The Warmup 7iE Smart Matter WiFi Thermostat is the world's first floor heating thermostat with native Matter protocol support — giving you effortless, one-platform control across Apple Home, Google Home, and Amazon Alexa without workarounds or bridges. Available here in Onyx Black with Dark Chrome trim, the 7iE combines a premium full-colour touchscreen, SmartGeo location-aware intelligence, and Warmup's exclusive Smartcare remote diagnostics service in a ultra-slim profile that sits just 16 mm from the wall. Compatible with electric underfloor heating, hydronic UFH, and central heating systems.
The 7iE is the first floor heating thermostat with native Matter support, connecting directly to Apple Home, Google Home, and Amazon Alexa from a single, universal protocol. Control your heating by voice, set cross-device automations, and manage everything from one app — no proprietary bridge required.
SmartGeo uses your smartphone's location to learn your daily routines automatically. It lowers the temperature when you leave and ensures your floor is at the perfect warmth by the time you return — delivering up to 25% reduction in energy usage with zero effort or programming required.
Owners of the 7iE gain exclusive access to Smartcare, Warmup's proactive heating support service. Using live data from the thermostat, Smartcare monitors system performance remotely and delivers instant expert technical support — resolving most heating issues without a site visit.
After mounting, simply scan the QR code on the 7iE screen with the MyHeating app to complete setup in minutes. The app provides full remote control — adjust temperature, view energy use, set programmes, and enable SmartGeo — from iOS or Android, anywhere in the world.
The built-in Energy Monitor tracks consumption over the last 24 hours, 7 days, and 30 days. It multiplies system power by efficiency and run time to give you an accurate picture of how much energy your heating is using — and where savings can be made.
Adaptive Learning analyses historic heating rates and external temperature forecasts to calculate the optimal start time — so your floor reaches comfort temperature exactly when you need it. Open Window Detection automatically pauses heating when a sudden temperature drop is sensed, saving energy.
The premium colour touchscreen shows the current floor or air temperature, target temperature, heating status, a 7-day weather forecast, and time — all at a glance. Customise the background image, standby style (temperature, time, or minimalist), and brightness for active, standby, and night modes.
Ships with a 3 m NTC 10K floor sensor (extendable to 50 m). The 7iE supports dual-sensor operation — floor control with air limit, air control with floor limit, or regulator mode — covering all electric UFH, hydronic, and central heating applications from one device.
The 7iE is fully compliant with EcoDesign Regulation (EU) 2024/1103 and Directive 2014/53/EU (RED), and is manufactured by Warmup — a company aligned with the UN Race to Zero initiative. It carries an ErP Class IV energy efficiency rating.
Up to 6 periods per day, individually programmable per day or as weekday/weekend blocks. Setback and sleep temperatures apply outside comfort periods.
Fixed target temperature maintained until another mode is selected. Ideal for holiday lets or rooms with irregular use.
Override the schedule with a lower temperature over a defined date range to save energy while you're away.
Maintains a minimum 7 °C floor or air temperature to protect the building and floor structure when heating is otherwise off.
Location-aware automatic mode. Reduces temperature on departure, restores comfort temperature on approach home.
