|---|---|---|
| Devices and connectivity | Wired or wireless X setup; Matter and Thread with a suitable border router | Wired or wireless V3+ setup with its Internet Bridge |

BEFORE YOU CHOOSE
Will it work in your home?
The boiler model, control protocol, hot water cylinder, valves and heating zones all matter. Existing V3+ devices cannot be retained as X devices in the same Home. Professional checks are especially useful for S-Plan, Y-Plan and wet underfloor heating.
Check compatibility, use the thermostat picker or ask us about your system.
Benefits and trade-offs
Tado X Gen 2
Matter and Thread connectivity, the updated white thermostat and compatibility with existing X devices suit an X-family installation.
Check the border router, boiler protocol and kit. X cannot share a tado Home with V3+ devices, optional automation uses AI Assist, and X has no equivalent V3+ scheduled Early Start setting.
Tado V3+
V3+ can extend a compatible existing V3+ installation. Scheduled Early Start can help slow wet underfloor heating reach its target at the planned time.
V3+ uses its older communication system rather than X’s Matter and Thread setup. Some automation uses Auto-Assist. Check the exact product’s availability and boiler compatibility.

A FEW THINGS TO KNOW
Questions before switching
Can I add Gen 2 to existing Tado X?
Yes, Gen 2 works within the X family. Check the kit and border router for the installation.
Can I add X to my V3+ Home?
No. X and V3+ use different communication systems and cannot share the same tado Home.
Does X Gen 2 need a subscription?
App control and schedules do not require AI Assist. Some extra automation does; check current tado terms.
What should I check for underfloor heating?
V3+ scheduled Early Start can pre-warm to reach a target at the scheduled time. X’s arrival-based Preheat Before Arrival does not replace that setting.
