I came upon this little sensor - Grove - Gesture Sensor (PAJ7620U2) | The Pi Hut - and thought it would possibly make a cool way of controlling Roon
In combination with this extension - Roon Extension: macro.on
Basically, install the sensor on a Raspberry Pi, install the required libraries, set up the above extension, and you can control Roon by moving your hand over the sensor. There are a total of 9 possible gestures, so you could do p preprogrammed things using the macros provided by the extension above.
I use mine to play, stop, raise and lower the volume and play 2 radio stations.
I’ve got the raspberry pi in a kitchen cabinet with the sensor just poking out of a hole on the side.
Here are some links that may be useful to set it up -
This is different project using the sensor - the installation section and the library files will be useful -
Finally, here’s my python script that actually links it with the macro.on extension above
Happpy to help with specifics
