Inventory number of items, things, rules

[brononius (Ben)]

How many items do you have, how many lines of code, how many…?

This to have a kind of view on my openHAB installation.

• Example:
  

In the future I want to add

• Number of different binding.
• Finetune my script a bit so empty rules, and comments, are not taken into account. Important for exact numer of items

How I did this?

1. Small script for each calcuations.
   This is just an example for the numer of items lines.

   cat /etc/openhab2/scripts/numberItems.sh

   #!/bin/sh
   localUrl=http://localhost:8080/rest
   localHeader="Accept: application/json" 
   NumberItems=$(curl -s -X GET --header ${localHeader} ${localUrl}/items?recursive=false | python -m json.tool | grep name | wc -l)
   echo $NumberItems
   exit
   

2. Then I’m using the command REGEX in Things:

   

3. For my items

   String	numberItems	"Number of Items [%s]"		 {channel="exec:command:numberItems:output"}
   

4. And in the sitemap

   Text item=numberItems
   

Suggestions or comments are more then welcome!
