I think your device may have a wrong target temperature property. scale=1 means your device's temperature range should be divided by 10^1, then is 1℃~7℃. Actually is it 10℃~70℃?

[DominoLeChat]

Yes exactly, the temperature range is 10°C ~ 70°C

Well seems I have to add a workaround for these wrong configured device: if the max value is lowered than 10 which is abnormal, I will override the scale to 0. I will fixed in the next version, please try later.

[DominoLeChat]

Ok, thank you for your help !

I have another question, what's the accuracy of your device's actually target temperature, 5°C or 0.5°C?

[DominoLeChat]

I think the accuracy of the target temperature is 0.5°C

[0x5e]

This is really annoying of the wrong schema made by the manufactor. It devided max and min by 1, but devided step by 10...
I can't fixed the wrong data to the correct value then, because the code will never know 5 or 0.5 which is correct. I will reset the props to the default value 10°C~38°C, step=1.

[0x5e]

Please try beta.30. I will consider add device schema overriding in 1.7.0.

[DominoLeChat]

Ok, it's not crashing anymore, but the temperature is incorrect. The set temperature is half of what it's supposed to be and the actual room temperature is completely wrong.
For exemple, when I set the temperature to 30°C in HomeBridge, the thermostat is set to 15°C instead.
And the room temperature sensor is showing the set temperature divided by 5 instead of the actual room temperature.
Thank you for your time.

Can you upload the homebridge log in debug mode when setting temperature and when room temperature changed? And tell me the actual temperature. If it can be solved by schema overriding, I will do in 1.7.0.

I'm a little busy in 2022.11-12, and overriding still needs a lot of work to be done, maybe 2023 we can solve this.

Guys, sorry if off, but I've faced similar issue, a wall heater gets max 25c of heating temp. Is it something what I can change somewhere? On iOT platform I can see range is 10-49 Celsius.

Thx!

When I change the temperature to 30°C coming from 38°C, here's the log :

The actual temperature has not changed yet, but I'll update this issue when I'll get a log of the change.

Here's the log when the temperature goes to 27°C :

It can only be changed by your device manufactor. And can only be changed before product release.

@DominoLeChat Why 38°C => 30, and 27°C => 54, can you have more data?
If you can figure it out, I plan to add two features to let 'wrong device' work:

1. Overriding schema
2. Transform value, like this: https://github.com/arachnetech/homebridge-mqttthing/blob/master/docs/Configuration.md#apply-functions
