Unofficial module for managing Genelec SAM monitors through the GLM network adapter.
genlc is a Python module allowing (automatic or manual) control of Genelec loudspeakers (monitors/subwoofers) in the Smart Active Monitor range, i.e. those with GLM network connections. genlc currently implements the very basics, i.e. a tiny subset of GLM:
- discovery of monitors on the network
- wakeup and shutdown
- polling of some parameters of monitors
- volume setting
- mute and unmute
- LED on/off/color/pulsing
A CLI application with the same name is included for easy control from the command line.
The GLM protocol used by Genelec is a proprietary binary protocol, which is being reverse engineered to implement genlc. Therefore there may be surprises, and YMMV. The code has been tested so far with 2x Genelec 8330 and a 7350 subwoofer.
My main use case is/was to better integrate my Genelec monitors into my Home Assistant setup for music listening and home theater applications, but with a generic Python module a lot more could be possible.
Show information about all SAM devices on the network:
$ genlc discover
Set volume to -18 dB:
$ genlc set-volume --volume=-18dB
Mute a single monitor with address 2
$ genlc mute -m 2
Show certain parameters of all monitors continuously, every 3s:
$ genlc poll --continuous --interval 3
Combine multiple commands:
$ genlc discover wakeup set-volume --volume=75% poll --count=10
...or even repeat the same ones:
$ genlc bypass -m 2,3 --led-color red --led-pulsing bypass -m 4,5 --led-color yellow --led-solid
More usage information:
$ genlc --help
For now this is very experimental code, best pip3 install from the repository URL if you have pip 19.0 or newer. I intend to publish it to PyPi once things are a bit more stable.
$ python3 -m pip install git+https://github.com/markbergsma/genlc#egg=genlc
genlc depends on the libusb/libhid libraries to access the GLM USB adapter, and those should be installed separately. Best use the libusb0 backend of libusb, although hidraw0 could also work (untested). To install on e.g. a Debian-derived system, this should work:
# apt-get install libhidapi-libusb0
