Speakercraft MZC-88 is a powerful multi zone audio controller/amplifier capable of switching eight different audio sources on eight zones. Lawrence Watts has posted a very interesting project to control the Speakercraft device using the Flyport. The UART port of Flyport has been connected to an RS232 transceiver to modify the signal level and to properly communicate with the Speakercraft, so bidirectional communication is assured. Then he has developed some webpage to control all the functionalities of the multiroom controller.
Here’s the video:
On openPICUS Forum you’ll find the project. Good job, Larry!
