IFTTTTrigger=FWGReboot

Set up

1. ssh to your Firewalla. If you don't know how, see firewalla's instructions.
2. Put fg_reboot.sh in ~/.firewalla/config/post_main.d. If post_main.d doees not exist, create it first.
3. If you are going to use IFTTT for notifications, add the rebootdata.txt file as well and edit rebootdata.txt to have your IFTTT key and trigger. (only required if you are using IFTTT). IFTTT should be configured with a Rich Notification notification, not JSON.
4. Create an IFTTT applet with a Webhook (trigger) that sends a notification.

Sample notification

Here is an example of the IFTTT applet that sends a notification and an email.
Every time Firewalla updates or reboots it will log to /data/fwg_reboot.txt and send a notification unless you leave the IFTTT key empty.

Notes

• Currently only the last 100 updates/reboots are stored. You can change this by updating the "retention" variable.
• Tested on Firewalla Gold, Purple, and Blue Plus
