Hey everyone, I wanted to share a recent project I undertook that combined traditional wiring with modern smart home technology. I recently renovated my attic, and as part of the project, I wanted to add a third switch to control the same light circuit from three different locations. This was a bit of a puzzle at first, but I managed to find a solution using Shelly devices, and I thought I’d walk through the process in case anyone else is tackling a similar challenge.
First, a bit of background: I had a classic two-way switch setup, which worked perfectly. However, the new bedroom I was setting up on the attic required a third switch near the door for the same light circuit. The challenge was that running new cables wasn’t feasible, so I needed a wireless solution that could integrate seamlessly with my existing setup.
I decided to use Shelly 1 devices for this project. The Shelly 1 is a simple yet powerful device that can turn any regular switch into a smart switch. The idea was to replace the existing switches with Shelly 1 units and configure them as a three-way switch system. This way, I could maintain the traditional switch functionality while adding the convenience of smart home integration.
The process involved a few key steps:
-
Replacing the Switches: I started by replacing the two existing switches with Shelly 1 devices. This was straightforward as the Shelly 1 is designed to fit into standard switch enclosures and connects directly to the existing wiring.
-
Adding the Third Switch: For the third switch near the bedroom door, I installed another Shelly 1. The key here was ensuring that all three switches were properly configured to work together as a single circuit.
-
Configuring the Shelly Devices: Using the Shelly app, I set up each device as part of the same group. This allowed me to control the light from any of the three switches, maintaining the traditional toggle functionality while adding smart features like scheduling and remote control.
-
Testing the Setup: After configuring everything, I tested the system thoroughly to ensure that all switches worked in unison. It was a relief to see that the light could be turned on and off seamlessly from any of the three locations.
This project was a great learning experience, and it highlighted the versatility of Shelly devices in integrating with both traditional and modern wiring systems. I’m now confident that I can tackle similar projects in the future, knowing that Shelly offers a reliable and flexible solution for expanding switch systems without the need for rewiring.
If anyone has questions about this project or similar setups, feel free to reach out! I’d be happy to share more details or troubleshoot any issues you might encounter.
Cheers,
Sönke
