If you look at the heat report in the app the set points are the straight lines (purple in your screenshot but equivalent in the heat report). If the temperature is still rising significantly above the set point it is probably not Wiser that is causing it. Wiser would have closed the iTRV when the room was at the set point. If you confirm all your iTRVs have the latest software (Devices page in settings) then I would check the batteries and the valve pins (take off the iTRV and push the pin down) for the rooms that are overheating.
@msp1974 I just noticed the iTRV firmware version shown via āSettings->Devices->Wiser iTRV Xā showed the old version (0000ea60). Where as accessing the attribute elsewhere shows the updated version (0000ea64). I refreshed, logged out and back in, but only a restart updated the version info for the device pages.
Please share the yaml for your mini-graph card.
Yes, as it is part of the device setup, this only gets created on a restart or by reloading the integration (from the integrations page select reload option)
I donāt know why I said climate card. It is just the History Graph card (type: history-graph
) with a climate entity included (e.g. climate.wiser_living_room
). Sorry for any confusion.
I have had exactly this problem in 2 rooms one with room thermostat. The system seem to be working to a set point about 1.5 deg higher than that programmed. At one point the room stat showed a set point of 16, a room temp of 17 and the flame symbol. The room was definitely turning on the boiler and the valve as open. If the set was within 1.5 deg of room the flam would show.
When I added a room stat to the second room exactly the same happened.
I call the help line and was told to reset both TRV and room stat. I did this and the strange behave of the room stat stopped. I have yet to go though a heating cycle to see if it works for real when I am not interfering.
As this is my first post I would like to say a big thank you those that produce this integration .
A they say just up the road in Glasgow
" Its pure dead brilliant"
Thank you, we love it too
keep us posted if the reset worksā¦
Welcome to the community. Maybe itās a problem with the Scottish weather/temperatures I am also just outside Glasgow.
I did wonder for a short while and even checked to see if there was a āClimate Cardā. Realised pretty quickly you meant the History Graph Card though. Thanks for confirming.
I think you may be right about the weather.
I am fairly certain the reset has fixed the strange room stat problem and the system seems to working to the correct set point but I still get heating demand above the set point (just).
looking back through the history this was ok on 30/11/22 then started on 1/12/22 and has happen ever since to some extent.
The set point issue is only a couple of days old.
I moved my Boiler return temp sensor to the input pipe of the radiator ( wiggle blue line ). It rises every time valve opens and the boiler fires (it is lightly loaded so on a short cycle ) As some of these do not coincided heat demand I think I could still have some leakage passed the valve. ( it is on the ea64 firmware and been recalibrated several times )
I assume when there is no heat demand the valve is closed.
I hope the screen shots post ok.

For background Wiser system installed Oct 2018 HA set about 4 months ago though I have just used it to monitor wiser. Combi Boiler (no Eurothem )
I wanted to post a picture off the heat demand above the setpoint but found I can only post one image per post so I thought I would cheat and reply to my own post
It does, thanks for explaining.
Since new updates few weeks ago it seems they changed how identify
works. It used to be - click identify
, lights start flashing shortly after, click OK, lights stop flashing.
Since update it works like this on all my TRV: click identify
, wait at least 1min, lights start flashing, click OK, in about 30sec lights stop flashing.
Iāve raised it on official community https://community.se.com/t5/Schneider-Electric-Wiser-Forum/Identify-TRV-no-longer-works/m-p/417035 but I donāt think there are any actual engineers looking at posts.
Question for @jamiebennett
Why is my Hallway room thermostat calling for heat when the current temperature is above setpoint?
Image shows current temperature as 19 degrees but the setpoint is 18 degrees - confirmed that the roomstat has turned on the boiler and opened the TRVās. Are the TRVās temperatures used to compute the overall room temperature (thought the point was that the roomstat overrode TRV temperatures).
Only way to get the roomstat to stop calling for heat is to drop the setpoint to 17.5 degrees but resetting it back to 18 degrees restarts the call for heat.
Note that the wiser mobile app does NOT show that the room is calling for heat.
Iām not convinced that boiler works efficiently when call for heat is done every 10min and lasts for 5min or less. I understand this might be so heating doesnāt overshoot the target, but this behaviour is still present when room is below target by 2C and I know it will take at least 2 hours of heating.
I have old condensing boiler and dumb gas meter so I take meter reading every day at same time and record how many hours heating was on from HA. Yesterday rather than allowing wiser to do its own on/off dance, Iāve set rooms demanding heating to 25C - when difference between current and target temperatures are big enough Wiser demands constant heating. After each room reach desired temperature (20C) Iāve cancelled all overrides and let things go back on schedule. Iāll do this for couple more days, but so far gas usage per hour of heating is less!
Iām wondering if someone with non OpenTherm boiler and ability to track gas usage automatically done this test?
Interestedā¦ like u i was wondering about the on/off dance wiser doesā¦
I think i read there was some research done on this
It might be still modulating as it measures the flow temperature and compares it to the one which was defined in the controller built into your heater. (Might be just a knob on the front.)
There might have been, but I doubt they tested old tired boilers heating non insulated solid walls house!
On the research note - temperature TRV allegedly predicts to be in centre of the room. In my case it is only relatively close in 1 out of 5 rooms - the one in which temperature only fluctuates by 2C. Rooms which are heated only some hours a day either shows too low or too high temperature.
Iāve also removed TRV from radiator, put next to thermometer and let it settle - sometimes temperatures are matching, sometimes their are not, but I canāt see any pattern to it.
If you change the Heat Source Type
on the hub to Oil Boiler
it shortens the cycling frequency to 3 times an hour instead of 6 for Gas Boiler
. Iām not sure if there are any repercussions from doing this, or whether it would be a more efficient use of gas by cycling less. Just thought it was worth mentioning.
This is great insight - I can see no reason not to try it and let data speak for itself. Only thing Hub can do is to issue ON/OFF commands anyway. I have few questions:
- How to set
Heat Source Type
? Wiser app doesnāt seem to work. Can it be done via HA? - Is behaviour based on
Heat Source Type
is documented anywhere? - Do you know how
Heat Pump
type works?
Thanks
