The purpose of the little bash script is to monitor a group of TheThingsNetwork gateways and report an alarm when one of them is down / up. The trigger is reported over IFTTT webhook so it is easy to get an email, a phone push or a light color changing on a such event with the IFTTT integration.
To use the script, make the configuration, run it with a cron at the desired frequency. The script is using bash with no more depencies than curl and the ttn cli.
- You need to download the TTN CLI - read this post on configuring the CLI client
- You need to create a webhook on IFTTT - read this post on how to configure an IFTTT webhook
- clone / copy the script into the same directory as the TTN CLI
- make it executable
chmod +x ./monitor.sh- edit the script and update the parameters:
- The IFTTT_KEY see the post about IFTTT webhook setup
- The IFTTT_EVENT is the name of the IFTTT event like "If Maker Event "XXXXXX", then..."
- List your gateways to monitor in the gatewaysConf
- Eventually change the TIMEOUT_S in second if your gateway is not stable
- add an entry in crontab
*/5 * * * * root ( cd /path/to/the/script/ ; ./monitor.sh )
- relaunch the crond deamon
If you want to change the list of the monitored gateways, you need to make it in the monitor.sh file and you also need to remove the /tmp/LoRaWanGwMonitor.tmp file.
