Description

When heating is turned OFF (by Window opening or OFF switch in Dashboard), it will not turn on to "heat" when window is closed or HEating button pressd on dahsboard.

Steps to Reproduce

open window / press OFF on dashboard or in automation with entity better thermostat type: set_hvac_mode hvac_mode: 'off'
close window/ press ON on dahsboard or in automation with entity better thermostat type: set_hvac_mode hvac_mode: heat
check on thermostat on heating, it´s still shows "OFF" dashboard shows "heating"even thermostat is still "OFF"

Expected behavior: thermostat turns ON

checking integration with standard thermostat device "climate.heizung_bad_thermostat" and dahsboard it works like expected dashboard / on/ off or also in automation with. type: set_hvac_mode hvac_mode: 'off' type: set_hvac_mode hvac_mode: heat Works as expected

heating turns ob with hvac_mode: heat Actual behavior: heating still remains OFF with " hvac_mode: heat"

Yes, the code is buggy. You have to change the code and set mode to heat on every temperature set.... It is easy and it works. Dont know why the code owner does not fix this....

GravitySandwichh commented 8 months ago

Experiencing a somewhat similar issue with these thermostats. BetterThermostat is turning off my heaters at random causing my house to be freezing. I had to make an automation that keeps turning it back on but it's really annoying.

That is good to know, that it´s easy to fix. Can you remeber what file needs to be edited and do you have a code? One of the files in the main folder of better_thermostat?

acid115 commented 8 months ago

Yes, climate.py I did some changes, that work for me. My BTs doesnt change to hvacmode=off randomly anymore, except if window/door is open. That is a big problem a lot of people have. I use a schedule to change the temperature over the day, or when i leave my home, or if no motion is detected in a room, but i dont need to switch off. So every temp change results in a hvacmode=heat. Also if the hvacmode is unknown (default was off), i beleave that this is the problem why the software switches to off randomly. And i have set the max temperature of the real trvs from 30/35 to a fixed value of 25, because 30 is too high for me (overheating sometimes).

It's open source, everyone can create a PR and it's more than welcome.

Thanks for the code. I will try

acid115 commented 8 months ago

Forget it, i have some trouble now with these changes.... The real trvs does not really stop heating, if target temp is reached. BT sets the target temp of real trv to the current temp of the real trv, if bt-target-temp is smaller than messured temp by ext. temperature sensor.

Now i have ti find out, why the hvacmode switches off sometimes...randomly...

Yes I can agree, I tested and it´s no difference

I added This at line 161: ... self.bt_hvac_mode = HVACMode.HEAT .. [Code] and another section similar.

Also after HVACmode=OFF, the TRV didn´t turn to Heat again

ChristophFeile commented 8 months ago

After no sucess with this: self.bt_hvac_mode = HVACMode.HEAT I tested following as service:

climate.set_hvac_mode hvac_mode: Off on BT entity -> as aspected TRV OFF climate.set_hvac_mode hvac_mode: Heat on BT entity -> reaction: dashboard shows Heating ON, but TRV stays OFF

now tested climate.set_hvac_mode hvac_mode: Heat on REAL entity of TRV -> TRV turns ON to HEAT

I gues there is some bug in the implementation of climate.set_hvac_mode hvac_mode: Heat in the better thermostat code.

Does anybody knows where to fix?

ChristophFeile commented 7 months ago

OK, my workaraound, I created an automation that watches the window opening sensor. If it´s closed, it calls a service to set HVAC mode to HEAT of the real TRV. If someone knows how to fix directly in Better thermostat I apreciate.

Kaot93 commented 7 months ago

I'm having the same problem, bypassed it by writing an automation.

But also I can't use overheating protection due to this bug, if BT switches off the thermostat it stays off.

Hello Christoph,

I have the same problem with my following combination:

BOSCH Radiator Thermostat II → integrated via the BOSCH Smart Home App and the BOSCH SHC II
BOSCH Smart Home Controller → integrated in HA via the HACS BOSCH SHC Tschamm integration
Custom integration Better thermostat
Custom integration scheduler → GitHub - nielsfaber/scheduler-component: Custom component for HA that allows the creation of scheduler entities 1
Zigbee window sensor
Zigbee room temperature sensor

I have also reported the problem in detail here:

https://community.simon42.com/t/problem-mit-kombination-bosch-hkt-ii-hacs-bosch-shc-tschamm-integration-better-thermostat/12931

Can you tell me where you installed your workaround? Maybe you can give me the code?

Many thanks for your help.

ChristophFeile commented 7 months ago

Hey Secret007, thats quiet easy. Just over the GUI, you need no code. Create an automation. Watch your window contact, if closed, set climate HVAC mode to heat. But important, you have to use the real thermostat, NOT the better thermostat.

MetroAffe commented 7 months ago

This only happens to me when external room temperature sensors are set up. Without them, everything works great. Could you please test this scenario as well?

ChristophFeile commented 6 months ago

I tested, I removed external temperature sensor from better thermostat entity. The behavior changed, when opening the window, the thermostat was NOT turned OFF, but also did not reduced temperature. Different, but not what expected.

Peviox commented 5 months ago

i have the same problem with my ts0601. when i open the window the hvac mode stays at "heating" for a random amount of time and at some point changes to "off" and doesnt turn back on. this also happens randomly throughout the day. mainly when the target is lower than the current externally meassured temperature (when turning down the temp e.g. at night). my workaround for this is a very simple automation, that listens to the hvac mode of each BT entity and if it changes to off, it changes back to on a second later. its not a nice solution to a problem, that shouldnt exist but it works. the biggest problem is, that if the trv is on and this problem occours, even tho the mode changes a second later the trv fully closes and opens back up. from the log files i cant make out why this happens
