Beginner, help!
I have successfully flashed OpenBK on a 2-channel Tuya relay module, can address the relays, the local buttons work, great so far. Now I want the relays to drop out again after 1 sec after pressing ("inching"), the "Tuya" firmware was able to do this by default. I found an autoexe code snippet in the documentation ( /turn_off_relay_after_time.bat), which works great for CH1, but I can't get the few lines extended so that both relay channels drop out after one second.
Maybe someone can extend the code correctly?
Thank you

The backlog allows you to execute several commands, such as setting both channels to zero.
Code: text Expand Select all Copy to clipboard
alias turn_off backlog setChannel 1 0; setChannel 2 0 // This aliased command will turn off relay on CH1 after 10 seconds // addRepeatingEvent [IntervalSeconds][RepeatsOr-1][CommandToRun] alias turn_off_after_time addRepeatingEvent 10 1 turn_off // this will run the turn off command every time that CH1 becomes 1 addChangeHandler Channel1 == 1 turn_off_after_time addChangeHandler Channel2 == 1 turn_off_after_time
.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
