Are there any commercial electricity power meters like the "cent-a-meter" or efergy's power meter that are network enabled. Ie, can connect to the local LAN network via wifi or something. Essentially, I wish to get a whole bunch of these devices to monitor all the electrical devices in the house. With them wifi attached and possible with SNMP, use something like cacti to poll and log the instantaneous kW and kWh. I can then get a combined total which would represent the house hold usage rate. The reason I want to do this is that the electricity bill is about 2 times more than I think it should be. Even if I can't get it for all devices in the house, I would at least like to be able to attach to the incoming power line to the house. The problem I have is that the diameter of the cable is too big for me to clip the power meter onto and it appears that the cable in the meter box already has the neutral and active combined. Any suggestions for that?
