Kasa KE100 Showing the Wrong Temperature? Here’s How to Fix It

Step-by-step fix guide | Kasa KE100

Try this first — Use Temperature Offset to correct the reading.

If the KE100 reads higher than the room, these points come from Tapo’s KE100 guide.

What This Problem Means

The valve measures the temperature next to the radiator, which can be warmer than the room.

Common Symptoms

  • The room feels cold but the app says it is warm
  • The heating turns off too early
  • Readings jump about

Safe Checks You Can Try

1. Use Temperature Offset

Tapo says if it reads 2°C high, set the offset to -2.

2. Add a Tapo sensor

Tapo says a T310 or T315 sensor bound to the same KH100 hub can correct the temperature.

3. Consider the KE110

The Kasa KE110 room thermostat regulates the valves from a reading in the room.

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.
