System Uptime

leader21

Here’s a device that tells you the actual system uptime.

create a script in your homedirectory called uptime.sh :

#!/bin/bash
# uptime.sh
# get uptime from /proc/uptime

uptime=$(</proc/uptime)
uptime=${uptime%%.*}

seconds=$(( uptime%60 ))
minutes=$(( uptime/60%60 ))
hours=$(( uptime/60/60%24 ))
days=$(( uptime/60/60/24 ))

echo "$days days $hours hours $minutes minutes $seconds seconds"

then you can use your device like this :

    {
      "id": "system-uptime",
      "name": "System uptime",
      "class": "ShellSensor",
      "attributeName": "Uptime",
      "attributeType": "string",
      "attributeUnit": "",
      "command": "sudo bash /home/pi/uptime.sh",
      "interval": 60000
    },

you can leave the seconds away at the echo in the script.
the gui will show up more cheerful on mobile devices.
