Hey guys can i hook up a door sensor from an alarm system to trigger system events, or email notifications or anything else? If so do i hook the sensor up to a relay or digital input on my MC3? I know with a security system you can do that type of thing, but i dont have a security system installed. This is not for a customer,, just running out of things to program at my apartment and want to keep doing new things so I can continue to learn the software. BTW trying to do the programming in Simpl.
