Re: 3: my automatic gate is one of those villa/garden two sides heavy metal gates with hydraulic arms, and works like this: push N.O. button once (close contact for a few ms, 1 sec is also ok), sides of the gate open and continue open after you release the button; after 1-2 minutes they close on their own. if you press button again while they are closing, they stop and reopen again.
So I just want to make sure, can OG mimic just the open action for a few ms/1 sec and that’s it?
For the monitor, as the ultrasound would not work and OG is not waterproof, I would put it in an sealed box, and connect to it an external magnetic sensor that closes contact when the two sides of the gate are closed.Is this also possible?
