Hi All,
So I’ve recently replaced my old and failing Drayton wiser smart TRV’s with shelly TRV’s in preparation for the winter. So far they seem ok but I’m letting them run as they would in the winter (minus controlling the boiler) but they seem to have some odd quirks so i wanted to see how everyone else is using them
For me, i have each TRV configured with external temperature sensors and with underfloor heating mode enabled so the internal sensor does nothing. I then push rest calls to the TRV’s using data from my external sensors to control them.
Each sensor has auto temperature control enabled with the fast heat option disabled. I then use the HACS scheduler-component to control the temperature set points on a schedule so all my configuration is in home assistant if I need to make changes
It’s only been a few days so I’m still learning but I have spotted odd behaviour with the TRV trying to turn the heating on. For example, here is the HA chart for this morning
You can see it turns on as it should, but then randomly turns off for 10 minutes before deciding to come on again. It then remains on until the temperature hits 20.9 and then 5 minutes later turns itself on again for 5 minutes, even through its already warm enough
I had a similar starting behaviour yesterday as well, except yesterday it was 5 minutes that it was off for. It did not however have the weird issue of turning itself on again after the room warmed up
Right now its feeling like I may have to disable auto control and manage the valves manually to make sure it works a little more as you’d expect but I wanted to see what everyone else is doing first?
For example, ideally it would turn on when it was 0.5 degrees below the set point and turn off at 0.5 degrees above so it has a gap/swing. Right now it looks like if I set 20, it would turn on at 19.9 but that could be triggered by someone walking past a sensor for split second so it almost seems too sensitive
Many thanks in advance,
Jamie
