Hi all, after doing some continuity and voltage measuring I’ve managed to find a way to have the NUKI opener working with digital Fermax 9445 and possibly with any digital intercom.
Please find the procedure I use to open the door remotely:
Push the button from the main intercom (outside the house) referent to your door (FERMAX will turn ON and will have available around 3V at the terminals where I connected the wires. Just used the blue and purple wires);
Push the button at Nuki app to open the door (This will close the circuit at the terminals simulating the same as you push manually the “key button” on the intercom inside the house);
I’ve created a video ( https://youtu.be/KLom-Lsv6L0 ) with all photos of what I’ve done and hope it is clear.
I’m happy to clarify any step.
I have the opener connected to the bridge and didn’t make any changes to the settings.
Those connections I’ve done were just to open the door remotely when the FERMAX is active (someone rings the doorbell), when someone rings the doorbell I don’t have any notification on my opener.
It might be possible with the other wires on the Opener, to do an additional connection to get the notification when someone rings the door.
This connection when pressing “Ring to Open” on your app, will close the contact on the microswitch on the FERMAX, but if the FERMAX is not active, will do nothing.
Hi g0day, thank you for your message, and apologies fo the delay in my reply, didn’t see tye message in my email.
Yes, I have this in a house abroad and I’m not going there often but hopefully, next time will go there I will try to do some experiments.
Trie it, as these wires are from a dry contact so no voltage on those wires, and let me know if is working.
I had a bug last time replacing the batteries and had to do the configuration again and forgot to add o this post configuration that I used from the Nuki list which was the Fermax 94120b despite I’m having a Fermax 9445.
Hi Rose, thank you for your message.
Yes it has…yes it might be possible, the next step I’m trying to do is to turn the Intercom active via the opener app to be able to open the door remotely without the need to ring the bell.
