Cant run commands on Raspberry Pi 3B+

rtn17

Hi !
I successfully setup my Raspberry Pi 3B+ but can't run any commands. My TriggerCMD is linked, too. Alexa is finding the "device" but when I run the command nothing happens. The original commands also didn't work for me.

I want to control one LED Strip through Alexa. My config.json looks like following

[
  {"trigger":"strip","command":"sudo PYTHONPATH=".:build/lib.linux-armv7l-2.7" python rpi_ws281x/python/examples/strandtest.py -c","ground":"background","voice":"strip","allowParams": "false"}
]

The path of the json file is /root/.TRIGGERcmdData/commands.json

Thank you in advance!

You need to escape the quotes (using backslashes) in your command because they're inside other quotes (for the json). Please try this instead:

[
 {
  "trigger": "strip",
  "command": "sudo PYTHONPATH=\".:build/lib.linux-armv7l-2.7\" python rpi_ws281x/python/examples/strandtest.py -c",
  "ground": "background",
  "voice": "strip",
  "allowParams": "false"
 }
]

Thank you very much!

I changed the command and added the absolute path.

[
 {
  "trigger": "strip",
  "command": "sudo python /home/pi/rpi_ws281x/python/examples/strandtest.py -c",
  "ground": "background",
  "voice": "strip",
  "allowParams": "false"
 }
]

Now it's working.

@rtn17, awesome. You're welcome.
