Successfully Integrating SMA Inverter into OpenHAB

After spending several weeks researching and experimenting, I successfully integrated my SMA Sunny Tripower 15000TL inverter into my OpenHAB setup. This integration allows me to monitor and visualize the solar energy production directly from my OpenHAB interface. Here’s how I did it:1. Setup SBFspot: The key software used to collect data from the SMA converter is SBFspot. I followed the instructions from the GitHub repository to install and configure it on my Debian Jessie VM. The script periodically queries the inverter and uploads the data to a MySQL database.2. Database Configuration: I set up a MySQL database to store the solar data. The SBFspot configuration file was edited to connect to this database, ensuring that all the necessary data points like current power, daily energy, and total energy were being recorded.3. OpenHAB Integration: On my OpenHAB machine, I created a shell script to fetch the data from the MySQL database. This script is executed periodically using a cron job. The data is then mapped to OpenHAB items, which are used to display the information in the OpenHAB interface.4. Visualization: I configured a sitemap in OpenHAB to display the solar data in a user-friendly manner. The interface includes real-time power output, daily and total energy production, and a chart to visualize the energy production over time.5. Automation: I set up a rule in OpenHAB to update the displayed messages whenever the data is refreshed. This ensures that the information shown is always current and accurate.This integration has been a great addition to my smart home setup, providing me with a clear overview of my solar energy production. I’m now able to monitor my energy usage and production from a single interface, which has helped me optimize my energy consumption.If anyone is interested in replicating this setup, I’d be happy to share more details or provide assistance. It’s a rewarding project that combines solar energy monitoring with smart home automation, and I’m excited to see how others might expand on this idea.
