Hi Thomas, Thanks for the link. I can't tell from their description what type of meter it will sense. Mine has a spinning metal disk with a black stripe on it. I think it would be quite challenging to sense reliably. It would certainly be worth 39 Euro for something that did it well. = Cheerful regards, Bob On Tue, 11 Mar 2008 08:23:46 +0100, "Thomas Lehmann" said: > Hello Bob, > = > please look here: > = > http://www.elv.de/output/controller.aspx?cid=3D74&detail=3D10&detail2=3D1= 5910 > = > which is a complete system for energy-measurement at home with a > rf-transmitter and a receiver.
