Good morning,I have a dual zone heating system in a four year old house. I have one thermostat on the ground floor and another on the second floor (controlling the first floor radiators too). I want to install smart thermostats I can control from my smartphone.Am I right in thinking I need two thermostats still? Can you recommend a product that works together and is easy to operate both heating zones via an app.Many thanks. via /r/DIY https://ift.tt/2PMJl55
