freitasm: Smart meters for what?
I have a smart meter, and as a tool it's useless. Its reading is sent out to the meter company every couple of days, and then sent out to Powershop every Thursday. Looking at my usage charts they numbers are all averages over seven days.
I wouldn't be able to find out why I have spikes or if anything is wrong here.
Now, the Google Powermeter tool is another story. These CurrentCost devices update in front of me every five seconds, and I have data available on the web up to ten minutes windows.
By just looking at this device I can see when a heater is turned on, and when the home office is going full steam ahead.
You don't get this information from the smart meter.
The Smart meter on the front of our place will tell us the instant current load in KW, but you have to go outside and push the button, - the units are smart enough, it is just they don't tell the customers anything useful .
