For years, my home has been heated using Honeywell Evohome with 16 radiator thermostat knobs. It worked reliably, but the interface was dated and adjustments were never intuitive. When tado° asked me to test their new tado° X smart heating system, I decided to fully replace my Evohome setup and see how it compares—especially with Home Assistant and Matter support.

Hardware Overview
The tado° X system consists of:
- Wireless Receiver X (connected to your boiler)
- Radiator Thermostat X knobs
- Wireless Temperature Sensor X (optional, ideal for large rooms)
All devices support Matter, making them easy to integrate into smart home platforms like Home Assistant.
The thermostat knobs feature:
- A premium matte display
- Rechargeable USB-C batteries (up to 1 year)
- Local schedules that work even without internet
Installation Experience
Installing the Wireless Receiver X took about 15 minutes. The tado° app guides you step by step, whether you have an OpenTherm boiler or a simple on/off setup.
Radiator thermostat installation was straightforward. Each knob includes adapters for nearly every radiator valve. Pairing is done via QR codes, and each device is assigned to a room in the app.
The Wireless Temperature Sensor is perfect for rooms with multiple radiators, ensuring consistent heating based on a central temperature reading.
tado° App & Features
The tado° app focuses on simplicity:
- Room-based temperature control
- Weekly schedules per room
- Temperature & humidity history
- Energy usage insights (Energy IQ)
Some advanced features like geofencing and open window detection require the Auto-Assist subscription, but notifications still work without it.
Home Assistant & Matter Integration
tado° X shines when combined with Home Assistant.
Using Matter, each thermostat knob can be:
- Added individually
- Controlled directly
- Used in automations
This allows you to:
- Create subscription-free geofencing
- Lower heating automatically when doors or windows open
- Build advanced heating logic using sensors and presence detection
Compared to the legacy tado° integration, Matter support is far more powerful.
Heating Performance
tado° X heats rooms more gradually than Honeywell Evohome. While Evohome often heats aggressively, tado° X ramps up slowly and steadily. After a short adjustment period, my home feels more comfortable—and I expect lower gas usage over time.
Schedules are stored locally, so heating continues even without an internet connection.
Pricing
- Wireless Smart Thermostat X: €199.99 (includes temp sensor)
- Radiator Thermostat X: €99.99 each (discounts for multi-packs)
- Auto-Assist subscription: €3.99/month or €29.99/year (optional)
Final Verdict
The tado° X system is:
- More modern and better designed than Honeywell Evohome
- Easier to use and configure
- More powerful when combined with Home Assistant
If you care about design, usability, and Matter support, tado° X is an excellent choice. If you prefer a one-time purchase without subscriptions and don’t mind a dated UI, Honeywell Evohome still works—but feels outdated in comparison.
With Home Assistant, you can unlock the full potential of tado° X without subscriptions, making it my preferred smart heating solution going forward.
