Arlo cameras and sensors (entities) not showing up

I’m going to do the same. When you disabled did you just comment out

arlo:
  username: !secret arlo_username
  password: !secret arlo_password

or do you also have to comment out all the groups and sensors?

On a side note, I’m fairly certain using this integration causes the batteries to drain much faster than normal and I don’t see a way to control how often HA polls the cameras.

Disable sensors and cameras as well.
