Heating Control

I’m looking at integrating my heating into ST. At moment we have a wireless Climapro RF2 thermostat from Glowworm. Their smarthome offering is MiGo, but am pretty sure it is not ST compatible.

I would also like eTRV so i can set simple zones within the house. I’ve looked at honeywell evo home but it is more than i would like to pay at the moment, considering the number of eTRV’s I would need.

I like the look of nest, but am unsure how it would work with the eTRV’s. Does anyone have a Nest and eTRV’s. Any feedback would be welcome
