Find My iPhone implementation in LUA script

[Egregius]

Add some prints to the script and watch the logfile.

Hi again
my bad guys, I'm running on Windows and that's probably why it doesn't work...

Never used lua or curl before so it will probably take a while for me to find the OS-dependent parts.

That explains a lot .
Not sure if there are alternatives to curl that are standard present on Windows systems. But you could probably simply install a curl version for Windows: https://curl.haxx.se/download.html
I haven't tested it, so no guarantees

Do you know you can (ab)use the same service to sent text messages to ios? They even make sound when the phone is in do not disturb mode or silent.

[G3rard]

Could it be that you need to manually update the text sensor once it a text like "Westlaan 401-407, 8800 Roeselare (6.7 km)"?

I guess you could be right! At first, I didn't have the check that it was only updated when the difference with the previous position was large enough. I get the previous distance from the contents of the text field, so when that doesn't contain "(x.x km)" it will never be updated. I have added a line in the script

Code: Select all

if prev_distance == nil then prev_distance = 1000 end

See original post where it needs to be placed. Can you let me know if this helps?

Thanks for this script!

I had to change the line

Code: Select all

prev_dist = tonumber(string.sub(string.match(otherdevices['Position ' .. user], '%(.*%)'), 2,-5))

to

Code: Select all

prev_dist = tonumber(string.sub(string.match(otherdevices_svalues['Position ' .. user], '%(.*%)'), 2,-5))

to get this working.

Nice, do you have some more information available on this?

Strange, here it (also) works without using svalues. Makes you wonder how two Domoticz systems can behave so differently? Are you perhaps on a stable (older) version?

Only in PHP
It's included in my pass2php script (http://egregius.be/tag/domoticz/ and https://github.com/Egregius/PHP-Custom- ... r-Domoticz)
Once operational it's enough to have a line like this:

Code: Select all

ios('test message with high priority');
 

Then the message is sent as if it would be sent from the findmyiphone service, because of that it always makes sound. Ideal for those really important messages like movement in the living room while you're sleeping and the phone is on do not disturb mode. Mine is always in that mode during the night.

Well i still have the issue as my post said

[Egregius]

Place the json.lua file in one of the folders where it's searching. If the folder doesn't exist just make it.

ex
/usr/local/lib/lua/5.2/

sudo mkdir /usr/local/lib/lua
sudo mkdir /usr/local/lib/lua/5.2
sudo cp /home/pi/domoticz/scripts/lua/json.lua /usr/local/lib/lua/5.2

Well its not the JSON file thats the issue. Check this post and see the rest of the posts

I think I see what the problem is. I was looking at the wrong line all the time, line 56 in your script seems to be the line with the UpdateDevice command, right? In that line there is a space missing after 'iPhone'. I had that typo for a brief moment in my original post, but corrected it as soon as I saw it. Apparently you copied the code before that. Let me know if it works now! If so, please remove the "position_text = position" if you want distance info in your text devices.

Well, i copied the script again and got new errors

Its getting closer....

[mcmikev]

I still have some strange behavior.

The script seems to be running fine. I have added some print('debug') lines to see where the scripts stops or fininshes.
It looks like te whole scripts is being run but nothing is changed (switches or text swtich).

What could be the issue for that?

This is de "debug" for the script.

Hope someone can tell me what is going wrong. No errors are being given.

Thanks.

[Egregius]

You don't have any print in the if value.name == credentials.devicename block. I would one there.
Also remove the -- before the print ('iPhone... line.

[mcmikev]

I have added some more print lines none of these are shown in the log

Maybe some extra information : I run on RPI2B with domoticz image.

Ok, sorry, missed an "end" in line 54, see updated original post again.

The problem is that I have been editing it based on feedback from this forum and my own improvement ideas, but without testing. I do test things in my own version of the script, but that's already different again since I keep on trying and adding stuff. Classic case of bad version control. I don't have a lot of experience in programming, now learning these things the hard way . Sorry for the inconvenience!

From your debugging output I conclude that getting the info from Apple using curl and json-decoding works fine. But if the "print(lon)" and "print(lat)" do not show up in the log, that must mean that the "if value.name == credentials.devicename" is never true. Are you sure you typed the name of your iPhone correctly in the "users" array? Are there any special characters in it maybe? You could adda a print(result) after "local result = handle:read("*a")". That should print a very long string in the log with all your device info. Try to look for your device name in it. Does it show up, and how is it exactly spelled?

[mcmikev]

Just discovered that It is not the switch name but device name of the iphone

Changed that and now I get more
