SGS01 Temperature celsius vs fahrenheit

[Joao-Sousa-71]

I've bought a SGS01 Soil moiture (BLE version) that works great with this integration however I was having negative temperatures in HA. I'm based in Europe and therefore the temperature units are set to Celsius.
The Smart Life mobile app was set also to Celsius, but SGS01 was reporting the tempertaure in fahrenheit.
The way to fix the negative values was going to the Tuya Developper and in the device debugging do the following: Select the temp_unit_convert to "C" and press the send instruction bellow.

Hope this can help somebody.

I think I have a compatible device since it got detected as ble_smart_plant_moisture which is the config for the SGS01:

In the SmartLife app it's ignoring my profile settings to use Fahrenheit and displaying in Centigrade. But HA is converting fine to Fahrenheit.

However, HA doesn't get any updated values unless I view the device in the SmartLife app. Then I see that apps cycle through historical values to present (seems it's collecting the recorded data off the device) and then both SmartLife and HA have updated values. Unfortunately, this means the HA integration isn't really useful if I have to keep running the SmartLife app anyway and also have to use that to get a complete historical graph. Are you seeing a different behavior?

@AdrianGarside I have a similar behavior but we should be close to have that fixed. See this thread #1696
Update: It is fixed.

Ok, so making the temperature unit selectable and setting it every 30 minutes via an automation triggers an update as a side effect?

[Joao-Sousa-71]

@AdrianGarside mine is working without flipping from Celsius to Fahrenheit…
I’m sending to change to Celsius every 30 minutes.
If you reduce too much the frequency the sensor do not react. Here are my charts from the last 24 hours:

Hmm, I’ll try doing that in the automation - it didn’t seem to work through the UI.

I couldn’t get a select/set_option of c / f / Celsius / Fahrenheit to work - the automation gave an error that none of those were valid options. So I was setting firsf / last instead which worked and didn’t throw an error. Not sure why I was having that problem.

Try celsius or fahrenheit in all lower case

[AdrianGarside]

I thought I had tried that too but that worked. And while there no log of the action in home assistant it does seem to be triggering the device to update the temperature value in my single test just now.

Looking great now:
