Get Growl Notifications following a UK Gov petition
For those of us in the UK, there are occasionally some interesting petitions that are started on the UK Government petitions website: https://petition.parliament.uk/
If you want to keep an eye on it without going to the page and clicking refresh once a day, you can easily set up a Node-Red flow to follow the number of signatures on the petition.
In this flow, I'm using the growl node to get notifications on my Ubuntu desktop, but you could quite easily substitute it for a PushBullet / Pushover / MQTT node as well!
