SABnzbd download indicator

Control panel for the download server.

A gadget with ESPDuino and 4 LEDs indicates the status of the SABnzbd process.
The LEDs show if it is downloading, repairing or unzipping.

On the PC where SABnzbd runs (which is a separate server for me, which is upstairs in the attic) I run the following Bash script:

#!/bin/bash



while :

do

  IsPar2=$(pidof par2)

  if [ $IsPar2 ]; then

   echo "Par!"

   IsPar2="1"

  else

   IsPar2="0"

  fi



  Unzip=$(pidor unrar)

  if [ $Unzip ]; then

   echo "Unzip!"

   Unzip="1"

  else

   Unzip="0"

  fi



  #Here is the API key of your SABNZbd:

  url="http://192.168.0.104:8080/sabnzbd/api?mode=queue&output=json&apikey=75c7061c803441apikeyded356951b8d"

  status=$( curl -s "${url}" | jq .queue.status )

  if [ "$status" == '"Downloading"' ]; then

   echo "Downloading!"

   status="1"

  else

   state="0"

  fi



  #Invoke ESPDuino:

  Url="http://192.168.0.87/set?par2=${IsPar2}&unrar=${Unzip}&download=${status}"

  wget --spider $Url



  sleep 10 #Must be less than 15 seconds because after 15s the error lamp will turn on

done

Start automatically by placing in /etc/profile.d a file downloadindicator.sh (made executable with < b>chmod +x downloadindicator.sh) with the following content:

#!/bin/bash

/home/marcel/status &

If you log in once with SSH, the script will also run, which is a disadvantage because then you have to run it twice.
