 *  version 2 user defineable timeout before checking if door opened or closed correctly. Raised default to 25 secs. You can reduce it to 15 secs. if you have custom simulated door with < 6 sec wait.
 * Version 3. add code to get name of device so messages don't alwasy says garage door for instance if you are using it on a fence gate etc.
 * Version 4 . Port to Hubitat. 
*  version 4.1 change doorcontrol to virtualgaragedoor for hubitat.

* lgk 2/24 v 4.2 add option to blink a light x times with y delay between each blink before closing

The simulated device will then control the actual garage door. In addition, the virtual device will sync when the garage door is opened manually, \n It also attempts to double check the door was actually closed in case the beam was crossed. ",
