I have 2 RFXMeter devices giving 6 counters in total.
For electricity I use the RFXpwr with current transformer. I have calibrated the RFXWr to get it reading wihthin 1% of the utility meter.
For hot and cold water I installed 2 of my own meters with pulse output.
Here's the links to the meters I used.
I installed the cold meter into the pipework where it enters the property and the hot meter in the hot feed from the combi boiler.
For gas, I have the Elster BK-G4 gas meter installed by the gas company. This meter has a place for the pulse counter to be installed which I obtained from here http://www.mytub.co.uk/product_infor...product=366935
The G4 gas meter does not have an LED or even 1 number that is a different colour, making monitoring with a photo sensor etc almost impossible.
The pulse counter is counting the last digit on the meter which is 1/100 of a cubic meter per pulse.
