WiFiXpert Compatibility Score — tado° smart thermostat

The bridge plugs into your router, so heating carries on even when Wi-Fi is having a bad day.

What we checkRatingPoints

Works on 2.4 GHz

The bridge is wired; radiator valves use their own low-power radio.

Not needed for the bridge14/14

Works on 5 GHz

No Wi-Fi involved for the bridge.

Not needed10/14

Modern Wi-Fi security

A cable sidesteps Wi-Fi security mismatches entirely.

Excellent11/12

Happy on mesh Wi-Fi

Nothing roams, so mesh changes rarely affect it.

Very good13/16

Works on a guest network

Control runs through tado°'s servers.

Not affected6/8

Survives a plug-in extender

Extenders make no difference to a wired bridge.

Unaffected7/8

Doesn't depend on chatty discovery

Doesn't rely on chatty local messages day to day.

Low dependency13/16

Easy to fix when it goes wrong

The bridge light tells you plainly whether it's the internet or the heating.

What usually goes wrong

App says the heating is offline, usually right after a new router arrives.

Free things to try, in this order

  1. 1

    Check the bridge is still plugged into the new router.

  2. 2

    Restart the bridge by unplugging it for 30 seconds.

  3. 3

    The heating keeps to its schedule offline — you're not left cold while you sort it.

Before you buy anything

Not a Wi-Fi spend. If the valves lose the bridge, move the bridge nearer the middle of the house.

Answers about this gadget

What it needs from your network

Wall-mounted 2.4 GHz client in a fixed position, often behind a plasterboard wall with foil insulation.

Bands it uses
2.4 GHz only on most models. It will not see a Wi-Fi name that is 5 GHz only, and setup fails silently if your phone is on the 5 GHz half of a split network.
How it's found
Cloud-based, so router filtering is rarely the issue. Position almost always is.
Background discovery traffic
Low.
On a guest network
Setup fails.
On a separate gadget network
Fine on an IoT network.

Getting it set up

  • Hold it near the router during setup if it detaches from its mount.
  • Check the signal reading before you refit it to the wall.
  • Stand next to your router while you set it up, then move the gadget to where it lives.
  • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
  • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
  • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.

With mesh Wi-Fi

  • Once mounted, it cannot roam. If you add mesh, restart the thermostat so it picks the nearest box.
