I'm Home!

Turn on the lights when I come home.

How it works

• Get the time of the next sunset
• Query Mist for presence of specific device (in this case, my phone)
• Create applet on IFTTT which listens for tagged emails
• If sunset has elapsed, and phone has just connected to the netowrk
  • send an email to IFTTT with defined tag

Requirements

• MIST Access Point
• Mist API Token
• IFTTT account
• Lat/Long for which sunset is to be calculated (I've used San Francisco in the example below)
• Smart Outlet/Device with IFTTT support
• App password in case using gmail account for emails

Place these in a config file : config.json

{
    "mistAPIToken" : "",
    "siteID" : "",
    "deviceMAC" : "",
    "coordinates" : {
        "latitude" : "37.733795",
        "longitude": "-122.446747"
    },
    "email" : {
        "from" : "YOUR IFTTT email address",
        "pass" : "",
        "smtp" : "smtp.gmail.com",
        "port" : "587",
        "subject" : "#home",
        "to" : "trigger@applet.ifttt.com"
    }    
}

Running

   go install github.com/gurpreetz/imhome
   imhome

Note: config.json need to be placed in the directory from where imhome will run

TODO

• Staggered Mist API Queries (query less often when the sun is up, more frequently near and after sunset)
• Hysterisis - dont turn on the light if i've already been home and phone reconnects to WiFi
