Im on a real steep learning curve with all this monitoring, but I have learned a lot! I have solar PV, an ASHP, Tesla Powerwall2 and run on Octopus Go, charging the battery overnight and topping up with solar during the day.
So far I have managed to get the basic system (EmonPi, EmonTX and multiple current clamps) installed and operating, navigating through inputs and feeds and building a dashboard.
The with a lot of searching (and help) in the forum and on google managed to interface to my Powerwall and pull off lots of data and create new feeds (had to teach myself the basics of Python and JSON for that to understand what what going on!). Then I got advanced and linked my Octopus smart meter in and now have 3 years of half hourly data available (I just love data!!) and getting updates every day. But I think I have reached the limit of my knowledge now!
I would like to be able to display cumulative (on a daily basis) power consumption for the offpeak and peak time periods. I have the historical data available and can get the real time (well every 30 secs or so) from the powerwall feed. Clearly it is possible (the time of use app) but i would like to display this in my own dashboard (and I cannot find the code for the time of use app (assuming it is written in python) which would help me replicate the analysis.
Can anyone point me in the right direction to get started on this?
Many, many, many thanks in advance!!
