External vs internal piston URL


I use Blue Iris to fire Webcore pistons when my cameras detect certain objects. After moving to Webcore on Hubitat, I expected everything would run locally. But when I look at the URL used to fire a piston from an external source, it starts with this:


I was expecting an internal IP address. Does anyone know why I’m not just sending the request over my local network? Thanks for any info anyone can provide.


If you on HE:

  • go to HE console -> Apps -> select your piston

Hit ‘Test run this piston’

The screen will show you both the cloud and local URLs for the piston.


That works. Thank you.
