What we like
- Receiver and room controller are included in one purchase
- Wireless sensor can measure from a useful room location
- No separate Bridge X is needed for the included Thread connection
- Can expand with Tado X radiator valves or a newer room sensor
What could be better
- First-generation EU kit is currently sold out at Tado
- Receiver still needs wiring and useful Wi-Fi at the heating equipment
- EU receiver is different from the UK hot-water programmer
- Automatic away control and other advanced features cost extra
The freedom to put the thermostat somewhere useful
The first-generation Wireless Smart Thermostat X kit is appealing when the best place to measure the room has no thermostat wire. Its receiver connects at the heating equipment, while the battery-powered room controller can be mounted in a useful living space. You get temperature buttons within reach and a reading that does not have to come from the old hallway position.
This is a practical reason to choose it over the wired model. If the existing wired thermostat is already in the right place, the extra receiver may bring little benefit. If you already have a working wireless Tado X kit, its ability to keep doing that job matters more than the newer generation's arrival.
A complete starting point, with a plain controller
The EU box combines a first-generation SU04 Wireless Temperature Sensor X and TR04 Wireless Receiver X. The sensor has a backlit LCD, physical buttons and three AAA batteries. It is ordinary-looking hardware, but replacement batteries and simple temperature controls are easy to understand.
The receiver also supplies the Thread border-router connection. That saves a separate Bridge X purchase, although unusually difficult coverage can still call for more infrastructure. “Wireless” refers to the link to the room controller: the receiver needs heating-system wiring and mains power, and connects to Wi-Fi at its installed location.
The kit covers the central heating control, not every room independently. Tado radiator valves or existing controlled zones are additional parts of a room-by-room system. The benefit is coordinating those rooms with the heat source, rather than merely collecting more temperature readings.
The discounted price needs available stock
On September 10, 2026, Tado's German store listed this kit at €149.99 instead of €199.99, but marked it sold out. Do not plan an installation around that price until an actual seller has the exact kit. It is a useful target for comparing remaining stock, not an available manufacturer bargain.
The second-generation EU wireless kit was available at €199.99. It keeps the TR04 receiver and replaces the room sensor with a rechargeable model, a light ring and a shortcut button. At the same full price, that newer controller is the more appealing purchase. A substantial discount makes this older kit worth considering, especially if you prefer ordinary AAA cells.
Do not substitute a UK listing just because it has a lower number. The British hot-water kit uses PR04 rather than the EU TR04 shown here. Its additional heating and hot-water controls must match the actual system; the versions are not interchangeable purchase labels.
The software is the longer-term decision
Free Tado schedules and remote temperature control provide useful basics. AI Assist adds automatic away adjustments, arrival preheating and other services, currently €3.99 monthly or €29.99 annually in Europe. The new hardware generation does not remove that subscription choice.
The room controller can share thermostat control with Matter apps. The receiver itself cannot be paired as an accessory, and domestic hot-water control is outside the current Matter integration. Keep Tado for its heating management and firmware connection rather than expecting every function in the preferred home app.
Buy this kit for a supported relay or OpenTherm installation when its available price makes the older controls good value. Keep it if already installed and comfortable. Replacing a functioning V3+ system deserves more thought: X cannot join the same Tado Home, and changing the whole system for a similar daily routine may be poor value.
