This flow gives you multiple options to stop a runaway flow.
1. You can just start this flow directly with the "Emergency Stop" beginning block. (You could also set this as a widget.)
2. You could have a quicksetting button that can be used to stop all flows. (Don't forget to move a quicksetting button to active.)
3. You can send "AutomateStopFlows" in a txt message from any device (or a selected number if you choose.)
Starting this flow from within the Automate app is sometimes not possible if you have a looping flow.
I recommend setting a widget or quicksetting.
The 3rd option is generally a good last option before booting to safe mode and uninstalling automate.
