 It would also allow you to combine say the RFGateway sketch using the Nanode hardware with the RF hardware and have the xap-serial message being dumped directly onto the Ethernet. ​ Many options available with these architecture choices. It would also allow you to combine say the RFGateway sketch using the Nanode hardware with the RF hardware and have the xap-serial message being dumped directly onto the Ethernet. ​ Many options available with these architecture choices.

 +<​note>​The RFRX library is part of the HAHCentral sketch so by attaching a RF receiver to this existing hardware you can get this functionality for very little extra cost.  Just the cost of a RF Rx unit, which is about 3-4 quid.</​note>​
  
 The beautiful part of this design is the separation of the signal gatherer from the decoder. ​ We look for a signal that has a lead-in >10ms and repeats more than once.   If this condition is met we emit the pulse stream for a repeating block out to the serial port for the decoder to deal with. The beautiful part of this design is the separation of the signal gatherer from the decoder. ​ We look for a signal that has a lead-in >10ms and repeats more than once.   If this condition is met we emit the pulse stream for a repeating block out to the serial port for the decoder to deal with.
