Description

Since Homeassistant 2024.1.3 Betterthermostat crashes when controlling devices or when trying to enable debug

Steps to Reproduce

1. Start Homeassistant
2. Try to enable Heat on Betterthermostat Thermostat
3. unresponsive web interface, docker restart fixes homeassistant

Expected behavior:

Enabling Heat

Actual behavior:

HA crash

Versions

HA 2024.1.3, BT 1.4 and tried with BT 1.5 latest beta

Additional Information

[b1ggi]

maybe its not a btt error, i think its a underlying problem of the hvac/tuya trv

https://github.com/sockless-coding/panasonic_cc/issues/161 and one of my one tuya thermostat is out of battery

maybe these two underlying problems crash homeassistant

[joeblack2k]

yeah same here with tado:

2024-01-14 16:30:01.626 ERROR (MainThread) [custom_components.better_thermostat.utils.controlling] better_thermostat Better Badkamer: ERROR controlling: climate.badkamer_tado_thermostaat Traceback (most recent call last): File "/config/custom_components/better_thermostat/utils/controlling.py", line 53, in control_queue _temp = await control_trv(self, trv) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/config/custom_components/better_thermostat/utils/controlling.py", line 92, in control_trv await update_hvac_action(self) File "/config/custom_components/better_thermostat/events/trv.py", line 256, in update_hvac_action self.bt_target_temp > self.cur_temp + self.tolerance TypeError: '>' not supported between instances of 'NoneType' and 'float'

[joeblack2k]

according to chatgpt 4 (don't slap me haha)

The error message you're encountering is a TypeError, indicating that a comparison is being made between a NoneType and a float. This happens in the update_hvac_action function, specifically at the line where it checks if self.bt_target_temp is greater than self.cur_temp + self.tolerance.

The error suggests that self.bt_target_temp is None, which cannot be compared with a float. To fix this error, you need to ensure that self.bt_target_temp is assigned a proper float value before this comparison is made, or you need to add a check to handle the case where it might be None.

trv.py.zip i let ChatGPT fix it for me.. replace the file in /custom_components/better_thermostat/events/

[h-dreyer]

same for me with tuya tv-02 devices using z2m. Tryed BT 1.4. as well as 1.5 beta 4.

Hope to have found a relevant snippet from the log:

So this issue is a pretty heavy issue. It just makes it completely unusable. @KartoffelToby do you have time / plans to fix this or is it not possible right now? Otherwise I'll need to dive in and check the code, but perhaps it's much faster for you to see where to fix it.

maybe these two underlying problems crash homeassistant

It was like i suspected, the two individual problems (thermometer/thermostat reachabilitiy) lead to the crash.

[joepbuhre]

I have the same problem with my Honeywell Lyric T6 which is on netpower. I use a Sonoff Temperature sensor as external sensor. So I will dive into this, but other people also indicated this issue. Either way Home Assistant should not crash, with the only option being to restart.

So I dug into this a bit because I really wanted it working. What I discovered was the whenever HAOS restarted for whatever reason, the Better Thermostat card has no value for target temperature set. This meant when it got to line 256 (self.bt_target_temp > self.cur_temp + self.tolerance), self.bt_target_temp was "None". Comparing the "None" to the cur_temp resulted in a failure and therefore a crash. I can't tell you why it causes HAOS to crash out like that. But... what I did do to resolve was add a couple of new lines at line 221:

if self.bt_target_temp is None:
    self.bt_target_temp = 5.0

Now, when HAOS first starts up, this script runs, and the bt_target_temp is set to 5C. This is reflected on the better thermostat card. And no more errors or crashing.

I'm sure there may be a deeper rooted problem, or a more elegant way of fixing this up - but my coding knowledge is quite basic so is a good temporary fix as far as I'm concerned :)

EDIT: Typos. Also to add, I've been running like this for over a week now and it's been great!

Interesting! Will probably open up a fork for this! Do you have a file where you put this?

[joeblack2k]

Yeah my fix is in a few post above 👍🏻

[wtom]

Could you make a PR for that? Then it can be merged in the next release.

[KartoffelToby]

@joeblack2k @wtom I added the "Fix" in the Beta 1.5.0 V5 but this is only a fix for the symthoms, we need to find out why the vars are empty at this point.

[h-dreyer]

Not really fixing it for me, but still I'm not deep into this. I have downloadet the last version of the beta 5, checking trv.py code if the "none" fix i includet. Seems to be.

I think this is the relevant log to the event, forcing ha not to respond and only respond by restarting the container:

Same issue here with HA 2024.3.3 and Sonoff TRVZB. This error shows up in the following situation in my case: Restarting HA and trying to set BT temperature or switch without the underlying climate entity being available. In my case some zigbee connection issues caused the same situation by restarting ZHA and BT devices.

I found that BT is running into an infinite retry loop that locks HA. Even though it's not the root cause, it's better to use a finite number of retries with some backoff.
