TP-Link KE100 unavailable if heating and low battery

[karl-the-llama]

The problem

I just installed the TP-Link Smart Home integration because of the added support for the Kasa KE100 thermostat. I only installed it in core 2024.7.1 . My first test was to set one thermostat to heat which made it unavailable. It was a thermostat with low battery. When I switched it off outside HA it immediately became available again. My two other KE100s with full battery are not affected. The log says there are 2 states (heating, low bat) and that it chose low battery.

What version of Home Assistant Core has the issue?

Thanks for the report & the logs! This will require changes to the upstream library to handle this correctly, so I added a label for it.

Fixed by #121791 so this should work with 2024.7.3 when it's released.
