I just installed 0.9 om a rpi zero and i can send with homeduino but cant recieve. I see the serial light blinking when pushing a remote. And when i cat the output of the serial port to the console i see the recieve events. They dont show up as a message in the messages section and i cant get autodection or a switch to work.
Just update the software on the arduino to the latest version.
@kitsunen sudo cat /dev/ttyUSB0
The /dev/ttyUSB0 could be different on you device. use ls /dev to show all attached devices. it will probably be tty/USB or tty/AMA or something like that
