I managed to buy the Golmar T540 plus to replace the Platea Uno screen. I followed all the steps. Nuki was playing (unstable eg ring to open not working) and then I realized all the screens in the other apartments were not working. We called a technician and he found out that when the opener is plugged in then the monitors have no power. Any idea what is going on?
I have a Golmar TEKNA-HF GTWIN monitor but they are no longer sold. Do you know if it is still possible to buy them (in the Netherlands)?
If not, do you know if other devices made by Golmar might be compatible (without needing to remove any of the other TEKNA-HF GTWIN monitors in the other apartments)?
What have you figured out about Golmar’s Plus system in regards to the Data and Audio wire?
Any info about the protocol?
I’ve gotten about as far as figuring out it’s 2600 Baud 9-bit UART on the data line that seems to use Multidrop Bus as a base system or something akin to it
While waiting for a better solution, I’ve soldered two wires to the button that opens the door and connected it to a Shelly 1. This way, I can open the door remotely or even by voice.
Hola, pensaba que tenía fotos pero no las encuentro. No es complicado, pero implica desmontar todo el aparato para llegar a la placa, hay que soldar dos cables justo en el botón que acciona la puerta, ahí conectas un Shelly 1 (contacto seco sin voltage).
Intermittent Tonality Issue with Nuki Opener on Golmar Tekna V2 Plus (Bus System) – Could a Resistor Help?
Hi everyone,
I’ve completed the setup of my Nuki Opener with the Golmar Tekna V2 Plus intercom (bus-type system) in my apartment complex, using the Nuki Bridge. The wiring appears correct (I’ve attached pre-Nuki and post-setup wiring photos), but I’m experiencing some instability with the system’s functionality.
Firmware version : 1.10.1
Issue:
-80% of the time, when a user presses the button at the main entrance, everything works fine: the tonality is normal, a call is made to the intercom, and the door opens.
-The other 20% of the time, the tonality is very quick, and while the Nuki Opener seems to receive a signal, the intercom does not seem to enter the correct state to open the door.
Questions:
I’m considering placing an 82 Ohm, 0.5W resistor on the + line to see if it might improve the system’s stability. Has anyone encountered similar issues with tonality or responsiveness, and would adding a resistor help stabilize the signal in this type of bus system?
Could someone guide me on how to use a multimeter to diagnose the issue? Specifically, what voltage values should I be expecting pre- and post-resistor on the + and - lines? Also, what are the acceptable voltage ranges that the Nuki Opener can support?
I’ve attached photos of my wiring setup (pre and post Nuki Opener installation) for reference. Any guidance or suggestions would be greatly appreciated! (cc @Georg_S)
