To use the schedule feature of the smart light bulb, you will need to configure this device to Tapo App first.
How to set up Tapo smart bulb
The XXXX in the smart bulb WiFi "Tapo_Bulb_XXXX" is the last four digits of its device Mac address, which can be found on the product label on the package box.
If you have bought multiple smart bulbs but fail to locate the correct WiFi for each light bulb during the setup, turn to power and setup on one device at a time, instead of turning on all the light bulbs.
