Hey powerwall builders,
first of all, I would like to wish everyone a happy new year and apologize for my rusty English.
Project I plan on doing is measuring household power usage 24-7 with esp8266, to determine how much power I need to install in solar panels and how big storage in batteries would be themost cost efficient for me. I also love analyzing a lot of data, so that's another reason. Just looking at power bill isn'tenough for me, because I would like to see my power consumption during different time periodswithin a day and be able to determine how much power every device consumes. My overall goal in the future is to be able to turn off devices like internet router or water heater automatically when nobody is at home to save some money on my bill.
To be able to store a large amount of data (from multiple households) I decided to use a Linuxbased server and do all the data processing on theserver side. This will also allow easy data (graphs etc.) accessfrom any device (PC, phone etc.)
Let's talk electrics. I want to measurethe current flowing through all the phase lines just behind the electricity provider meter. I found really neat split core transformers that would be perfect for this application. (SCT-013-XXX)
I may even measure the voltage level to see the deviations in it over time. With thatdetermine if I need to include the voltage in my calculations. After that it's simple circuitry, just convert the analog data to digital form and send them to the server withesp. I think the picture describes the process nicely.
I wanted to ask u guys if anyone is already somehow doing this, so I don't reinvent the wheel. If not, I would like to ask if anybody would be interested in using this device. I plan on making a schematic and even a board design available to make it easy to construct. To keep the cost low I would make the server accessiblefor all of you interested. I am gonnamakea client PC based appto displaythedata. (maybe even an app for android)
Thanks for reading this, looking forwardto any suggestions/feedback.
