Hello all,
The last three years I’ve bought a small number of smart heating thermostats: 2x Homematic IP Basic, 4x Homematic IP Standard and a small access point for controlling them via Cloud.
They are working without any problems but then I’ve started to use Home Assistant and It would be great to controll my thermostats via Home Assistant as well. The Homematic IP has some limitations and setting an RaspberryMatic (+including it in HS) is a pain, so what’s next?
Right: I would like to extent my Zigbee Network with some smart heating thermostats.
There a many many different models, but the best knowledge have the users 
Do you have and recommendations for Zigbee based Thermostats which are silent while setting up the temperature?
For example, the Homematic Basic one is not useable in a bedroom because its loudness.
