Great work! Thank you. I will use this version till next official release:)

One other sensor is missing... HUW temperature....
You can see SET temperature but not actual

Its "tempCWU"

So need to go back to beta version because of this sensor missing:(

But big thanks for your support. Great work

Also noticed that sensor updates on beta version 1.03 are wayyy better than on dev version...

That might be the case, but I had to rewrite everything and clean up the old unused code. This was necessary because there are many devices with different versions. Now, it will be more flexible to continue working. Apologies for any inconvenience caused.
