Emergency Heat and Celsius - Cannot change setpoint because temperature is null

[dmhuisma]

Describe the bug
Home assistant is not allowing me to change the setpoint temperature in the thermostat UI. It appears that this is because the temperature attribute of the climate entity is null. Here are my current climate attributes. It has been like this for about a week or so. I definitely have not received a thermostat update within this time frame, the version is currently 4.25.0070 (s40).

hvac_modes:
  - "off"
  - cool
  - heat
  - heat_cool
min_temp: 4.5
max_temp: 32
target_temp_step: 0.5
min_humidity: 15
max_humidity: 45
fan_modes:
  - auto
  - "on"
  - circulate
preset_modes:
  - schedule IQ
  - summer
  - winter
  - spring/fall
  - save energy
  - away
  - cancel hold
  - cancel away mode
  - none
current_temperature: 20.5

Here is the UI, unable to change the temperature.

There was a home assistant log entry about this, but it has since gone because I have restarted after an update. I will add a comment if it comes back. It was specifically an error about the temperature attribute.

(Unrelated, but does anybody have a higher version for their thermostat? I am currently having heat pump issues and I'm told a new update came out late last year addressing it, but I do not know if I have it).

Thank you for this integration!

To Reproduce
None, it occurred on its own.

Expected behavior
I expect to be able to change the temperature within home assistant, and the temperature entity should not be null.

You are running in Celsius and your Lennox system is running in emergency heat mode - that is what the aux = true means. The code branch for handling this in Celsius is inconsistent with the code branch for Fahrenheit and will return Null in this case - which is a bug.

Is that how the system is running? Furnace is running instead of heat pump?

When the system is in emergency heat mode the heat pump will not run. Don't know if that the issue you see.

[dmhuisma]

My heat pump is not running very well, we have it running with aux because otherwise our house will get cold. So the aux setting was intentional on my part, didn't realize it might be contributing to the issue.

Got it, I have a fix in process for the API. For now if you want to set it use the panel or take it out of aux mode change it and put aux back on.

[PeteRager]

I have fixed the API. I will create a new release of the integration tomorrow.

If you want to test the new version, you will need to edit the manifest.json file in the custom_components/lennoxs30 directory

Change this line from

  "requirements": ["lennoxs30api==0.2.12"],

to

  "requirements": ["lennoxs30api==0.2.13"],

And then restart home assistant and it will pull down the new version of the API with the fix.

If you don't feel confident about editing this file, that is ok, I will create a new version of the integration tomorrow AM Eastern Time.

Thanks for the quick fix. Ive pulled in the new version. At first glance it appears to work but I'll report back of I see any issues.

[PeteRager]

I've created a new release that contains the API fix.

https://github.com/PeteRager/lennoxs30/releases/tag/2024.2.0

At some time when its convenient upgrade to it. Basically it just contains the updated manifest file. So functionally it will be identical to what you are running.

Thanks for reporting the issue.
