Here is how to reset the Tapo L535, from Tapo’s own guides. Start with a soft reset, which keeps your settings.

What This Problem Means

A reset clears a stuck connection. A factory reset also removes the Tapo L535 from your account, so you will need to set it up again.

Common Symptoms

• It will not reconnect after a router change
• Setup keeps failing
• You are giving it away or moving it

Safe Checks You Can Try

1. Factory reset in the app

Long-press the bulb’s card in the Tapo app and tap the minus sign.

2. Factory reset with the switch

Tapo says to power-cycle the bulb 10 times on Wi-Fi-only bulbs, or 5 times on Bluetooth models. The bulb blinks 3 times when it has reset.

3. Change Wi-Fi without resetting

Tapo says Bluetooth bulbs can switch to a new Wi-Fi network in the app: Device Setting > Network Connection > Switch Wi-Fi.

When To Contact Support

If none of these checks fix it, contact Tapo support through TP-Link’s UK support site, with the model and hardware version from the label on the device.
