Description of the 433.92MHz RFXPower 230Volt.

The RFXPower device measures the real used electricity power in kilowatt-hours. To calculate the used power the line voltage and the current is measured. The total measured value is transmitted at predefined intervals.
The maximum load that can be measured with the standard Current Transformer is 100 Ampere.

Installation:
A Current Transformer must be clamped around 1 wire of the power line and the device must be connected to a wall socket. The RFXPower unit starts then measuring the power usage and transmits the total measured value at predefined intervals.
The interval of the reporting can be changed by the user from 30 seconds, 1 minute, 5, 10, 15, 30, 45 or 60 minutes.
The address of the RFXPower can be set by the user so that theoretically up to 256 units can co-exist.

The preferred receiver for the RFXPower data is the RFXCOM X10 receiver. This receiver can receive the full 48 bits data packets. The maximum power that can be measured before the counter rolls over to zero is 167772.15kWh. The 48 bits data packet enables a parity check on the received data.
The W800 receiver can receive 32 bits and is therefore able to receive the first 32 bits of the data packet. These 32 bits contain the RFXPower unit address and the lower 2 bytes of the measured value.  The maximum power that can be measured before the counter rolls over to zero is then 655.35kWh. A parity check is not possible and the configuration packets can not be received by the W800.
The Homeseer ACRF plug-in version 1.2.0.3 and up supports the RFXPower with the RFXCOM receiver only.
