Windows Service for turning on and off overhead light depending on computer power state

Background

I've been building an electrical engineering workbench, and one feature that annoyed me was the switch for my lights. Instead of fumbling around the power cord, I decided it would be best if they would turn on and off at the same time as my computer. I bought some of these and reverse-engineered VeSync's app to use the smart outlets with just API calls. Then, I built this windows service to call the API depending on the power state; computer turns on, so do the lights. Computer turns off, so do the lights.

Installation

1. Copy the contents of /bin/Debug to a folder of your choice, I like C:\Program Files\Workbench Light
2. In that folder, run the command installutil.exe "Light Service.exe"
3. Edit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Workbench Light in your registry, and add "token" "accountid" and "outletid" string values with the appropriate information.
