-The [RFXtrx433e](http://www.rfxcom.com/RFXtrx433E-USB-43392MHz-Transceiver/en) is required for RFY support, however it does not support receive for the RFY protocol - as such devices cannot be automatically added. Instead, configure the device in the [rfxmngr](http://www.rfxcom.com/downloads.htm) tool. Make a note of the assigned ID and Unit Code and then add a device to the configuration with the following id `071a0000[id][unit_code]`. Eg, if the id was `0a` `00` `01`, and the unit code was `01` then the fully qualified id would be `071a00000a000101`.
