[Danny] has been working on an RNET to Sonos bridge. These are devices from two different manufacturers used to facility whole-house audio systems. Usually there’s a main controller with a large color screen and then several satellite controllers like the one above which have some of the features but at a lower cost. Normally you’re limited to using hardware from one line of devices in order to get them to talk to each other but [Danny’s] saying ‘no way’ to that restriction.
His latest post has some of the details on how he pulls this off. He used an RS232 serial connection with an Arduino to sniff out the data stream from the RNET base unit. Once he figured out the protocol he used the Arduino to parse all incoming commands, format them for the Sonos controller, and send it over the Ethernet cable to that device. He’s got everything tied together and working. Take a look at the proof in the clip after the break.
