If the KE100 keeps dropping offline, these are the checks from Tapo’s KE100 guide.

What This Problem Means

The valve keeps losing its link to the KH100 hub.

Common Symptoms

• Offline in the Kasa app
• Schedules seem to stop
• The temperature is not updating

Safe Checks You Can Try

1. Update everything

Tapo says to update the hub, the valve and the Kasa app.

2. Move the hub closer

Move the KH100 closer to the valve.

3. Know what still works

Tapo says schedules run without internet while the hub is working, and the manual knob works offline.

4. Check the batteries

Replace the batteries if the low-battery icon shows.

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.
