Golmar T-740UNO

Nuki Beta Program Nuki Opener Beta

I have the Golmar t-740UNO

The ideal wiring is this:

For some reason mine has two wires each to the plus and minus:

I wired it according to this diagram

And I set up the app with the Generic Golmar Bus.

And I receive this message:

I’d appreciate any recommendations. I’m willing to try all options.

I can’t walk properly for the next few months so it’s important to get it functional quickly.

This might be important: when wired up according to the diagram (as in the photos) the doorbell does not ring.

We only get an “engaged” tone when pressing the doorbell from outside.

If I disconnect the nuki itself but keep the nuki wiring connected (including the resistor), it behaves as normal.

Tengo el mismo modelo alguien podria guiarme con la conecxion??

I have also the same model, but by looking at the compatibility list it seem that is unsupported.
@OliviaR did you have any success making it work?

@Rafael_Acosta here is the answer: Golmar Plus intercom system support

Finally i decide make one workaround since the Golmar T-740UNO does NOT supported the nuki opener because it is digital and i does not work, no worries I will give you the workaround .

First thing very important is ask someone to call your apartment intercom and press the button without hang it the intercom, if the door opens fallow the next steps…

1 - buy one Shellyplus1
2 - install the APP Shelly and configure the the Shellyplus1 as relay with the time-out of 2 seconds
3 - Open the golmar t-740uno and solder two wires one the push open button, connect the two wires on the Shellyplus1.

Note: for this work you o someone must ring the intercom downstairs, and than you can activated the Shellyplus1 action button.

If you have homeassistant you can setup the Shellyplus1 by find devices and connect using the IP of the devices and make some automatic rules.

I did one automatic rule wirh HA to blink one light when i open remotely, just in case someone is home and don’t waste time standing up the answer the intercom :slight_smile:
