RFXCOM receiver for Electrisave / cent-a-meter

[b_weijenberg]

The RFXCOM USB X10/Oregon/KlikOn-KlikOff/Domia Light receiver is able
to receive also the Electrisave (cent-a-meter) RF data. http://www.rfxcom.com

Some explination on the Electrisave versus the RFXPower:
The Electrisave measures the current of up to 3 phases. Using the
RFXCOM receiver the received data can be logged to the PC and the
data can be used to create graphs of the power usage.
In the standard Electrisave configuration the measured current will
transmitted to a display unit where the current (ampere) value is
multiplied by a fixed voltage parameter. It displays then the power
usage for that single moment. But the displayed power value is not
very accurate because the voltage is a fixed parameter in the display
unit while the real line voltage fluctuates a lot. So it is not a
real power usage meter but in fact an Ampere meter.

The RFXPower measures the real power of 1 phase by multiplying the
measured current times the measured voltage. The internal kWh counter
in the RFXPower unit is increment for each use of 10Watt and is
therefore comparable with the utility meter.
Connoleg has written software to show the power usage in Homeseer:

I suspected and hoped you would include this Bert - thanks - I now cannot resist any more buying one of your receivers! Going there now to order! Of course I may then end up getting a RFXPower, but this will do for now.

Bert,

While desperately searching why my HS system eats up 100% CPU i noticed this one in RFXreciever.

14-11-2010 18:41:46= 781A2905550A4041F15747F187070000 bits=120
14-11-2010 18:41:46= 6CEA28FEF00000000000000060AF07 ELEC1[65024] cent-a-meter addr:FE counter:8 CT1:24 Ampere CT2:0 Ampere CT3:0 Ampere Checksum Error bits=108

I got a reading of cent-a-meter while there is none anywhere near in or outside my house.
This is probaly a faulty reading, right?

This is indeed a feulty received packet. Some bytes indicate a ELEC packet but the checksum indecates that the packet is not OK and will be skipped.
