“We use our garage more like a main entrance to the house, because using the actual front entrance tracks a lot of dirt into the house due to the poor layout. During the rainy season here on the west coast of Canada it’s even worse. Our garage door opener only came with two remotes and while we can buy more remotes, I though it would be better to have a WIFI based remote that can be used from a smartphone. I didn’t want a WIFI enabled opener that requires a connection to the manufacture server or anything that could allow the door to be opened remotely (far away from the house). The solution I came up with uses a custom Android app that connects to our WIFI and communicates with an ESP8266 based board that can only connect to our WIFI as well. Once you are within WIFI range of the house, you can use your phone to open the door.”
