I wanted to share my experience with integrating the Shelly Pro EM3 energy monitor with OpenHAB. Initially, I faced some challenges with the Shelly binding, as the device would disconnect frequently and the state refresh wasn’t reliable. After some research and troubleshooting, I decided to try an MQTT integration as an alternative solution.
Here’s what I did:
- MQTT Setup: I configured my MQTT broker to handle the Shelly Pro EM3’s data. The device reliably sends updates over MQTT, which proved to be more stable than the HTTP API.
- Rule Configuration: I created a rule in OpenHAB to handle the MQTT messages and update the relevant items. This allowed me to monitor real-time power consumption and set up alerts for specific thresholds.
- Testing and Optimization: I tested the setup extensively to ensure that the data was being captured accurately and in real-time. I also adjusted the MQTT topics to match the device’s output for seamless integration.
The result? A stable and reliable energy monitoring system that provides the real-time data I need. This setup has been running smoothly for several weeks now, and I’m thrilled with the results.
If anyone else is struggling with the Shelly binding, I highly recommend exploring MQTT integration as a robust alternative. It might require a bit more setup, but the payoff in terms of reliability is well worth it. Happy automating!
