Current Cost Support Forum

I asked that at http://currentcost.posterous.com/optism ... developers

Alas no response

Also with the display dividing the pulse count by typically 1000 one would sure have to use some water or gas to make the envir read a few watts!

I imagine the only real way to make use of the data would be using the impulse count with your own custom app (unless the new my.currentcost.com out next week supports it).

I have to do such a thing with my gas meter using another product which gives me these results...

The "water meter" is in my solar HW system and measures in litres so in sunny weather the meter clocks a reasonable number of pulses. Conversion from "watts" to litres would be done in the database. I'm afraid the the electronics would be a step too far for me. My "hobby" electronics skills are fairly basic. So as soon as someone cracks this, I am sure my soldering iron could follow the instructions.

If implemented correctly the power usage will be the same or less. The system should be able to enter a low power state until a signal is received from the passive sensor unit. The power draw from microcontrollers is in the micro to nano amp range. For example and AVR XMEGA microcontroller has a power consumption of 100nA with 5µS wake-up time. A 1Ah batter could power it for 10 million hours (i.e. a very long long time).
