Nuki Opener - Digital Urmet Installation

Good afternoon everybody!

Could anyone help me with an Opener issue with an intercom by Urmet? It is a 1133/1 model, which should be analogue, but it’s actually digital as I only have 2 wires in the housing.

The Support team has kindly provided me a guide for Unknown Systems (Bus intercoms).
I am attaching the picture of my intercom as reference.

Should I connect to black cable to the BUS- and red and orange calbes to BUS+?
Has anyone already overcome a similar issue?

Thanks for your precious support!

I assume your white and blue cables are not connected to anything (it’s not visible on the picture).
Some Urmet systems have been retrofitted with newer internals. Your’s seems to be one of those.

Urmet bus has not been confirmed to work with the Opener, but you can try if it works:
Connect RED from the Opener to RED on the intercom and BLACK to BLACK. When you configure the Opener select “Generic” as brand and “Bus (Generic)” as model.

Thanks Jurgen.

At the end of the game, the opener works! It worked with the Enhanced scheme of the guide.

I have an intercom which requires the pre-activation, so I thought that before starting the “learning mode” of the configuration, someone else had to ring the bell downstairs. I asked my father to do so and we stayed in contact with the mobile. (Maybe the pre-activation should be mentioned since the very start of the configuration).

I would like to activate the “Ring to Open” option, but it seems it does not work. Shall I activate the Continuous Mode? To be honest - my fault - it is not very clear to me the difference between both the options.
Please help. :slight_smile:

In Italy NUKI it is not distributed frequently and should. I bought the entire set on your mobile as, for istance, the Opener is not available in the distribution centers.

Btw thumbs up for you at Nuki, guys. Great, AMAZING, home solution!

Good that it worked.

Ring To Open in the App can be activated by swiping up the bottom sheet:

Can you share a photo or a scheme of your setup? I have an Urmet intercom too and probably your scheme can be a starting point :slightly_smiling_face:

I am trying to set up Urmet 1131, seems digital to me, only 2 wires (+ and -) connected.

We did use “generic” “bus” instructions for enhance setup:

Photo of the Urmet 1131 inside looks like in attachment (photo from the Internet, but it looks identical).

We did get some progress, but we cannot get Nuki to actually open the doors. Even after we tried this pre-activation.

Can someone share exact steps?

Update: I have completely given up on NUKI with this intercom. My NUKI device lies somewhere in the dark closet …

Hi there, I have the same configuration an urmet 1133/1 that is actually with a digital bus and not analog.

Here is the wiring I use :

Configuration was a bit tricky because it is a pre-activation mode; meaning you need to ring the interphone first before you could open.

So when you configure it use “Generic” as brand and “Bus (Generic)” as model.
So when you start the learning process make sure someone press the interphone button before you push the opening button.
Then go down to your interphone and follow the process.
The tricky thing was that you need to had a waiting period of 3 seconds in my case, otherwise it doesn’t work because the answer to the ring starts before the end of the request.
So in my case, in the second stage where you try to open it in preactivation mode, I told the system it has open even if it was not the case. Then I edit the configuration and a a 3s waiting period and then it was working.
It’s pretty cool especially with smart action, you don’t need to pull your key out anymore.
However, it seems that it is not possible to mute the interphone by the configuration with this model.
Enjoy :slight_smile:

Hello everyone, I have this intercom Urmet 1750/6 and really need to make it work as the apartment is planned for Airbnb, are there any news, or maybe there is a possibility to change the internal unit to make it work?

Have a look to Urmet 1750/1 - #19 by Dennis_Vermeulen : So far it seems that these models, including yours are not supported on nuki opener.
Sorry for you,
Best regards
PS one of the post suggests switchbot as an alternative, it might helps except you couldn’t share it with Airbnb directly, at least it’s a possibility.
PPS contact the nuki support directly they were quite helpfull in my case.
