How to accomplish ST integration with an 828LM?

I have one of the latest Wifi enabled Liftmaster garage openers and would like to integrate it with ST. I understand I will need an 828LM internet gateway, but as a newbie I’m unclear about how to intergrate it with ST.

I was thinking to use a ST door sensor to detect when it’s open or closed and then use the MYQ app to open it. However, it seems like there has to be a more seamless integration out there. I’m not up to speed yet with tinkering around with the API or adding custom device types yet. So please excuse my novice. I am expecting my ST unit in the mail next week. I would appreciate any guidance on this.
