I live in Belgium where we have a 3-phase power supply without a neutral line. This means that every switch in my home is connected to a combination of L1, L2, and L3. I recently purchased a Shelly 1 Mini Gen 3 and wanted to install it behind a switch to control my lights. However, I encountered some challenges in connecting it properly.
After some research, I discovered that the Shelly 1 Mini Gen 3 can work on a 3-phase system without a neutral line, but it requires a specific configuration. I had to connect the device to two live wires (L1 and L2) instead of one live and one neutral. This setup ensures that the Shelly device can function correctly without a neutral line.
I also found that using a voltage adapter or transformer was unnecessary in my case, as the Shelly device can handle the voltage directly. However, I recommend checking the device specifications to ensure compatibility with your local voltage standards.
Overall, the installation process was a bit tricky, but it worked out perfectly. I can now control my lights remotely using the Shelly app, and it has added a whole new level of convenience to my home automation setup. If anyone else is dealing with a similar setup, I hope this helps you avoid some of the trial and error I went through!
Happy automating!
