In intercoms that needs activation, there is no way to open without pressing outside. No solution here.
The other issues are normal because nuki have to adjust the different tipology of intercom’s signals to react to the correct signal. They are looking for it . The notifications works in this way too.
Hi,
the Fermax VDS/ADS systems are supported in our 1.3.0 beta firmware version. The way the doorbell get recognized changed in order to only react on the users doorbell signal.
Please send me your Opener ID by PM (goto Settings of your Opener > Connection status and Click on the Opener symbol) so I can add you to the beta group.
Thanks
@Georg_S
Thanks for the beta invite. Tested the whole setup and there are one minor and one major problem.
Minor one: the setup will never complete, the setup where you ring and opener should open never works. Repeated it 3 times and then just told the app, the door was opened, in fact it was not.
Major: If someone ring, you can’t open the door with the app. In fact there is only now ring to open mode available. The normal open option must be available too.
Very welcome is that I don’t get every ring signal from the whole building again. 
Side note: I have a different cabling for ring suppression that also works. Don’t know if I should adjust to yours?
Hi, today I tried to install my opener in fermax 3305 but faced similar issues than commented here: followed the wiring as per app instructions but during configuration it didn’t work.
Can anyone tell me detailed wiring and steps to follow for the success setup?
Cheers
Hi,
for the correct wiring with doorbell suppression please refer to: Known compatibility issues (Fermax VDS with doorbell suppression)
Hola. Yo instale el opener en mi Fermax 3305, y al principio no me funcionaba pero consegui actuallizar el firware del opener y al día siguiente me funcionó.
Ahora mi problema es que cuando activo en “Ring to Open” y llamo desde la calle, al Fermax 3305 le suena el timbre, aunque yo tengo configurado en el menú de nuki que no suene el timbre cuando el Ring to Open está activado. ¿a vosotros os pasa lo mismo?
Ya encontré la solución.
El problema era que tenia que aumentar el tiempo de supresion del timbre que por defecto está en 500 y pasándolo a 2000 el timbre se suprime. Solo suena un pequeño ruido cuando se llama, pero poca cosa.
Aprovecho e indico como lo configure
Hi George, I’ve just installed a new opener (fermax 3390) wired as the app described but ring bell suppression is not working (even tried rising bell suppression timing —hidden option— with no success). Just willing to configure it for Ring to open.
Opener firmware: 1.4.6
In your post yo say:
Fermax VDS Doorbell suppression
In order to use doorbell suppression adjust the connections as follows:
Opener:
black … “-” terminal of the intercom
red… “L” terminal of the intercom
orange… “L” terminal of the intercom
yellow … clamp
green … “+” terminal of the intercom
Intercom:
“-” cable … “-” terminal of the intercom
“L” cable … “L” terminal of the intercom
“+” cable … clamp
With defers from the one instructed by the installation process.
No problem to change it but … Which one should I follow, the one described in the app or this one ?
I’ll appreciate if you could clarify.
Thanks in advance.
Original wiring:
Current wiring:
Ok, I’ve got it working with the configuration suggested by the app. No need to apply George’s suggested configuration (no need to keep on waiting for a reply, either)
Only issue is not having doorbell suppression working (I see many users are complaining about this issue), and support stopped answering regarding this topic. Last suggestion was to play with timeouts (I stopped playing after trying 10 or more values, it’s nonsense to keep on this way without support. Nuki support should keep in mind that we are customers that have paid for a working product, we are not beta testers nor GitHub mates).
At this moment I can’t know if Nuki is going to solve this or even If it’s possible to solve it or not. Nuki has the tools (logs, customer’s patience and cooperation -never, never in my live I have dedicated so many hours with a product to make it work) what it seems is that, for Nuki, customers don’t deserve this kind of clarifications.
The only thing for sure is that, for the moment, I can’t recommend this product to anyone.
Hi all,
Glad to find “Team Fermax” here!
I think I have the FERMAX COLOUR VDS iLOFT MONITOR
I would like to enquire the following.
Is my intercomm compatible to nuki opener? See attach pics for details.
Will I be able to remotely allow lift access to my visitors when they press the intercomm to look for me?
Currently, when visitors press my unit number at ground floor lift lobby to notify me, I need to press my intercomm to allow them to access the lift to reach my unit at level 4. They can only have access to level4.
My main purpose for getting the opener is to allow delivery man up to my unit to deliver my stuff even when I am not at home.
Also I am trying to locate the nuki installation manual to see how to go about with wiring but can’t seem to find it 
Hope to get some advice from Team Fermax 
Hi Oscar, do you have working now??
No, no way to have door bell suppression working. And no assistance from Nuki.
It seems that for old analogic stuff it works but for Fermax VDS is an immature product.
Un unhappy customer here. Last Nuki product I’ll buy.
Lo he solucionado que he apagado completamente el Fermax y he dicho que cada vez que suena la campana he configurado el abridor para que funcione, de esta forma ya esta suprimido y cuando haces el continuo o el auto look no suena nada a menos que no vea lo que también quieres poner un sonido en el abridor, cuando llaman el teléfono sigue funcionando si quiero ver la cámara del fermax lo enciendo, si no por el mismo teléfono se escucha y se abre desde la terminal incluso apagado.
Fermax 3311
Sorry, it looks like Spanish generated with an automated translator. I can’t understand what you have written (and yes, I’m Spanish so I should understand it)
Edito: el 3311 se puede apagar pero no así otros fermax (imposible apagarlos). No es solución. Nuki opener sigue sin funcionar respecto a lo publicitado.
Hi Oscar,
I have problems with fermax 3390 too, wich configuration finally works, the one that you posted here? Many thanks for help
Just deinstalled the opener. Not willing to waste more time with this product. Sorry.
Yes it’s anoying, finally i get it working like other door only limited functionallity… But also checking very interesting Bcn company…
BCN company ? I’m interested. Which one, please ? If it offers an actual customer support I can try their product ( Nuki team, take note ; customer willing a solution searching elsewhere. Congratulations)
I am checking different options to finally decide, not descarting totally nuki for the moment, my email is lpagromayor at gmail dot com
Send me an email 
thanks
