After British Gas bought AlertMe back in the day, they brought out this thermostat and receiver combo.
They call it Hive Active Heating and it works very well. The thermostat is wireless and can handle heating and hot water scheduling. It talks to the boiler controller, which is actually the brains of the operation.
The system is very popular here in the UK and it's well implemented. Though remote control relies upon your internet connection and the Hive Hub, local control is truly local and the system can operate without any hub at all, the thermostat and receiver communicating directly with one another.
For some reason I've seen fit to bring this to Hubitat, so here we are!
Search for "hive" on Hubitat Package Manager (HPM v1.8.7 or later is required) or you can install manually:
- BirdsLikeWires Library Bundle - Bundle URL: ZIP
- Hive Receiver Driver - Import URL: RAW
- Hive Receiver Heating Driver - Import URL: RAW
- Hive Thermostat Driver - Import URL: RAW
All three components are required and the Library can be installed on Developer Tools > Bundles > Import ZIP, though HPM is the easier way to go.
NOTE THE BETA TAG!
What doesn't work?
-
Remote-Controlled Boost
Setting boost mode works, but despite the correct boost duration being sent, the system freaks out and sets a countdown of over 5 hours. Not good, and this option is currently disabled. -
Remote-Controlled Hot Water
There are two versions of the system, one with the receiver pictured which is dual-channel, the other with a heating-only single-channel receiver. Control of the hot water channel is identical to the heating channel... except the hot water channel never reports its values and must be polled for information. I will add this eventually once I've worked out a neat way of doing it. -
Scheduling
You can set a schedule through the thermostat and use this driver to go between auto (schedule), manual or off modes just fine. This is a good thing to do as it doesn't rely on hub communication to run your heating programme: it is stored in the receiver directly attached to your boiler. Very clever. What this driver doesn't support is modifying the schedule via Hubitat. I can figure out the Zigbee just fine with some time, but I don't know how to integrate this with a reasonable UI in Hubitat.
I'm testing this out at the moment with my test setup (not on my actual boiler, yet!) so if you fancy messing around, go for it. Don't blame me when your family complain that the system didn't come on in winter.
Follow these instructions to reset your system. Keep your Hubitat hub in pairing mode during Step 6.
