Domoticz

• Activate a presence switch if the phone is within a certain radius from your home
• Do a reverse address lookup and log the current whereabouts (address) of each phone in a dummy tect device, along with the distance from home

1. Activate Find My iPhone on all phones you want to keep track of (usually this is already standard on)
2. Download a lua JSON decoder, e.g. this one: http://regex.info/blog/lua/json and copy the file (json.lua) somewhere where it can be found (in my case this was /usr/local/share/lua/5.2/). I think you can also append a path after the "require" command in the script below.
3. Create a dummy switch named "iPhone Person1" for each iPhone you want to track (where "Person1" is replaced with the name of the person). Also create a dummy text device for each iPhone named "Position Person1" (again replacing "Person1" with the person's name). If you want (and haven't already done so), configure one or more notification services, then you will be informed when someone leaves the house or comes home.
4. Create the following script and put this e.g. in "~/domoticz/scripts/lua/script_time_checkphones.lua"

   Code: Select all

   -- Script to check the location of multiple iPhones every X minutes,
   -- test if they are "home" and represent this using virtual switches
   
   commandArray = {}
   -- polling interval in minutes (1-59), setting this too low may drain the phones' batteries
   interval = 5
   local m = os.date('%M')
   if (m % interval == 0) then
   
     json = require('json')
   
     -- Array of users to be checked
     users = {
               Person1 = {username = "[email protected]" ; password = "password1" ; devicename = "iPhone Person1"};
               Person2 = {username = "[email protected]" ; password = "password2" ; devicename = "iPhone Person2"};
               Person3 = {username = "[email protected]" ; password = "password3" ; devicename = "iPhone Person3"}
             }
     -- The latitude and longitude of your house (use Google Maps or similar to find this)
     homelongitude = 1.23456789
     homelatitude = 9.87654321
     -- Radius (in km) which will be used to determine if a device is at home
     radius = 0.5
   
     function address(longitude, latitude)
       command = "curl -s https://maps.googleapis.com/maps/api/geocode/json?latlng=" .. latitude .. "," .. longitude .. "&sensor=false"
       local handle = io.popen(command)

             end
           end
         end
       end
     end
   
   end
   
   return commandArray

   Replace the following data with your own:
   • The value of "interval" (number of minutes between polls)
   • The values in the "users" array. Replace "Person1" etc. with the name(s) of the person(s) and fill in the credentials. The device name is the name you gave each iPhone during its configuration. This name has to be filled in exactly right (note the use of capitals etc.). You can add as many users as you want in new lines (pay attention to the correct placement of brackets, parentheses etc.).
   • The "homelongitude" and "homelatitude" values (the position of your house)
   • The value of "radius". This is the radius around your house (in km) to call something "at home". Don't choose this value too low, this could lead to intermittent "left home" - "came home" events since the GPS accuracy is sometimes limited.
   • (optional) I put some code in the script to remove the text "Netherlands" from the address to keep it compact. Change this into your own country if you want.

this is just the thing I've been looking for, thanks! All apps I've tested that use a geofence have been so far very unreliable, I hope this approach solves it! Set it up yesterday and seems to work well for one of our phones, for some reason the other reports currently "offline" in Find my iPhone app and thus the script also gives an error:

Code: Select all

2016-09-13 13:20:07.859 Error: EventSystem: in PresenceDetection: [string "commandArray = {}..."]:51: attempt to index field 'location' (a nil value)

This got me thinking that what would be the best way to build some error checking to the script? Maybe even something to keep track when was the last successful update, what do you think?

print(position)

print(lon)

Your error seems to be in line 52, if you didn't add or remove any lines from the script that is where the string is constructed to put into the dummy text devices:

Code: Select all

position_text = string.gsub(position, ', Netherlands', '') .. ' (' .. (math.floor(distance*10+0.5)/10) .. ' km)'

Can you confirm this?

Please add a line between line 51 and 52:

Code: Select all

print(position)

Does it print the address(es) of your devices in the Domoticz log every 5 minutes? (You can temporary set the interval to 1 minute to speed up the debugging process)
If not, add two lines between line 49 and 50:

Code: Select all

print(lon)
print(lat)

Does it print the coordinates of every phone?

Can you confirm that line 52 (now line 55) is indeed the line I mentioned above (starting with "position_text = ...")?
Please also add a line after th eline starting with "distance = ...":

Code: Select all

print(distance)

Does it print the distance? If not the error could be in this formula. If the distance is nicely printed, you could replace

Code: Select all

position_text = string.gsub(position, ', Netherlands', '') .. ' (' .. (math.floor(distance*10+0.5)/10) .. ' km)'

with

Code: Select all

position_text = position

Just to check if the error is in that line.

mcmikev wrote:Thx for the quick response. No error anymore.

But I cannot see if it works either.

I am at home and the virutal switch is off and stays off. When I turn it ON then it remains on.
The virtual text switch also stays at Hello WORLD.
I named the switch iPhone Mike and that is also what is in the script.
Should the text dummy alsy be named Position Mike or iPhone Mike or remain it as Position Person1 ?

PS: Not sure if it matters but I have no icloud email but my own personal email but I guess that this is not the reason why.
