I have a centys d5 evo gate opener and I’m trying to remotely open/close and also get open/close status back to my home automation system.
Manual location here
In the manual it appears as if the trigger input and status output on the controllers can be used to do this. See attached screenshots.
The status output looks like it pulses with a 4.8v output depending on gate status. I can write some code to interpret the pulses no problem.
I’m trying to use a Shelly 1 switch for this since I know they’re reliable. Do I use the dry contact on the Shelly for the trigger input to the controller?
And for the status, would I need to use a 5v interposing relay between the Shelly and controller? It looks like the SW input on the Shelly needs min 12v to detect but the controller only outputs 4.8v so not sure if it will detect.
Yes a Dry contact mode is used with relays to allow pulse setups, Wet is used for power sockets.
You would not need scratch code. The shelly is just acting as a trigger for the garage door/gate opener to start, stop and reverse the motor to open and close it via the trigger line.
and with gates folks set it to sleep after 0.5s to act as a push button action event.
You need -12v to trigger shelly SW, so either use optocoupler or transistor circuit or simply buy separate shelly blu door&window, it’s pairing with shelly plus
Thanks for the replies. I’ll try the optocoupler. Just looking at the 4N25 datasheet:
The collector emitter breakdown voltage is 70v. Does this mean the optocoupler can handle up to 70v across its output ? And I assume 5v is no issue on its input since it’s just an LED
