Hi everyone, I wanted to share my experience with visualizing power consumption using Shelly devices and Grafana. It’s been a fascinating project, and I hope you find it useful or inspiring!
My Goal
I’ve always been curious about understanding how much energy I consume monthly. With the help of Shelly’s smart meters and some open-source tools, I decided to create a system that visualizes my power usage in real-time.
Setting Up the Tools
I started by configuring my Shelly 3EM device to report power consumption every 5 seconds via MQTT. The data is then stored in InfluxDB, which acts as my time-series database. Grafana, a powerful visualization tool, was the perfect choice to create dashboards that make this data understandable.
The Process
- Data Collection: Shelly devices continuously send power readings to my MQTT broker.
- Data Storage: Using openHAB’s persistence service, these readings are stored in InfluxDB.
- Visualization: Grafana’s flexibility allowed me to create a monthly consumption overview. The Grafana query language (GFL) helped me aggregate daily data into monthly totals, providing a clear picture of my energy usage.
Challenges and Solutions
One challenge was filtering out unnecessary logs from my openHAB setup. I added a regex filter to my log4j2.xml file to suppress logging from the power sensor, keeping my logs clean and focused.
Results
Seeing the monthly consumption graph in Grafana was really eye-opening. It’s motivating me to be more mindful of my energy usage. Plus, having this data readily available makes it easier to identify patterns or inefficiencies.
Tips for Others
- Start small. Begin with a single device and gradually expand your setup.
- Take advantage of open-source communities. There are plenty of resources and forums where you can find help or share ideas.
- Don’t hesitate to experiment. Trial and error is a big part of these kinds of projects!
I’d love to hear from anyone who has tried something similar or has questions about setting up their own energy monitoring system. Let’s keep the conversation going!
Cheers,
