Fahrenheit/Celsius
Hi everyone,
Unfortunately, there is a bug in HA Core 7.1. The Tuya app works without issues with HA Core 6.4 for my air conditioners; HA displays 20 degrees Celsius there. After updating from 6.4 to 7.1, it displays -6.7 degrees Celsius. It seems HA Core 7.1 performs the calculation differently. 20 Fahrenheit is exactly -6.7 degrees Celsius. I’ve reverted to Core 6.4, where it works fine.

Perhaps a developer could take a look at this.
Many thanks,
Bernd

Which Tuya integration?

There are at least three I know of.

Tuya Cloud (core)
Tuya Local (3rd party)
Local Tuya (3rd party)

Tuya Cloud (core), added via integration

In that case you can report the issue here:

But only after checking that there is not already an open issue for it.

There are 2 issues reported about this already. Go put a thumbs up (don’t say “me too”) on both of these:

The Tuya Smart app still displays the correct target temperature (for example 19°C), but Home Assistant now reports an incorrect target temperature. Example: * Tuya app target temperature: **19°C** * Home Assistant `temperature`: **-7.2°C** * Home Assistant `current_temperature`: **28°C** (correct) The current room temperature is reported correctly, only the target temperature is wrong. ### Diagnostics The diagnostics show: Current status: ``` temp_set = 190 temp_current = 28 ``` The value `190` clearly represents **19.0°C**. However, the diagnostics also show that the current metadata defines: ``` temp_set unit = °F min = 160 max = 880 scale = 1 step = 5 ``` while `original_function` still contains: ``` temp_set -> °C temp_set_f -> °F ``` This suggests that Tuya changed the metadata for this product, but the reported value is still in Celsius. As a result, Home Assistant interprets the target temperature incorrectly. ### Additional information * The issue is **not** caused by a recent Home Assistant update. * I restored a backup from before the problem started. * I re-authenticated the Tuya integration. * The issue remains exactly the same. * The Tuya Smart application always shows the correct temperature. I have attached the diagnostics file.

### The problem ### The problem After upgrading to Home Assistant 2026.7.0, my… Tuya air conditioner reports an incorrect target temperature. The device itself is working correctly and the Tuya Smart app also shows the correct target temperature. Example: Target temperature set on device: 21.0°C Tuya diagnostics: temp_set = 210 Home Assistant climate entity: temperature = -6.1°C The current temperature is reported correctly. This appears to be a conversion problem inside the Tuya climate integration. ### What version of Home Assistant Core has the issue? 2026.7.0 ### What was the last working version of Home Assistant Core? Home Assistant OS ### What type of installation are you running? Home Assistant Core ### Integration causing the issue Tuya ### Link to integration documentation on our website _No response_ ### Diagnostics information [tuya-01KQ8545SQZY5PYDE5ZZCMC5RW-Klimaanlage-624b69cd781099f5cbb1df48f1a615cd.json](https://github.com/user-attachments/files/29653008/tuya-01KQ8545SQZY5PYDE5ZZCMC5RW-Klimaanlage-624b69cd781099f5cbb1df48f1a615cd.json) ### Example YAML snippet ```yaml ``` ### Anything in the logs that might be useful for us? ```txt ``` ### Additional information temperature should report 21.0°C temperature reports -6.1°C status: temp_set: 210 temp_current: 22 mode: cold current_temperature: 22 temperature: -6.1 The diagnostics also show that the original device definition uses Celsius for temp_set, while the active strategy appears to interpret it as Fahrenheit, resulting in an incorrect conversion.
