DO NOT BUY IT
An absolutely useless system. Installed throughout the entire house, 6 radiators, extra thermostat controller, and signal extenders( didin't really needed) and replaced to new Danfoss radiator valves( recommended by Wiser customer service) . This system is very inaccurate in result you have to cold or to hot house, resulting in a waste of money on extra heating costs in addition to the system itself. It's worth mentioning that it was installed by a certified plumber. The batteries run out very quickly; you'll need to replace them 3-4 times a year. The app is glitchy all the time. I deeply regret purchasing it; it's a waste of money and time. Now I have a completely useless system that I HAVE TO REMOVE and RETURN BACK TO THE OLD FASHIONED THERMOSTAT. I'VE LOST THOUSANDS OF POUNDS.
