hk-volcon

Control your computer's sound volume with HomeKit on Windows, macOS and Linux!

If you experience any problems or instructions are unclear please open a new issue.

Install

• python3 is required, get it if you don't have it
• git clone the project into a directory where you don't mind it staying
• create a new virtual environment to install dependencies. from the project dir do:
  • windows (powershell): python -m venv ./venv and activate with ./venv/Scripts/Activate.ps1
  • linux/mac: virtualenv -p python3 venv and activate with source venv/bin/activate
• install the correct dependencies for your machine's OS with one of:
  • pip install -r requirements/windows.txt
  • pip install -r requirements/macos.txt
  • pip install -r requirements/linux-pulse.txt
• you can try hk-volume out by running python main.py from within the virtual environment (see Known Issues in case of problems)
• in your home app, you will need to pair the new device. the pairing code can be found in stdout-stderr.log, generated in the project directory

Windows Service

• Download nssm
  • extract zip
• copy nssm.exe into project dir
• get the path of the virtual environment's python with (Get-Command python).source
• You need a admin privileged cmd instance
• replace the below paths with the correct locations on your machine and execute them

nssm.exe install hk-volcon "C:\Users\tan\Desktop\hk-volcon\venv\Scripts\python.exe" "C:\Users\tan\Desktop\hk-volcon\main.py"
nssm.exe set hk-volcon AppStdout "C:\Users\tan\Desktop\hk-volcon\stdout_stderr.log"
nssm.exe set hk-volcon AppStderr "C:\Users\tan\Desktop\hk-volcon\stdout_stderr.log"
nssm.exe start hk-volcon

• the pairing code is generated once with the initial start and can be found in the stdout_stderr.log or in server.json

Uninstall

nssm.exe stop hk-volcon
nssm.exe remove hk-volcon confirm
delete project directory

macOS user agent

• replace the paths in org.hk-volcon.plist with the script locations on your machine
• copy plist: cp org.hk-volcon.plist ~/Library/LaunchAgents
• load the agent launchctl load ~/Library/LaunchAgents/org.hk-volcon.plist
• the script should start automatically as agent
• the pairing code is generated once with the initial start and can be found in the stdout_stderr.log or in server.json

linux systemd module

The script relies on ALSA, so it won't work if it is not installed

• replace the absolute paths in hk-volcon.service with the script locations on your machine
• create a directory ~/.config/systemd/user/ if it does not exist
• copy the hk-volcon.service: cp hk-volcon.service ~/.config/systemd/user/
• systemctl --user enable hk-volcon.service
• systemctl --user start hk-volcon.service
• the pairing code is generated once with the initial start and can be found in the stdout_stderr.log or in server.json

Uninstall

systemctl --user stop hk-volcon.service
systemctl --user disable hk-volcon.service
rm ~/.config/systemd/user/hk-volcon.service
# delete project directory

extras

I use a dual-boot setup on a single machine between Windows and Ubuntu. Creating the server.json on one OS and using it on the other as well allows for adding a single device to the Home app while controlling the volume for both OS's.

Program Arguments

• -f Override file name of the config json file. Defaults to server.json.
• -n Override display name of the device. Defaults to hk-volcon (can also be changed later in control center).
• -p Override TCP port to use. Defaults to 56565
• -ip Override IP address of local machine. Use this when the correct IP could not be detected.

Known issues

• The volume slider will show up as a lightbulb in your control center.
• After booting the computer the iOS device may need some time (1-2 minutes) to connect to the homekit server
• If you use hk-volcon on more than one machine at the same time you may need to provide different names for either of the instances
• Sometimes it can be difficult to detect the correct IP address for your machine. A -ip flag allows for manually overriding your ip address.
