 Energenie also offer a specific add-on hat, for use with a Raspberry Pi, but a lot of people have found that the generic Hope RFM69 radio module (which is an SPI bus-interfaced radio module) works just as well.

+=== Duplication of remote control functionality ===
 One of the problems with the Energenie RF system, is that out of the box, the handsets are pre-programmed with device codes which you pair with the sockets. It's not possible to read what those codes are (which would be necessary, in order for the power sockets to respond to another radio device), and there's nothing on the handset or PCB to say what those codes are.

+...these are strictly broadcast-only devices which send a burst of power metrics over the same RF signal as the power sockets, approximately every 60 seconds. The PyEnergenie project also had support for these, so I was able to pull this data in using the same RF module used for controlling the sockets, displaying it on the touchscreen at the press of a button:

+This screen let me monitor the power use of all of the sockets in the room in (almost) real time. There is a lag for the power monitor sockets to re-broadcast their data (it's every 60 seconds or thereabouts), but it's good enough to see the loading on the 4 wall sockets in the room, along with the various power strips that run from them.
