I'm new to Hubitat (just ordered my Hub) and am just moving house as well. In the new house, the heating is linked up to district heating, so there's no thermostat - instead, the temperature is controlled directly on each radiator. For that purpose, I have bought the Netatmo thermostatic radiator valves for district heating - which work with Wifi and Google Home to control the temperature in each room.
However, having now discovered Hubitat, I am wondering whether I should send them back (I can still do so, having just bought them) and should instead buy something that works with Zigbee and Hubitat, locally. Is there anything like that? (I haven't found a Zigbee alternative to these yet).
There are both zigbee and z-wave TRVs available if you’re in Europe.
Most of them should have some basic level of compatibility with Hubitat. There are some threads on community-based drivers for specific devices but the Hubitat team is in the US, so overall this isn’t a heavily developed device type.
It’s a shame because I actually use dumb TRVs in my home in the US. In some cities there are still lots of old steam radiators in use. But the smart TRVs from danfoss, eurotronic, netatmo and others just aren’t sold here .
Edit: Fibaro’s TRV is on the hub’s compatibility list.
Thanks for the answer! I'm located in the EU... I'll check the Fibaro one out - would you say then that this offers the same functionality as the Netatmo ones? Because obviously it would be much better to run my radiators via Zigbee and Hubitat...!
Some have had success with generic drivers and the Tuya valves, but you'll need to search the forum and ask questions in the threads where you find users claiming compatibility. Personally I would stick with the devices listed as compatible for something like that.
There is also a Eurotronic Spirit Zigbee one - would that also work? I'm trying to stick with Zigbee at the moment as I have some repeaters for that...
The Amazon reviews on the Fibaro scared me off - so I'm interested in the Eurotronic one!
I would not recommend Eurotronic (Aeotec is the same). Got 3 installed and about to pull them off. They have a known issue with them and only work best when polled rather than report on change too.
Oh my.... OK! This is really hard - not a small investment and I do need this to work reliably (or my other half won't be very happy it!)
Now I'm thinking maybe I should just go with Netatmo as it seems to be reliable and just miss out on the advantages of running this locally... I'll just use Hubitat for everything else........
I'm not a purist when it comes to running things locally, but do see the advantage... My main concern is simply that it works reliably. It seems people are finding that the Fibaros break quickly in terms of mechanics... So yeah.
In terms of the Eurotronic ones, was the problem with the software side (which presumably will get better, with Hubitat looking to support them) or with the hardware itself?
The other issue Ive found is every week or 2 it would go bonkers and lose control and fully close the valve and greatly overshoot. Goggle it, it's common regardless of platform.
I just want to say: as someone who is new to this: this thread has already blown me away in terms of the helpfulness of the community and the staff. Absolutely amazing! Thank you!

Well if they are doing this it might be a bit harder.. But we will see
