Awenta AHR 160 Integration

Hello,
About a year ago I got installed Awenta AHR 160 recuperation units. They have WiFi and come with separate bluetooth temperature and humidity sensors.
I tried finding a way to get them work with HA but found no avaliable integrations.
I even wrote to manufacturer for their support of API but never got any response from them.

So I took my time and reverse engineer it. So for everybody who is looking for it here it is:

It’s cloud push for now, but I’m hoping to get some local thing working.

Best regards, MK
