What is the tado° Smart Thermostat?
tado° is a smart heating control system designed to replace or upgrade a conventional wired room thermostat. It connects the home’s central heating system to the internet, enabling remote control, automated scheduling, and a range of sensor-driven features that adjust heating based on occupancy, location, weather, and environmental conditions.
Unlike some competitors — notably the Google Nest, which learns heating patterns autonomously over two weeks — tado° requires the user to manually programme a heating schedule through the app. This gives more precise control to households with consistent routines but requires more initial setup time and does not adapt automatically to changed patterns without manual reprogramming.
tado° is available as a wired thermostat or a wireless thermostat and can be extended with smart radiator thermostats (SRTs) for room-by-room control. The system works with virtually every combi, system, and regular boiler sold in the UK and is compatible with Google Assistant, Amazon Alexa, and Apple Siri voice control.
How Does the tado° Smart Thermostat Work?
tado° connects the radiator valves in the home to the central heating boiler through a central internet bridge (hub). The bridge connects to the home’s WiFi router, and the smart radiator thermostats connect to the bridge via Bluetooth. The tado° app on the user’s smartphone communicates with the bridge over the internet, providing remote control from anywhere with a data or WiFi connection.
When the app detects through GPS tracking that all registered household members have left the home, it signals the heating to reduce or switch to a frost protection mode. When it detects that a registered user is returning, it pre-heats the home to reach the target temperature by the time they arrive. This geofencing automation is the system’s most impactful energy-saving feature in typical household use.
The smart radiator thermostats measure both temperature and humidity at each radiator and report this data to the app, allowing both remote monitoring and individual room control. The hub sends heating demand signals to the boiler based on the aggregate of the room targets and the current measured temperatures.
Key Features
Geofencing
Geofencing uses the GPS location data from the smartphones of registered household members to determine when the property is occupied and when it is empty. When the last registered occupant leaves a defined geographic zone around the property, tado° automatically reduces heating to save energy. When the first registered occupant’s phone shows they are returning, heating restarts automatically so the home is at the target temperature on arrival.
Geofencing is tado°’s most distinctive feature relative to schedule-based thermostats. A schedule-based system heats an empty home whenever the schedule calls for heat — geofencing eliminates this waste on days when occupants leave or return at different times to their programmed schedule. Access to geofencing requires the Auto-Assist subscription — the feature is visible in the free version but automated activation requires the paid tier.
Weather Adaptation
tado° connects to external weather forecast data and adjusts the heating system’s output based on predicted outdoor temperature changes. Rather than waiting for the indoor temperature to drop and then reacting, weather adaptation pre-adjusts heating to compensate for incoming cold weather — maintaining consistent indoor comfort with less reactive cycling of the boiler.
Open Window Detection
The smart radiator thermostats’ temperature and humidity sensors detect a sudden simultaneous drop in both readings — the signature of an opened window — and automatically pause heating in that room to avoid wasting energy heating air that is immediately lost to the outside. When the window is detected as closed — temperature and humidity stabilise — heating resumes automatically.
Open window detection is available as a manual notification in the free app version. Automatic heating pause and resume requires the Auto-Assist subscription.
Room-by-Room Control
Each smart radiator thermostat controls the individual radiator valve it is fitted to, allowing different target temperatures in different rooms simultaneously. A home office can be kept warmer during working hours while unoccupied bedrooms remain at a lower background temperature. Guest rooms can be heated only when occupied without affecting the rest of the house.
Room-by-room control requires a smart radiator thermostat on each radiator to be independently controlled. The starter kit includes the central thermostat and bridge — smart radiator thermostats are purchased additionally for each room requiring individual control.
Air Comfort
The humidity and temperature sensors in each smart radiator thermostat feed into tado°’s Air Comfort mode, which monitors indoor air quality and provides recommendations through the app. Unusually high humidity is flagged as a ventilation recommendation. Outdoor air quality data — including pollen count, pollution levels, and temperature — is also presented in the app alongside indoor readings, allowing informed decisions about ventilation.
Smart Scheduling
tado°’s scheduling system allows the user to programme heating periods for each room individually by time block and day of the week. A typical setup programmes higher temperatures during morning and evening occupation periods and lower temperatures during working hours, overnight, and at other low-occupancy periods. The schedule is set manually through the app — there is no self-learning function as in the Google Nest — and must be reprogrammed manually if household routines change significantly.
One limitation noted during testing is the absence of a schedule duplication function between rooms. Where multiple rooms require the same schedule, each must be programmed individually — a time-consuming aspect of the initial setup for homes with many radiator thermostats.
Voice Control
tado° is compatible with Amazon Alexa and Google Assistant for full voice control including individual room temperature adjustment. Apple Siri compatibility is available but limited to turning the heating on and off — room-specific temperature adjustment is not supported through Siri. Voice control is available without subscription through the standard app.
Hot Water Control
The tado° Wireless Thermostat Starter Kit with Hot Water Control extends app-based control to the domestic hot water cylinder, allowing the user to schedule hot water heating periods and control the cylinder temperature independently of the space heating schedule. This is relevant for system and regular boiler installations where a separate hot water cylinder is present. The hot water control extension is an additional purchase beyond the standard thermostat starter kit.
Auto-Updates
tado° firmware updates are delivered automatically over the internet — the system updates itself without any user action required. This ensures the system continues to receive performance improvements and new features without manual intervention.
Design
Both wired and wireless iterations of the tado° thermostat use a clean white square design that sits discreetly against a standard wall without dominating the room. The display is subtly backlit and easy to read in normal lighting conditions. The smart radiator thermostats take a modern approach to the conventional TRV design — a cylindrical white unit with a digital temperature display that replaces the standard numbered valve head.
The overall aesthetic is consistent and understated — considerably more visually refined than the older generation of programmer and thermostat combinations that tado° typically replaces. The physical controls are minimal, reflecting the expectation that the app handles most interaction, though basic temperature adjustment is available directly on the thermostat and radiator valve units for users who prefer not to use the app for routine changes.
tado° App Review
The tado° app is comprehensive and well-designed, providing access to the full feature set in a single interface. Home screen widgets show current temperatures and heating status for each room at a glance. The scheduling interface allows detailed programming by time block. The air comfort section provides indoor and outdoor environmental data clearly. Smart reporting shows historical temperature data, heating usage, and estimated energy savings over time.
The app is slightly less immediately intuitive than some competitors — the Hive app, for example, has a shallower learning curve for new users — but the depth of control it provides justifies the modest initial familiarisation time. Most users report becoming comfortable with the full feature set within the first week of use.
The app is available for iOS and Android and can be downloaded from the App Store and Google Play. Multiple users can be registered on a single account, enabling all household members’ locations to contribute to the geofencing function.
Pros and Cons
The tado° system’s strengths are its geofencing capability, room-by-room control, weather adaptation, and the depth of its app’s monitoring and control features. The smart radiator valve design is one of the most refined in the market. Compatibility with virtually every UK boiler and all major voice assistant platforms makes it one of the most universally applicable smart thermostat systems available.
The limitations are meaningful for budget-conscious buyers. Geofencing and open window detection — two of the system’s most marketed features — require the Auto-Assist subscription to operate automatically. Without the subscription, these features provide manual notifications only, significantly reducing their energy-saving impact. The hot water control extension adds meaningful cost for system boiler users. Smart radiator thermostats, at approximately £50 to £70 each, represent a significant additional investment for homes with many radiators. The battery requirement of the radiator thermostats — AA batteries rather than mains power — means periodic replacement is needed.
The absence of a self-learning function means tado° does not adapt to changed household routines automatically — this requires manual schedule reprogramming. Households with highly variable schedules may find the Google Nest’s self-learning capability more practically convenient.

Installation and Setup
tado° installation involves replacing the existing room thermostat wiring at the boiler’s wiring centre or programmer, mounting the internet bridge near the home’s WiFi router, and fitting the smart radiator thermostats in place of the existing TRV heads on each radiator. The manufacturer provides clear instructions and the physical installation is manageable for a competent DIYer with basic tools.
However, the boiler wiring connection constitutes Part P notifiable electrical work on the fixed installation, and engaging a Gas Safe heating engineer for the wiring element ensures correct installation and compliance. Many heating engineers install tado° systems routinely and the total professional installation time is typically one to three hours depending on the number of radiator thermostats.
App setup after hardware installation — allocating each radiator thermostat to its room, programming the initial schedule, and registering all household members for geofencing — takes approximately one to two hours for a thorough initial configuration.
