im looking for help and guidance incorporating a button into this code, for use with Arduino, Sonoff and 8266 boards.
i have this running and the relay switching on comand, but i need the button and debounce and i dont know how you do it.
hi !
if I understand well, you want the button to activate the relay ?
eric
sorry for the late reply, yes.
i want the sonoff to work as a wemo switch and have the button work aswell

got this up and running on the sonoff but it needs the button putting in. also some time it turns off after 30mins or so.
Hey Shooter66six, did you get it fix? I have same problem, it restarts after 30-45 minutes. I tried to narrow down the cause by tweaking code but no luck. I asked for help on GITHUB forum but no one cared and no answer from anyone. If you have some updates would like to share? Thanks in advance.
