Daikin Integration - temperature setting is missing when switching mode from "Fan Only" to "Heat/Cool"

[chiahsing]

The problem

Temperature setting is missing when switching mode directly from "Fan Only" to "Heat/Cool". Switching from "Fan Only" to "Cool" to "Heat/Cool" is fine as the temperature setting is restored when switching to "Cool".

What version of Home Assistant Core has the issue?

core-2024.9.1

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?

Home Assistant Container

Integration causing the issue

daikin

Link to integration documentation on our website

Diagnostics information

When the climate device is in fan only mode, there is no temperature setting (because it only actives the fan). When switching from fan only to cool, the temperature setting should be restored, and is restored. When switching from fan only to heat/cool (auto mode), the temperate setting should have been restored, but is not.

This sounds like a frontend issue. Is the behavior as expected using the set climate action?

[chiahsing]

Using climate.set_hvac_mode still shows the same behavior.

When I switch from heat/cool to fan_only, the temperature still exists in the attribute and has the previous value (e.g. 25). When I call climate.set_hvac_mode to set it to "Heat/Cool", the temperature attribute becomes "null".

[chiahsing]

And when switching to "heat/cool" without temeperature, it falls back to "fan_only" mode after a few seconds. It seems that the integration fails to set the mode, and the integration picks up the mode from the wifi module and orverrides its own inconsistent state (just my guess. I have no knowledge of how this integration works.)

[fredrike]

Which part of the integration are you running? Do you pass password/API-key?

[chiahsing]

It's a BRP072C42 that needs an API-key.

I'll have a look in the underlaying library https://github.com/fredrike/pydaikin. It might be a simple solution.

It would be great if you could open an issue there and provide some more logging.

Thanks! Filed fredrike/pydaikin#31
