I recently bought NUKI Opener for my apartment and I have a Fermax Reference: 2452 (CITYMAX VDS EXTRA) which doesn’t appear with this exact name in the compatible devices. Although it’s a VDS 3-wire terminal with -, +, L sockets.
I have been trying different configurations: from Fermax VDS specific ones to Generic config for Fermax (ADS/VDS) or Generic Bus.
I managed to get to the door and it recognizes the ring tone, but when I press the button it doesn’t open the door. Also, ring to open doesn’t work. It seems like Nuki Opener cannot send the “open” signal to my terminal or something like that.
I have no idea on what else to try, so I guess if I cannot make it work I will use my right to send it back and get my money back.
If any of you knows what could be happening, it will be really helpful. Thank you very much in advance
In my opinion, this is false advertising: the opener is not compatible with Fermax VDS devices, which make up a significant portion of the range. Throughout the forum, I have never seen a user who got it working correctly and shared their solution.
I have written to the developers and posted several messages, but I have never received a response. Nuki devices are not compatible with all the devices they claim to be, and this is deceitful and commercial fraud.
For users who, like me, have encountered installation issues with the Opener on FERmax products using a VDS BUS with 3 connectors (+), (-), (L), I finally found a solution that was suggested to make them work. The wiring I used is black on the (-) connector and red and orange on the (L) connector. Follow the steps, repeat them several times if necessary, but usually, after a while, the installation works.
Currently, the Ring to Open and Continuous Mode functions work, but not the smartphone opening. I will provide you with feedback on any future updates. Best of luck to you, as personally, I struggled for hours and hours doing thousands of tests, connections, browsing forums, etc.
I am about to give it a last try before returning my opener. So, you just connected these three wires and nothing else? And did you set up anything else in the App to use the Ring to Open?
Sorry for the delayed response. At best, this will help other Opener users.
I only connected its connectors, and it was working, but…
After a breakdown, I just installed a new device, and now nothing is working. I encountered numerous issues during the installation: update problems, Bluetooth connection issues, connection issues with the bridge… I managed to resolve all these problems, but I still have an issue with the intercom’s opening signal. The device does not detect the opening signal.
I will write to the developers to try to find a solution, but I fear it will take several more months before the system works properly for my Fermax 3390 on BUS VDS.
