Recommendations for WIFI Thermostats

hello,

so I’m having 10 zone controlled homematic wireless system using 868MHz to the Homematic HCU. I have lots of connection issues and keellp changing batteries. So I’m looking for an alternative.

I dont prefer to use zigbee as thats in the wifi band and that conflicts with our current wifi setups.

zwave is, as far i know, not a meshing protocol.

so I’m looking for energy grid supplied inwall thermostats on wifi that are supported by homey.

I’m capable of writing some code myself and advanced flows.

I know shelly has an integration in some room thermostats now, are all sensor properties available in homey?
