Incorrect negative temperatures with AEH-W4E1

[togume]

First, thanks for this solution!!!

New install of HA, AirCon does control the ACs, but the temperature is incorrect:

Other ACs and devices with temperature do correctly show up in Celsius.

The LED display on the AC changes to F when controlled via HA.

The AI-Home app on iOS does show the controls in C, but interestingly enough, when controlled via HA, it shows current temperature in F.

Here is the config for the Add On:

log_level: INFO
mqtt_host: 192.168.86.25
mqtt_user: mqtt_user
mqtt_pass: PASS
port: 8888
app:
  - username: email
    password: PASS
    code: hismart-us
local_ip: 192.168.86.25

How can this be fixed?

Update: after trolling other issues, I changed mqtt_host to be localhost. Interestingly, when I next checked the ACs, one of them is still showing wrong negative values, but the other one is showing temperatures as expected. Very strange.

I've restarted the add-on, the browser... nothing.

Still nothing... Very weird! One is still perfect, the other one is still negative. @deiger any clues or things I could dig/try myself to help resolve this?

I'm surprised that hismart-us uses Celsius in the API. Commonly US-marked apps use Fahrenheit.
Will change that.

Weird! And strange that one is fixed and the other one isn’t. Perhaps some race condition made one work.

Thank you good sir!!

Try clearing up the config files (either by uninstall & reinstall, or by ssh into the docker). This will make the add-on rerun the discovery, and create updated configs. Alternatively, you can just edit the config files in ssh.

Could you please paste here the Device info of each of your ACs? You can reach it by clicking the device from the Devices page in Settings.
It might be a matter of the specific model.

Sorry for the slow reply, @deiger! I was traveling and just now catching up on email/home automation.

I'm happy to report that things are now working correctly and the room no longer appears to be freezing! It took a little while because I misconfigured MQTT, but after I fully uninstalled this plugin, MQTT, and also deleted configs via SSH, I was able to get things working perfectly.

In case it's useful, here's what you requested:

I'll close this issue with this comment. Thanks!
