Thermostats often not available

[pillemats]

HI

i am using aqara e1 thermostats with the newest version of BT and HA.

sometimes i had the problem that the therostats are not available, but the real ones do.

i found out sometimes the problem can be that some sensors i configured are not available.

now in my living room, all my sensors are online but still the TRV is not reachable in BT.

here are my configs:

the external sensor is an aqara temperature sensor humidity is the same window and door contact are a group of binary sensors in HA outside temp is my bresser wetterstation, works over weatherundergound

can somebody help my to get a solution?

Thanks

Sounds like a signal problem, here the 5yo Z-Wave mesh with plugs as repeaters is more reliable than the new bought zigbee units. Neighbors WiFi over day deplete the zigbee signal sometimes. Will buy two NOUS plugs to booster this up, my Zigbee runs at ch15 what is jammed by WiFi channel 3-4 Information about the channels WiFi vs Zigbee can be found in this thread: https://community.home-assistant.io/t/almost-at-breaking-point-with-zigbee/283768

You can take a smartphone with a WiFi scanner app to look, how busy the channels are.

ah ok, but every other device works great. i am using over 160 zigbee devices. in my opinion i think this is enough for a good connection....

what can i do now?

[pillemats]

It can’t be an zigbee problem, because the real trv is available and works

[pillemats]

is there any solution?

I have the same issue on only one thermostat (also Wohnzimmer) ... a quick solution would be nice.

EDIT: Fixed it! I had a missing/unknown/unset calibration number on thermostat ... setted it and it works.

[SvePu]

@pillemats Please enable integration debugging and check log file for issues.

[pillemats]

Ok I did it! An now? Wait?

How did you do that? Are you using aqara e1 too?

[SvePu]

@pillemats Do you have some issues in log file? In case of, please post it here!

I'm using zonnsmart thermostats TS0601

[pillemats]

Where I can find the log?

[SvePu]

• Go to => http://homeassistant.local:8123/config/integrations/integration/better_thermostat
• Activate "Debug Logging" for some seconds and deactivate it .... then you can save the log file e.g. on desktop.
• Open this logging file and look for "better_thermostat" entries.

[pillemats]

Ok i will try I in the evening when i am at home

[pillemats]

here is the logfile

home-assistant_better_thermostat_2023-11-11T20-31-32.943Z.log

at the time i get the debug log Gästezimmer, Kinderzimmer,Küche and Wohnzimmer was not available

hopefully you can read it

[pillemats]

is there any solution?

now i tried to config BT without any contact sensor like door or temperatur.... the TRV in ZHA is connectet and works perfect. in BT the TRV is not available

[pillemats]

Any news? It is so terrible that no trv is available although the original trv is available and works great

[pillemats]

I don’t think that i am alone with this problem

[pillemats]

is there any way to get an solution?

Same issue for me for about a week now. Will need to analyze the logs and report back.

[jrabensc]

Traceback (most recent call last): File "/config/custom_components/better_thermostat/climate.py", line 563, in startup if self.hass.states.get(self.weather_entity).state in ( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'NoneType' object has no attribute 'state'

From debug log.

[pillemats]

What this means? Please look at my log file above. Is this the same error ?

[jrabensc]

Just fixed this issue by removing all sensors from the thermostat, saved and added the sensors again.

[pillemats]

i tried this before... but the thermostats also often not available

i will try it again and will report

EDIT: It works! hopefully it is permanently fixed

[pillemats]

@jrabensc

one of the trv dont work.... the other works

at the one i delete the sensors and after saving i readd it... but the same as before

[pillemats]

now the next one is unavailable.... i think this might be a temporaly solution. i dont want to look every day in HA to delete all the sensors and add it again

[cubertt]

i have the same problem here... On z2m it is reachable, in better thermostat not. If i have time, ill check the logs

[pillemats]

@cubertt any mistake in log found?

[bsafh]

the BT entity switches to "unavailable" when one of the sensors needed (external temp, outside temp/weather) goes "unavailable".

So you need to check not only the TRV itself, but all of the sensors configured to use for BT for that BT as well.

[pillemats]

i checked this before.... all my sensors are online and works. i tested right now.

when BT switches to unavailable? because some endpoint Zigbee devices could be offline for some seconds and then reconnect

when BT directly switched to unavailable maybe its possible to build in an delay, that waits for example 1h to switch to unavailable

[pillemats]

I have now deleted BT and built my own automations. Now everything works perfectly, without the TRV constantly being unreachable.

It's a shame that the support here isn't that good and it just says "the problem isn't with BT"

Well, everything is working for me now.
