With all those energy pulses flying through the air, we don’t even need a central setup to display this information on a little self-contained Graphics Board display – like so:
The “homeGraph.ino” sketch which drives it has just been added to GitHub:
There’s room for a little graph, but it’ll have to wait until the home usage counter has been rewired to measure the proper value (the value shown above is in fact the surplus).
Nice :) The picture also suggests that you have solved the wireless power problem ;)
Just what I was planning to make. I even have the enclosure ready. Different payload for me, but your example is a great start… Thanks.
Hi, What kind of enclosure are you using ?! Rudi
Good job, I even made my own PCB that better fits the GLCD and you could even log data to the SD card for later use.

Yes, that’s a very nice setup indeed – doesn’t stick out as far as a JN.
I’ve also found a lithium battery from a phone that’s similar size to the GLCD and it powers the whole thing for about a week, I’m sure I can extend that a bit more though.
