Help with melphaa script

[miguelpruivo]

Hi, I have this outlet flashed with HAA and it works fine with this melpha script:

{"c":{"io":[[[4,12,13],2],[[5],6]],"l":4,"b":[[5,5]]},"a":[{"t":2,"0":{"r":[[13],[12,1]]},"1":{"r":[[13,1],[12]]},"b":[[5]]}]}

but now I want to use it as wash machine contact sensor that triggers when the machine ends its job.

Can you help me? Sorry if this isn't the best place to ask, but it's just I make sure the message is not lost.
Thank you!
