Kasa KE110 Not Controlling the Radiators? Here’s How to Fix It

Step-by-step fix guide | Kasa KE110

Try this first — Check the KE110 is linked to the right valves in the Kasa app.

If the KE110 is not changing your radiators, these points come from TP-Link’s KE110 guide.

What This Problem Means

The thermostat is not passing its setting to the valves.

Common Symptoms

  • The valves ignore the KE110
  • Rooms stay cold
  • Changes on the KE110 do nothing

Safe Checks You Can Try

1. Know how it works

TP-Link says the KE110 controls linked Kasa radiator valves by setting their target temperature. TP-Link does not say it switches a boiler.

2. Check the link

Press SYNC twice: the hub sounds if the connection is good. If not, move the KE110 closer to the hub.

3. Check the valves

Make sure each KE100 is online in the Kasa app.

When To Contact Support

If none of these checks fix it, contact TP-Link support through TP-Link’s UK support site. Have your KE100 or KE110 and KH100 hub model numbers ready.
