Countdown on each on

Hello everyone,


I have device that need to run for 4hours from the moment it has been turned on. Can it be done with Sonoff basic and EWeLink?


Loop timer runs in background and when i turn on device i am entering the loop not from beginning.


Countdown timer has to be enabled each time manually. Any idea?

This would also be very helpful for controlling roller blinds. To automatic turn off the switch after about 20 seconds. Such a feature should be implemented to cover Hour, Minutes and Seconds triggered automatically when the switch is turned on.

 This is how to do this.

set loop timer restart cycle 4h OFF

Unselect After

Then complete

Tor's comments above are correct. This function works great for me.


I can confirm that both the new inching function in firmware 2.6 as well as the loop timer as detailed by martin in a different thread BOTH work as a countdown timer based on when my device is switched to on.


Inching has a max time of 1 hour, the loop timer can go for longer. Both work great on my sonoff basic switches. I use it currently in several locations to turn off the piano after an hour, turn off a humidifier after 45 minutes, turn off a table fan after 2 hours.


I love it!
