Additional Information

Guys, I'm running the MLB Scoreboard on my raspberry. I normally start the scoreboard by jumping in the mlb-led-scoreboard folder through cd mlb-led-scoreboard and then I run the command from above which works as it should.

I got myself a Homeassistant and I'm trying to create an automation that connects both the HA and my scoreboard.

All I need for this is just one command. So I tried using this command here:

sudo python3 /home/pi/mlb-led-scoreboard/main.py --led-rows=32 --led-cols=64 --led-chain=4 --led-gpio-mapping=adafruit-hat-pwm --led-pixel-mapper=U-mapper --led-brightness=30

I get this message in return:

pi@raspberrypi:~ $ sudo python3 /home/pi/mlb-led-scoreboard/main.py --led-rows=32 --led-cols=64 --led-chain=4 --led-gpio-mapping=adafruit-hat-pwm --led-pixel-mapper=U-mapper --led-brightness=30 ERROR (04:04:23): Untrapped error in main! Traceback (most recent call last): File "/home/pi/mlb-led-scoreboard/main.py", line 169, in main(matrix, config) File "/home/pi/mlb-led-scoreboard/main.py", line 41, in main config = Config(config_base, matrix.width, matrix.height) File "/home/pi/mlb-led-scoreboard/data/config/init.py", line 26, in init self.preferred_teams = json["preferred"]["teams"] KeyError: 'preferred'

How would the correct command be?

Don"t know if this will help or not, I am running s similar setup. First off I start mine from the mlb-led-scoreboard directory. My start command is "sudo python3 main.py --led-gpio-mapping=adafruit-hat-pwm --led-rows=64 --led-cols=64 --led-chain=2 --led-brightness=80 --led-slowdown-gpio=2 --led-no-hardware-pulse=2" I am currently running 3 similar boards with same commands other than matrix size and rows and cols. Hope this helps.

The command to start the scoreboard has changed in v8 compared to v7 and under.

https://github.com/MLB-LED-Scoreboard/mlb-led-scoreboard/blob/master/README.md#usage

sudo ./main.py <FLAGS>

Hi @ty-porter, that might be the missing part in my project :)

I will try it as soon as I get home.

Thanks in advance

Thanks for the tip, that worked.

Don't think that this command will work tho:

sudo python3 /home/pi/mlb-led-scoreboard/./main.py --led-rows=32 --led-cols=64 --led-chain=4 --led-gpio-mapping=adafruit-hat-pwm --led-pixel-mapper=U-mapper --led-brightness=30

I need one command that starts the scoreboard.

Right now I'm doing two commands by 1) going into the right folder (cd mlb-led-scoreboard) and 2) start it (sudo python3 ./main.py ...) That needs to be put into just one command.

It will not, you need to use the command I showed above. You do not run this via python3 now. The script itself is executable and locates its own Python.

sudo ./home/pi/mlb-led-scoreboard/main.py <flags>

Can say with confidence that it does not.
