tado° Thermostat X: Trio Pack: what works and what doesn't
What works well
- Demonstrable savings: according to tado° 22% less heating energy on average, the more rooms, the bigger the effect
- Window detection without a sensor: detects opened windows entirely without additional contacts, less hardware, lower costs
- Touch display on the device: direct operation without a smartphone, plus app and voice control via Alexa, Google and Siri
- Battery instead of batteries: the removable battery charges via USB-C in around 2 hours and only needs the cable once per season
- Trio Pack saves money: three thermostats in a set are cheaper per piece than buying singly, a good start for several rooms
Points of criticism
- Bridge X not included: for Matter and Thread you need the separate Bridge X or another Thread router, extra cost
- AI savings function costs: the full savings of up to 55% are only available with the AI Assist subscription (€3.99/month or €29.99/year)
- Not backward compatible: tado° X is not compatible with tado° V3+ or older, a system change for existing users
