Can you recommend any zigbee multizone thermostat? By thermostat I mean a device which can collect data from all zones and efficiently request heating from the boiler. It’s obvious it should be able to configure target temperatures in zones.
Thermostat should communicate with trvs using zigbee. Its communication with outer world (incl HA) should be zigbee or ethernet). Communication with boiler should be EMS-bus or OpenTherm.
Last week I spent seeking the Internet, but found nothing. There are tents of thermostats but very few of them are multizone.
I would do as much as possible to achieve this functionality by using dedicated hardware rather than making it diy way.
Thank you in advance
