This driver implements the "Switch" and "Contact Sensor" capabilities. It is used to create an HTTP POST, PUT, or GET to a user defined IP Address and Port. I updated this code from the orginal use-case to allow for a "Custom" body text option.

Instructions for use

Create Hubitat Driver

• Open up the "http-switch2.groovy" driver from this repository (https://github.com/ccruise/hubitat-http-switch2/blob/master/Drivers/http-switch2.src/http-switch2.groovy). Make sure you hit the "RAW" button, then select/highlight all of the source code, and COPY everything (Ctrl-C on Windows, or right click->Copy).
• In your Hubitat Elevation Hub's web page, select the "Drivers Code" section and then click the "+ New Driver" button in the top right corner. This will open a editor window for manipulating source code.
• Click in the editor window. Then PASTE all of the code you copied in the first step.
• Click the SAVE button in the editor window.
