Sonoff TRVZB calibration not available?

[swazrgb]

I expected being able to configure the calibration of my Sonoff TRVZB since I've seen PRs mentioning this functionality:

#304
#300

Which seem to be part of this release: https://github.com/zigpy/zha/releases/tag/0.0.40

But it doesn't seem available:

Am I missing something?

Running Home Assistant 2025.1.4 with zha==0.0.45

When you click on the three dots on the left, "Manage Zigbee Device", then select the "Thermostat" cluster and the "local_temperature_calibration" attribute, what response do you get in the field below after pressing "Read Zigbee attribute"? Is it 0 or None?

If it's 0, then you can restart HA and the entity will appear. This attribute should have been read during pairing though.

If it's None, then we have an issue. We might need to ignore if a value exists in the attribute cache for this entity and always create it if the attribute is not marked as "unsupported".
But in this case, you can set it to 0 (replace None with 0 in the upper text field, leave lower field empty) and click "Write Zigbee attribute". Verify the attribute now reads 0. You can restart HA then and the entity will show up properly.
