First-time poster here. I have been following SuperHouse for a while now. I’m trying to automate my central heating/cooling system (York) ) by replacing my old thermostat. I was just wondering what options are there that can support zones. I have looked at Nest and Ecobee, but not sure if they can support zones without major rewiring. At the moment I have manual switch that changes zones to upstairs / downstairs. I have attached a few pictures of my controller wiring. Thank you for your help.
