Replace the final if block with this code to toggle the lighthouse state, when no argument is specified.
That is, this change will turn the lighthouse off when it's already on, and on when it's already off.

        if len(sys.argv) > 1 and sys.argv[1] == 'on':
            lh.writeCharacteristic(0x12, b'\x01')
        elif len(sys.argv) > 1 and sys.argv[1] == 'off':
            lh.writeCharacteristic(0x12, b'\x00')
        else:
            # toggle
            current = lh.readCharacteristic(0x12)
            if(current) == b'\x00':
                # turn on
                lh.writeCharacteristic(0x12, b'\x01')
            else:
                # turn off
                lh.writeCharacteristic(0x12, b'\x00')

In Ubuntu, I also put the following in a file named lighthouse.desktop on my desktop and click it when I want to turn them on or off. Make sure to edit the line Exec=/path/to/lh.py with the actual path.

[Desktop Entry]
Version=1.0
Name=LightHouse
Comment=Turn Index Lighthouses On/Off
Exec=/path/to/lh.py
Icon=scanner
Terminal=false
Type=Application
Categories=Utility;Application;

This actually works better for me right now than the semi-broken Windows power management.

Also, make sure to set chmod u+x on both the .desktop file and lh.py.

I know this code is really old, but has anybody had troubles with this error?
Traceback (most recent call last):

It's a really frustrating issue, and it happens even with a different bluetooth adapter

Yes, run the command as root, or use setcap on bluepy
sudo setcap cap_net_raw+e /home/waylonflinn/.local/lib/python3.8/site-packages/bluepy/bluepy-helper
sudo setcap cap_net_admin+eip /home/waylonflinn/.local/lib/python3.8/site-packages/bluepy/bluepy-helper

Ok thanks now it doesn't make that error anymore. But looks like my lightouses don't seem to care 😢
The script exits without any error but the stations do not start

Update: just noticed the script is supposed to say when it found a lighthouse. But I'm getting no output whatsoever, so i guess it's not finding them

Hi,

Please take look at https://github.com/DavidRisch/steamvr_utils, it expnads on this script, and maybe it will work for you.

Fixed the problem, I forgot my base stations where 1.0 and not 2.0 so it would not be able to find them anyway. https://github.com/risa2000/lhctrl this is the script for 1.0 if anyone is interested
Thanks for the help :)
