I am thrilled to announce that the famous Open Energy Monitor can used as an input in the build of my DIY Energy Storage System or ESS instead of the original (also famous) Wattson Energy Monitor
From the very beginning back in 2011, I purchased and installed Wattson at home and loved it: I could finally see in real time how much power my appliances use and modify my behaviour to reduce energy consumption at home
Later on I got Solar Panels installed on our building roof and used another feature of Wattson which is Solar Surplus detection: When Usage < Solar, Wattson simply lights up Green to indicate there is free Solar Power to used (and the Net Usage is Negative)
Wattson Solar Surplus (and other color codes):
Based on these simple lights (Blue, Purple, Red and Green) I built my Energy Storage System back in 2013, had it running for over 2.5 years now with Solar (july 2013), and saved over 650 EUR on my Electricity bills
Last friday, inquiring on the Open Energy Monitor and their interesting open source work over the last years, I realized that their emonGLCD, the equivalent to Wattson Display, is actually using the same Color Codes, in a simplified version:
- Green: Solar Generation > Usage
- Red: Usage > Solar Generation
OpenEnergyMonitor emonGLCD Solar Surplus :
Simply wiring the pins of one of the bi-color LED pins to the input terminal block of my DIY ESS, it will get the color codes and perform exactly like if it was a Wattson display :)
OpenEnergyMonior solution is open source, meaning it will be improved over time (and you can participate too)
It is also now possible to get a ready to use emonPi, meaning there is nothing to solder and build, just clip your CT Sensors (or clamps) on usage and generation wires, plug them in the device, power it up, and you're good to go !
But there's one more thing ...
Connected to you home internet router, OpenEnergyMonitor will post data to Emoncms.org, allowing you to see great graphs of your usage, generation, temperature, etc ... All this for free, so I think it's just perfect :)
