Power to the Pi from the Panel I didn't try. I went through the effort of installing a standard power port within the box below the panel and have my Pi plugged in via USB (connected via romex to a floating socket - cheap cheap at Lowes) - probably your best bet. I'm using a Pi1 b+ and had an easy ethernet run but I'm sure it would all be fine via wifi as well. I was more interested in time based stats and graphing out temps and pump wattage and such and Grafana provided an easy interface for tossing in html controls as well. I have it all converted from Ruby to GoLang and compiled on the Pi now as well... but the UI is the same as my last pics. I also like the idea of single-boxing this with a Pi3 and housing influxdb and grafana locally instead of using a separate server as I am now. Now that I have it all in go I'm working on reading/writing pump schedules. My end goal here is being able to remove the easy-touch altogether and have a stand-alone home-grown controller... so far, as you can see from my pics, its going good... maybe I'll have time to work on it more in a couple weeks, but I haven't been able to for a while here with busy life
