External URLs - Execute a piston from elsewhere

Any piston can be run from any place that you are online. A few possibilities are:

• Clicking a link in a SMS message
• Clicking a link in an email or HTML document
• Opening a URL directly inside any browser
• HTTP GET request from any app with that capability
• HTTP GET request from any OS (Windows, Android, RPi etc.)
• HTTP GET request from another SmartThings hub (IE: House to House)
• Command prompt / batch file / macro tool etc.

Each piston has a unique URL, which can be found at the very top of any piston -->
(Anyone that knows this URL can trigger that one piston whenever they want to, so this URL should be kept private, or only shared with those whom you trust)

So, for example, if you wanted a piston in your vacation house to trigger a piston in your main house, then the vacation house can make a web request like this:

... and the piston in your main house would trigger a moment later.

Generally speaking, the piston that is getting triggered by the external call should have no triggers (lightning bolts).

Once the piston is saved, you should see this up top:

One of the benefits of having no triggers is that this piston can be triggered from multiple locations and different events.
