Description

I use mushroom cards on my dashboard to control BT. Turning off the thermostat works, but turning it on throws an error. On 1.5.0-beta5 it works fine, but after an upgrade to 1.5.0-beta6 or higher this error appears.

I have noticed the same problem on my setup today.

From a quick code inspection, it seems the issue has been introduced by a recent commit (b53b564) which was bundled into BT version 1.5.0beta6.

I have found the root cause and successfully tested it on my HA instance. I've also raised a PR to fix the issue:
#1323

@KartoffelToby , do you mind approving and merging it? It's a very short one.

My 2 cents
