I have existing motion sensors on the outside of my buildings and would like to have them as a trigger for my Sonoff devices. The sonoff mini seemed the best choice, but it uses 3.3v for the switching circuits and not the 110v that is being used. Does Sonoff have a product that would accept a 110v signal as a trigger? any outdoor motion sensors that run on 3.3v? I have gone so far as to consider having the existing motion sensors turn on a 110v to 3.3v charger to trigger the Sonoff mini but I wouldn't be completing a circuit with the S1 and S2 ports so I am not sure that the state changes would be interpreted correctly. Any help would be greatly appreciated, I'm looking to keep this simple.
