<!-- hint: Put this in a folder, edit the IP address and port
variable MOON and just above there, the webcam URL
Then in the same folder run (if you want to use 8085 as the port #):
python3 -m http.server 8085
Then in Orca, set your device tab to http://127.0.0.1:8085/mini-dash.html

Simple Custom WPSD remote setup

You need to do the following:

  1. Copy pistar-remote.wd5gnr to /usr/local/sbin/pistar-remote.wd5gnr AND /usr/local/sbin/pistar-remote.wd5gnr.backup (important!)
  2. Copy the files (remote-user-hook-example0, bm_tg.py, gnrcheck) for /usr/local/bin to your /usr/local/bin directory
  3. Edit (don't copy) your /etc/pistar-remote to look like the one below
  4. Copy and Edit /home/pi-star/user-hook-data to fit your needs
  5. Make all the files except user-hook-data executable (e.g., chmod +x gnrcheck)
