IFA: Tado's second X-series smart wall thermostat is thinner and charges via USB-C

Tado, a German manufacturer of smart home devices, has unveiled the second generation of its X-Series wall thermostat at the International Fair of Electronics, Information and Communication Technology (IFA). The new model is thinner than its predecessor, features a white finish instead of the previous black-and-white design, and uses a built-in battery charged via a USB-C port. The device was originally introduced in 2024 and has now been refined after two years of development. The updated thermostat measures just 17.8 millimeters in thickness, making it nearly four millimeters thinner than the original version. Its sleek, all-white casing allows it to blend more seamlessly into modern interiors. A circular LED display replaces the previous button-based interface, allowing users to adjust temperature with a swipe gesture rather than physical buttons. Additionally, a dedicated button on the top edge offers quick access to three functions, displaying room humidity, resuming heating schedules, or boosting heating for 30 minutes, which can be customized through the Tado app. Instead of relying on disposable batteries, the new thermostat is powered by an integrated rechargeable battery. Users can charge it using a USB-C port located on the housing. According to Tado, the battery should last up to one year without requiring a recharge. Although the battery is permanently installed, it can be replaced with tools in case of wear or malfunction. The second-generation thermostat is compatible with a variety of heating systems, including gas boilers, heat pumps, and underfloor heating. It comes in both wireless and wired versions. The wireless variant connects to a boiler via a radio adapter, while the wired version includes a built-in battery and does not require connection to the household electrical grid. Alongside the wall thermostat, Tado has also upgraded its X-Series wireless temperature sensor. Like the thermostat, the sensor now features a thin, white housing and a touch-sensitive interface with an LED ring. This allows it to measure temperature at specific points within a room, improving the accuracy of regulation for Tado’s first-generation radiator thermostats. Both the thermostat and sensor operate via Thread technology and support integration with Matter-compatible smart home ecosystems. The new products are available for purchase immediately. The wired wall thermostat costs €120, or €180 when bundled with a Thread Border Router from Tado's X-Series. The wireless version, which includes a radio adapter for the boiler, is priced at €200. The second-generation temperature sensor is available for €100. To encourage purchases, Tado has introduced a money-back guarantee. If customers are not satisfied with their energy savings within 12 months of purchase, the company will refund the product cost. However, the exact criteria for determining satisfaction remain unspecified. For full functionality, users still need to subscribe to a paid service plan costing €4 per month or €30 annually. The subscription includes geofencing capabilities, automatic heating shutdown when windows are open, and hydraulic balancing.
