Utilize the app to set various timers to automate your lighting:
- Inching Time: Turn on for a set duration (e.g., 1 minute), then automatically turn off.
- Countdown: Turn off after a specified countdown (e.g., 10 minutes).
- Circulate Timing: Set lights to turn on and off at specific times daily (e.g., turn on at 18:30, turn off at 22:00 every day).
6.5 Relay Status Setting
Configure the module's behavior after a power restart:
- On: Light turns on after power is restored.
- Off: Light remains off after power is restored.
- Remember Last Status: Light returns to its state before the power outage.
Tip: If the internet connection restarts, the device may also need to be restarted manually to re-establish connection.
7. Maintenance
