I wanted data redundancy available online so using the OH REST api and cURL I wrote a bash script to export my OH items (last state) to a Thingspeak channel every 15 minutes (script writes info to file in local directory which you can add to crontab).
- thingspeak channel established (write API key)
- openhab item names
- ability to query OH server using OH REST
Please see my repo for the script
