A RotaryEncoder to MQTT daemon, designed for a raspberry Pi running shairport-sync, but can easily be modified to support more
It supports Volume up, Volume Down by rotating encoder and Mute by pressing encoder.
This is designed to be small and very efficient daemon, completley self sufficent
Utilises the following libraries (included within this repo) :-
External libraries (Only needed if using / compiling with forked-daapd API)
- curl / libcurl4-openssl-dev (Only needed if using forked-daapd API)
Usage is as follows.
-h (this message)
-d (run as daemon)
-ms (MQTT Server:Port)
-mt (MQTT Topic)
-ds (DAAPD Server:Port)
-dp (DAAPD Player ID)
-rc (Rotaryencoder Clock GPIO pin)
-rd (Rotaryencoder Data GPIO pin)
-rs (Rotaryencoder Switch GPIO pin)
MQTT example :- RotaryEncoder -ms 192.168.1.20:1883 -mt "shairport-sync/Living Room/remote" -rc 27 -rd 22 -rc 17
forked-daapd example :- RotaryEncoder -ds 192.168.1.21:80 -dp 11259997263078 -rc 22 -rd 27 -rs 17
clone the git repo and in most cases simply run, no need to compile.
cd ~
git clone https://github.com/sfeakes/RotaryEncoder
cd RotaryEncoder
sudo ./release/RotaryEncoder -ms 192.168.1.20:1883 -mt "shairport-sync/Living Room/remote" -rc 27 -rd 22 -rc 17
If that works, install it as a service
sudo make install
--or--
sudo ./release/install.sh
To compile
edit Makefile and command out `ADD_CURL := 1` if not using forked-daapd / curl
make clean
make
edit /etc/default/rotartencoder
Options should be self explnatory, just pick how you want to set volume, either post to shairport-sync using MQTT or forked-daapd using REST API's. Posting to forked-daapd is a little quicker at the moment, but this only works if you are actually running forked-daapd as you DAAP server.
For shairport-sync you need to enable MQTT and remote with something similar to the below in /etc/shairport-sync.conf
mqtt =
{
enabled = "yes";
hostname = "trident"; // Hostname of the MQTT Broker
port = 1883; // Port on the MQTT Broker to connect to
topic = "shairport-sync/study";
publish_parsed = "yes";
enable_remote = "yes";
}
If using forked-daapd, just get the ID of the player you're setting the volume on, and use that in rotaryencoder's config. Hit the below URL for a list of players on your system.

- added support to use forked-daapd API's
