Running pylacrosse on hassio

Hi

I am very new to home assistant and have recently installed hass.io to a RPi2. I am using lacrosse sensors and have one running and reporting to HA. Now I want to find them all which should be possible by running sudo pylacrosse -d /dev/ttyUSB0 scan, but how do I do that on the raspberry? I have installed the ssh add on, and logged in, but I can’t figure out how to run this. Can it be done?

Hi,

i have a freshed installed HAOS on my rpi4 and i will get the ID from my lacrosse devices.
If i try to get the ID with the pylacrosse command, i see the message: command not found.

How can i install the needed Software?
