Monitoring electricity usage
managed to get this done too, put a monitor in my fuse box (ADM1.5TE) , cost < £30 GBP, and a small serial board (WTDIN-M Digital input module) to count the pulses and read them via serial. I also got some adm1d meters, haven't put them in yet, but hope to break out socket rings and lights from the overall total. Hats off the the kinds folks at jw instruments who sold and shipped them to me.
