Thanks stem, the zigbee thermostats are battery powered and will be controlled via home assistant which can then tell the hive to turn off / on as required. Regarding the wiring of the hive backplate am I correct above? This location is only used a couple of times a week for a couple of hours a...

Haven't seen any evidence of one. The cables coming through are 2 x t&e and 1 x 5 core of which 4 cores are used

Dual channel is the version I was going for, leaving the wired thermostats in place, but controlling via home assistant and zigbee thermostats as I have done at our other site. With the rads as heating channel and ufh as hot water. So to confirm, from my picture: leave out the loops to 2 and 5...
