Hey everyone, I’m relatively new to the Shelly ecosystem and I’m currently trying to integrate my garage door opener with a Shelly Plus 1. I came across this issue and thought I’d share my experience and seek some advice from the community.
So, my setup involves a Siebau Type 403 garage door motor, which is similar to the Novomatic 403 but outputs 12V DC instead of 24V DC. I connected the Shelly Plus 1 according to the recommended wiring diagram, ensuring the power supply was correctly set to 12V DC. However, I encountered some unexpected behavior.
Initially, the Shelly didn’t establish a Wi-Fi connection and couldn’t be added to my network. When I attempted to connect the relay terminals to the motor’s control contacts, the Shelly powered on once and then stopped working entirely. This was quite puzzling.
Interestingly, when I powered the Shelly using a lab power supply instead of the motor’s 12V DC output, everything worked perfectly—the Shelly connected to Wi-Fi, was added to my network, and the relay functioned as expected. This inconsistency made me wonder if there’s something specific about the motor’s power output that’s causing the issue.
I’ve gone through the troubleshooting steps, including resetting the Shelly and checking the connections multiple times. I’ve also tried using different Shelly units from my order, but the problem persists.
Has anyone else experienced similar issues when integrating Shelly devices with garage door motors? I’m particularly interested in understanding if there are any specific considerations when dealing with 12V DC motors or if there are additional components I might need to ensure stable operation.
Any insights or tips would be greatly appreciated! I’m really excited about the potential of this integration and can’t wait to get it working smoothly.
Thanks in advance for your help!
Best regards,
Frank
