The Meross MTS200 is the top pick: the cheapest wall-mounted smart thermostat here at under $120, carrying 4.4 stars across more than 2,700 reviews with HomeKit, Alexa and Google Assistant support, and it suits hydronic, gas-boiler and electric underfloor setups. The Inkbird ITC-308 WiFi is the budget winner, because it plugs straight into a power point and controls any portable heater or cooler without touching your wiring. The Google Nest Thermostat is the one to look at if you have a 24V ducted or gas central system and want the Google Home app.
