I have a Secure SSR302 boiler control unit. This has two channel’s, one for the heating and the other for the hot water. Associated via ZWave I have two Secure SRT321’s, one in the Living Room (Master) and one on the first floor landing. So adjusting either thermostat by hand will switch the heating channel on the boiler control unit. This the basic setup and allows me to control my heating without the need of any OH rules. Each radiator has a Danfoss LC-13 installed to replace the mechanical TRV’s.
Presently I have grouped together a number of radiators and manage their setpoints via a number of rules within OH. So depending on the time of day and season I change the setpoint to an appropriate level. I would say that this is quite a basic setup but is a good starting point for myself. As all of the components are ZWave and battery operated I need to balance out battery life verses function, which means I have to compromise a little.
I hope that helps a little more @domofl
