rather annoyingly, the controllers are pretty functional!
The manifold wiring centre itself (UH4) just works by connecting 240v lines, so shouldn't be too hard to have HA connecting the right loops at the right time.

I've considered just doing this with shelly relays and setting up a thermostat in HA, so if anyone has homebrewed an interesting solution, I'd also be interested to hear!
