Hi everyone, I wanted to share my experience integrating my LaMetric display with my Solar Photovoltaic Power Plant. It’s been a fantastic way to monitor my energy production and consumption in real-time. While I know there’s an addon for this in openHAB, I decided to create a custom solution using Python scripting. Here’s how I did it!
First, I set up my LaMetric to display various data points such as exported energy, current PV production power, and even the Nord Pool energy spot price. I also integrated it with my Sonos system to get notifications on what’s playing. It’s been incredibly useful to have all this information consolidated on one display.
I wrote a Python script using the Helper Libraries for openHAB Scripted Automation. The script pulls data from my energy monitoring system and sends it to the LaMetric display. While the script itself won’t work out of the box for everyone, I’d be happy to share it for anyone interested in adapting it to their setup.
Here’s a quick overview of what the script does:
- Fetches and formats energy production and consumption data
- Retrieves current and hourly Nord Pool energy prices
- Updates the LaMetric display with real-time information
I’ve included some of the key functions in the script, like formatPower and formatSpotPrice, which handle the data formatting. The script runs as a rule in openHAB, triggered by changes in the energy price or on system startup.
This project has been a great learning experience, and I’m excited to see how others might use or adapt this setup. If you have any questions or suggestions, feel free to reach out!
Cheers!
