What happens when an engineer builds a home PI System? Check this out!
Wow Daniel Lopez - awesome setup! Really cool to see such creative uses for PI
That's awesome Dan! Thought about tracking the movement of the vacuum to make sure it has been everywhere?
How did you manage to get the protocol for the electric meter from the utility company?
I think he's scraping the utility's web site rather than talking to the meter directly.
Thanks! I actually am doing it in two ways--you both are correct; I'm both scraping the daily kWh totals from the utility company web site and (in progress) using a USB optical probe, mounted to the faceplate of the meter, to capture its diagnostics output data and extract energy usage readings from that diagnostic data. The latter is a little tricky because I have to work with really old optical formats and some pretty flakey drivers for my probe, so I didn't show much of that in the video.
