Unfortunately the update didn’t work for me. One unit is working fine, the other one still isn’t working.

I was wondering if there is a difference between both units so, I took both units and wifi modules apart. And there indeed is a difference between both wifi modules.

Wifi Modules:

- Model: BL3332-P (Ver: 52010) ← This ons is working

- Model: BL3372-P\_1v1 (Ver: 62025) ← this one is not working

To make sure the wifi module indeed is the issue, I switches them around. The result was that the airco that had the BL3332-P module installed worked fine, but the unit with the BL3372-P\_1v1 module installed didn’t work. So, the “issue” indeed seems to be the wifi module.

fyi: Both wifi units work fine in the M-air app, but Homey keeps giving the "device unavailable” error with the BL3372-P\_1v1 module.

@evdpol or anybody else any thoughts?
