I am here trying to use my brand new Nuki Opener with a Fermax 2451 VDS (kinda old model, much common in Spain).
I’ve seen several discussion about setting up the cabling and stuff, but could not make my head around such rigmarole of trials, errors, firmware updates, cable colors, and differing advice.
I guess a lot of Nuki owners are giving up and just returning their Openers because I’ve never seen such an immature state in a (supposedly marketable) product.
So, how come one cannot make it work without at least a couple hours worth of stress and technical issues?
This is a kinda old, basic VDS “compatible” interphone which is the digital bus 3-wire variety. To start with, the colors of these 3 wires coming to the interphone from the outside world are just anyone’s guess.
I’ve never seen a clear, definite explanation about what the A-,A+, Bus+, Bus-, -, + on their own, L symbol etc. are supposed to refer to, or be wired to…
Can someone explain in plain terms? Believe me, I’ve got kind o knowledge about gadgets all kind, even program my own uCs/ Arduinos to try to integrate home automation solutions to my taste. But THIS… oh well THIS is not up to anything resembling a company’s good practice in regard to their products’ installation procedures NOR support thereof!!!
There was some “Michel” out there sorting out his own problems. Apparently he came out with a solution but was not clear enough pointing out how he did succeed finally, I guess it was just a drop of “firmware update” sheer luck ???
Please! I am desperate and thinking of returning my Nuki!
