Hey everyone! I wanted to share my experience with monitoring and visualizing energy consumption using emoncms.org. It’s been a game-changer for me, and I hope it can help others too!
First, I stumbled upon emoncms.org while searching for a way to track my energy usage more effectively. I was tired of having scattered data and wanted a centralized platform that could log various metrics like battery levels, temperature, and, of course, energy consumption. emoncms.org not only fulfilled these needs but exceeded my expectations!
I decided to integrate it with Vera, and the setup was surprisingly straightforward. I followed the instructions to register for an account, obtain my API key, and upload the EnergyMonitor.lua file. The most challenging part was configuring the inputs and feeds correctly, but the guides on their website were incredibly helpful.
Here’s a quick rundown of what I did:
-
Setup Vera: I registered on emoncms.org, found my API key, and edited the Lua file to include my devices. I chose the second option for energy calculation since I wanted to measure devices not directly controlled by Vera, like my computer using a PingSensor.
-
Upload and Configure: After uploading the Lua file, I added the necessary line to the Startup Lua section. This ensured everything ran smoothly upon reboot.
-
emoncms Inputs and Feeds: I created three feeds—Total W, Total kWh, and Total kWhd—using PHPFIWA and PHPFINA. This setup allowed me to log data at 10-second intervals, providing a detailed overview of my energy usage.
-
Dashboard Setup: The real magic happened when I set up the dashboard. I chose the My Electric app, linked my feeds, and configured the settings to display both current and historical data. It’s incredibly satisfying to see my energy consumption visualized in real-time!
I also explored the My Solar app to estimate potential savings from switching to LED lighting. The dashboards are customizable, and I highly recommend watching their introductory videos to get the most out of the platform.
One thing I struggled with initially was understanding how to create feeds from inputs. Thankfully, the guides on emoncms.org were comprehensive, and after some trial and error, everything fell into place.
If anyone is looking for a free, open-source solution to monitor energy usage, I can’t recommend emoncms.org enough. It’s not just about tracking data—it’s about making informed decisions to optimize your energy consumption.
I’d love to hear how others are using emoncms.org or similar tools. Drop your experiences below—I’m always eager to learn more!
Cheers,
