Its part of a broader control and automation scheme that involves raspberry pi and node-red. I tap a http widget on my android phone and open the door. No opening a dashboard ui or starting some other program. its right there on the home screen. the pi running node red automates all kinds of other things it has graduated from opening a garage door to automating most things in the house. it began as a simple webserver that put the doors on the network (github andrewshilliday garage door project) but I would still have to open the webpage to get to the door controls (lame). separately, I wanted to automate some outdoor lighting to turn on at sunset and researching that I discovered the shelly1 and it was ON. I learned about mqtt and node red soon after then realized I already had a pi with node red already installed on it and it had relays wired to it already for opening the door so I quit using shilliday's door opener and began using node red to do it. it's been a labor of love ever since.
