Nuki Opener with Bticino 334262 or 334202

[MathildeV]

Hello
I’m not completely sure of the exact version of my Bticino Intercom, but according to google it looks like the 334262 or 334202.

Anyway I was not able to find a scheme on the Nuki app that could work.
I have several appartements with the same Intercom so I would really like to make it works.

Can anyone help me to find the right wireing please?

Thanks,

I have a very similar bticino intercom system.

Unfortunately, the Nuki Opener does not fully decode the bticino protocol, it only captures/replays packets, which might work in some cases, but did not work reliably at all in my case.

I have written quite a lot about the underlying issue and the fix that I ended up using:

• Nuki Opener with an SCS bus intercom (bTicino 344212) (2020) - Michael Stapelberg
• Fixing the Nuki Opener smart intercom IOT device (on the BTicino SCS bus intercom system) (2020) - Michael Stapelberg
• Make your intercom smarter with an MQTT backpack (2021) - Michael Stapelberg

Hope this helps, and I also hope that some day Nuki developers will actually implement proper bticino support…

Maybe it will get implemented if enough Btcino users vote:

Nuki Opener - Support Btcino Intercoms (SCS Bus)

Product name Nuki Opener Summary Support all the Btcino BUS Intercoms that run on SCS Bus. Somehow you can configure it, but Ring-to-open, Ring Sound suppression and Notifications never work. The user stapelberg put much effort into analyzing the problem and finding a solution (decode signal to work reliable): Unfortunately, the Nuki Opener does not fully decode the bticino protocol, it only captures/replays packets, which might work in some cases, but did not work reliably at all in my cas…

i have successfully connected Nuki Opener with Btcino 344262. I attached the scheme. All functions are working as expected
