Following on from the previous post where I described the RAKO wireless protocol, I’ve created a sniffer that listens for RAKO messages and dumps them to a serial terminal. The sniffer was created simply by connecting an RRFQ1 receiver module to an Arduino as shown in the image above and uploading the sketch which can be downloaded from here.

The more RAKO devices I add to my house, the more I’ve been running into annoying limitations and strange design decisions. Previously I’ve had to create a duplicate command filter for the RAKO DALI bridge due to its assumption that it will be the only controller on the DALI bus. Most recently I was amazed to discover that their three channel LED controller (RLED90-3DCV) doesn’t support dim-up and dim-down commands, instead it reuses these command to go into a colour cycling mode. This makes it useless for controlling my bathroom light and I’d need to use six single channel controllers at £100 each instead.

So, I thought I’d have a go at reverse engineering their protocol. Then I can create my own compatible devices that do exactly what I want and cost a whole lot less.
