Can't change temperature Unit - system ignores the setting - smartdgm_portable_air_conditioner

[gratak]

Hi, I'm trying to change the temperature unit in the climate control card to Celsius, but it doesn’t work. Even though the unit is set to Celsius:

…the control card still displays the temperature in Fahrenheit:

Does anyone know how to fix this? The Tuya app shows the temperature correctly in Celsius.

I'm using smartdgm_portable_air_conditioner.yaml.

It's in your user settings.

Hi, no, that's not it. My account is configured to use Celsius.

I was previously using the wrong config file. I have now created a new configuration based directly on the device properties reported by the Tuya IoT Platform (iot.tuya.com).

The device exposes the following DPS information:

However, the climate tile still shows temperatures in °F.

What confuses me is that the device clearly reports both Celsius and Fahrenheit values:

• DP 2 (temp_current) = 23°C
• DP 6 (set_temper) = 18°C
• DP 3 (temp_current_f) = 73°F
• DP 18 (f_temper) = 64°F
• DP 10 (c_f_change) = false

Since c_f_change is false, I would expect Tuya Local to use the Celsius DPs (2 and 6), but the climate card is still displayed in Fahrenheit.

Am I missing something in the climate definition, or is there another place in Tuya Local that determines the temperature unit for a climate entity?

[make-all]

What tuya-local uses is irrelevant for what shows on a UI card. The UI is entirely based on the HA settings in /config/general (I thought it was per user, but apparently not for temperature unit)

[arkadiusz-odrowaz]

It works! 😊

What’s funny is that the global temperature unit setting was already set to Celsius. Out of desperation, I changed it to Fahrenheit, reloaded Home Assistant, then switched it back to Celsius — and now everything works correctly.

Thank you for the help!

By the way, the YAML configuration posted above is a working configuration for the Warmtec KP35W portable air conditioner, so hopefully it will save someone else some time if they come across the same issue.
