Smartthings on LAN for Home Assistant

About Smartthings on LAN

This is a Home Assistant integration of SmartThings. If you do not use both, this is of no use to you. This code uses the standard builtin smartthings but tweaks a bit to remove requirement of incoming webhooks. Secure incoming webhooks are difficult to setup. The requirement also eliminates need for Duck DNS and nginx addons.

Further it sends commands and recieve events on LAN. This makes it faster and more resilient of internet connection. It recieves events from cloud as well but forwards the first recieved (typically LAN) and discards the duplicates.
