As said in a couple messages, I ordered an assembly to get my real time consumption from the electricity meter.
I moved the spare laptop, plugged a wifi USB key, recompiled the kernel to get the wifi driver, plugged the assembly, recompiled the kernel to get the serial USB driver, wrote a couple rrdtool scripts, waited a couple days and obtained this
More information this week-end.
Tomorrow evening I should plug the assembly on the production meter and measure the PV production Friday as it should be a sunny day
If it works then I'll order a second assembly to have both meters recorded in real time
As the protocol is full of French words or keywords based upon French words, this shouldn't work on US meters...
Denis.
