SonOff switch button with timer

[ricou27]

Hello,

I would like when I push the button to activate the SonOff contact, de-activate it after 1 sec. With the Sonoff_basic example, I tried to add some code to the "button_event_single_press" switch case like : switch_on.value.bool_value = !switch_on.value.bool_value; relay_write(switch_on.value.bool_value); homekit_characteristic_notify(&switch_on, switch_on.value); vTaskDelay(1000 / portTICK_PERIOD_MS); switch_on.value.bool_value = !switch_on.value.bool_value; relay_write(switch_on.value.bool_value); homekit_characteristic_notify(&switch_on, switch_on.value);

but impossible to do the job.

Have you an idea on how to do that

Thanks

You can not just do vTaskDelay inside button callback, you're blocking from inside interrupt which might mess up the whole OS.

Instead you need to set up a timer to switch your thing back. Check out lock example, where (if you set unlock_period setting) lock is opened only for small duration and then locked back.

Many thanks for your answer. That’s Work by using a timer. Regards
