Blynk Home Automation System Script (Scripts/user/home_automation.script)

BatchFile
Here is the Script we created which builds our Blynk enabled home automation system. Some of the values (INSTEON addresses, email addresses and passwords, cell phone address, Blynk authorization tokens, timer longitude and latitude) will need customization to run on another system.

We've added spacing and comments (text strings that begin with a '#') to make the Script easier (for humans) to read. These will all be ignored by the Virtual Wiring system, so this can be your final, runnable script.
