I’ve been on a journey to integrate my Shelly Pro EM3 with OpenHAB for solar power monitoring, and it’s been quite the adventure! Let me share my experience and some tips I’ve picked up along the way.
The Challenge:
I wanted to measure the solar power export from my balcony setup and automate my smart plugs to sync with solar production. I installed the Shelly binding in OpenHAB 4, but it wasn’t reliable. The device would disconnect, and the states wouldn’t refresh consistently. I tested with the latest firmware on both the Shelly and OpenHAB, but the issue persisted. It seemed like either the Shelly API or the binding wasn’t optimized for the EM3 Pro yet.
The Solution:
After some research, I decided to integrate the Shelly Pro EM3 over MQTT instead. I set up my own MQTT broker and configured the Shelly to publish its data there. This approach has been much more reliable! I can now monitor active power in real-time, with updates every 5 seconds, which is perfect for my use case.
Tips for Others:
- If you’re experiencing issues with the Shelly binding, consider switching to MQTT. It’s straightforward and offers more control.
- Ensure your MQTT broker is properly configured and secure.
- Explore the Shelly’s advanced power analysis features—they’re a game-changer for detailed monitoring.
The Outcome:
This setup has transformed how I manage my solar energy. I can now optimize my energy consumption in real-time, reducing waste and maximizing efficiency. It’s been a rewarding project, and I’m excited to see how it evolves!
If anyone has questions or wants to share their own integration tips, I’d love to hear from you! Happy tinkering!
