I’m looking for options for radiator valve control. I’m fairly open as long as it’s control over the radiator valve and not some other smart home system. I was told that OH supports ZWave and thus ZWave Danfoss (and others) valves. However when I went to look at these valves the ones I found were…

[image] paulcam: So what are my options? Get separate valve and temp sensor. All products to combine these will work the way you say you don’t want them to. You can get valves meant for underfloor heating and mount them on your radiators.

You can keep your set temp at max and turn it off completely when some other sensor tells you that you’ve reached desired temperature… i use multiple sensors, and temperature that valve reads is only one of the temperatures for that room… it’s not the one triggering the device off…

[image] paulcam: I’m not completely against using 240V electrical actuators and running power to the radiators I want to control. In fact I kind of like the robust simplicity and no batteries to worry about. I’d suggest the 4 wire 24v versions, with microwitches to confirm the valve is fully …

See here: [image] My Central Heating Solution using Thermal Actuators Solutions Hi all, I’m sharing with you here my heating setup in the hopes that it can help someone (and to just show it off, too, I guess. My house is quite typical of UK houses, where I ha…

[image] MDAR: I’d suggest the 4 wire 24v versions, with microwitches to confirm the valve is fully open, which in turn could signal the Heat Call of your boiler / heat source. Thanks, these look grand. One worry I had was a lot of these valves are £50-60 which would be too much to get one a…

[image] paulcam: One worry I had was a lot of these valves are £50-60 which would be too much Really? I rarely pay more than £15 each for them. For example, this 24v 2 wire version https://www.tus-ufh.store/wet-underfloor-heating/thermostats-controls/actuator-heads/01213202-emmeti-24-volt-…

[image] MDAR: One worry I had was a lot of these valves are £50-60 which would be too much Really? I rarely pay more than £15 each for them. I think it was because I was seeing the smart valves with thermostat etc. ZWave and others.

One solid bit of advice that was given out on here some time ago was.. “Let openHAB2 control a thermostat, rather than being the thermostat”

[image] MDAR: “Let openHAB2 control a thermostat, rather than being the thermostat” On a slightly sore point (for this forum) I probably won’t be using OpenHab for heating control. As a professional software engineer I already invested more than a few hours in my own system which I hope to k…

Let them fit the trvs. The actuators are then a straight swap. If one fails you can always put the trv back on temporarily.
