After years of experimenting with various smart home devices, I finally managed to integrate my Elvox 8879 intercom system with the Nuki Smart Opener! This achievement has completely transformed how I interact with my home’s security system. Here’s my journey and the step-by-step guide that worked for me.**The Challenge:**I wanted to use my existing Elvox 8879 intercom system with the Nuki Smart Opener to enable doorbell detection and automatic unlocking. The goal was to have visitors ring the bell, and upon my confirmation, the door would unlock seamlessly.**The Solution:**After extensive research and trial and error, I discovered that configuring the Elvox 8879 as a generic analogue intercom within the Nuki app was the key. Here’s how I did it:1. Disassembling the Intercom: - Begin by disconnecting the bus wires (pins 1 and 2) from the intercom unit. - Carefully remove the circuit board from the casing without damaging any components.2. Soldering the Connections: - Solder the blue wire to the open button on the circuit board. - Connect the violet wire to the ground point. (Refer to the attached wiring diagram for precise locations.)3. Reassembling and Testing: - Reattach the circuit board and reconnect the bus wires. - Power up the system and test the basic functionalities to ensure everything works as expected.4. Configuring the Nuki App: - Update your Nuki Opener to the latest beta version (1.5.1 or newer). - In the app, configure the Elvox 8879 as a generic analogue intercom. - Test the doorbell detection and automatic unlocking features to confirm successful integration.5. Final Touches: - I also implemented doorbell suppression by detaching the doorbell wire, ensuring that only the Nuki system handles the notifications. - For those experiencing issues with ring detection, reaching out to Nuki support to activate the hidden analogue ring detection setting proved essential.**The Outcome:**This integration has been a game-changer for my smart home setup. The ability to remotely confirm and unlock the door using the Nuki app has added a new layer of convenience and security. Visitors can ring the bell, and I can grant access with just a tap on my phone, all while maintaining the functionality of my existing intercom system.Tips for Others:- Ensure all soldering connections are secure to avoid any intermittent issues.- Double-check the wiring diagram to prevent any misconnections.- Don’t hesitate to reach out to Nuki’s support team for assistance with hidden settings or troubleshooting.I’m thrilled with how this integration turned out and highly recommend it to anyone looking to enhance their home security system without replacing their existing hardware. It’s a fantastic way to blend old and new technologies seamlessly!
