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.
This isn’t directly related to nodered, although I do run a nodered automation system which will liaise with the gate.
The shelly 1 dry contact should be fine for the trigger.
You may want to look at the shelly uni for status.
Or may be add a open and closed sensors for reliable tracking position.
Thanks for the reply - looks like the shelly UNI derrives uses its own source voltage to drive its own digital inputs, which implies it is designed for volt free contacts only as inputs. Or am I missing something?
If so, this wouldn't work, as the gate controller is providing a voltage output.
The shelly uni has 2 potential free outputs
The inputs can be wired as in diagram 3a, 3b , 4a, 4b from manual. If i was you i would contact shelly support to ask technical question as to what your gate controller outputs on the status, and if this will work.
The power supply is independent from the input voltages as far as i can tell.
Hmm looks like a bit of uncertainty there, would an opto coupler work wired to the Shelly 1 switched input? I'd wire the status signal to the opto and then it would trigger the Shelly SW input accordingly?
Hi @Sirhc,
I use Shelly Uno's to detect the status of my garage door openers (after I had good feedback on another discussion. Afterwards I found confirmation in the Shelly community that at this moment, Shelly Uni is the only Shelly device that can measure a status (0 or 1) based on an external voltage. I am by far an electronics specialist, but it has been working fine all the time...
