I have four Mysa v1 thermostats intergated into HA. In pairs, two Mysa share/control the same AC unit.
Split AC units have requirement: the demand for heating/cooling coming from the thermostats need to be the same - both cooling or both heating - otherwise the AC will stop working.
The following feature request can be achieved via automation!
Feature request:
- ability to link a set of thermostats together so that the AC mode becomes a common setting.
