[SOLVED] Flightradar24 - aircraft position

Hi there,

anyone who implemented somting like an aircraft tracking (with map view) for specific flights?

Idea:

  1. Flight schedule entry in my calendar
  2. OH will check for flight number
  3. OH will request flight data from the web
  4. Display position, speed and delay on a map.

Work has me traveling more these days. Something like this would be cool for the kids to be able to see when i am flying.

That is exactly what I am after :slight_smile:

I’ve found this thread and it looks like we’re not getting any API from FR24 anytime soon.

There’s however libhomeradar (linked in same thread) which allow to 24 requests per day.

This might help you get it started :wink:
Don’t forget to post a tutorial afterwards!

I have been playing around a little bit with this. I have another trip coming up tuesday so I will be out of pocket again. But I do have a dev api access key setup for flightaware. the free one is giving me basic flight info (departure, arrival, percent of the trip)

I think to start with I am going to have a couple php files that I can hit via the http binding to get some status. Then maybe work on a binding.

Ill keep you posted as I make progress

Any update / progress?
:blush:

Have you been able to proceed?
I just registered for the free basic access as well and wonder if you could share some of your findings.
Thanks in advance.

Not as much as I had hoped. But here is what I have.

then

        var url = transform("REGEX", ".*\(.*?\).*", "Flight to Atlanta (DL 1961)".toString())
        logInfo("Flight","Flight:" +  url.toString())
}
end

The php file i used for test is here.

That way I wasn’t burning up a bunch of my calls to flightware.

The real page is

<?php
// get flight status on flight
$options = array(
                 'trace' => true,
                 'exceptions' => 0,
                 'login' => 'apilogin',
                 'password' => 'apikey',
                 );
$client = new SoapClient('http://flightxml.flightaware.com/soap/FlightXML3/wsdl', $options);



$params = array(
  "ident" => "UPS782",
  "howMany" => 1,
  "offset" => 0 );

$result = $client->FlightInfoStatus($params);
print_r($result);

So there is some work left to do. In the index page you can see the “ident” is hard coded. That needs to be changed to most likely to the item “FlightNumber_String” and that would put your flight number in.

I was working on that part with the rule “detected flight”

What I was trying to do was do some regex that would search for flight number in a string, that string would be my appointments since google was putting my flight numbers on my calendar automatically.

However, if you do something like just put in a string where you could type in your flight number and the date you are flying you could have the cronjob match that string and turn on the “Traveling_Switch” and then the rest of the rules would fire.

There was another item type i never got around to doing.

String FlightAircraftImage

Then in the rule it would update like:

FlightAircraftType.postUpdate(transform("JSONPATH", "https://www.skybrary.aero/images/$.FlightInfoStatusResult.flights[0].aircrafttype",FlightOriginAirPorttmp).toString)

Or whatever the format is. Not actually doing this on my server. But it seems the site skybrary.aero has ALOT if not all the aircraft type images stored based on their names.

I stopped working on this as my job duties changed and I don’t travel much (if any) like I was.

I hope this helps get you further and would love to see any progress you make or add!!

As there are some trips upcoming, I would like to proceed with this (didn’t have enough time yet :frowning:

Did you succeed? Are you able to get the aircrafts position as well?

I started to use your code and this pushed me forward significantly.

I guess I will have it done soon.
However, I miss one function on flightaware:
Checking for the unique flight id (faFlightID) on a specific date.
the API v3 does not allow GetFlightID (yet)

Anyway, I will try to find a workaround and will post the results here.

I wish I was still traveling like i was. but i haven’t had a flight in just over a year. Can’t wait to see what comes of it.

I can’t complain :wink:

Although the good part for me:
My wife is travelling long haul flights as well.

emougjh time to troubleshoot :wink:

lol. that was something that made it weird, wasn’t able to work on it while in the air. which would have been so amazing!!

So i used to just pick random flight numbers lol of flightaware that were on cross country trips.

If you start doing any UI stuff like on the dashboards i would love to see. That was my hope, I wanted to have on one of the touchscreen tablets a habpanel button that would light up if it was a travel day. Then show all the details and import the picture of the type of plane ect for the kids.

Great idea!
I will consider this after getting the main points done.

I am almost done.
However, I did not find a link to retrieve the aircraft type pictures.
After the next iteration and check, I will post the stuff here.

Here it comes.
Please let me know if you have questions or better suggestions for improvments.

What it does:
Whenever one of my calendar entries changes and an entry is detected with “Flug” (=flight), the information is extracted and used for a cross check with flightaware. The nearest flight is used for further processing.
Because the flight number is not unique and will re-occurr every day, I cross check this with the departure time in my calendar.
Then I constantly monitor the actual time vs. the departure time and track the flight using flightaware during the flight.
The location will be used for a map display.

	}
end

Please let me know if you have ideas for improvement.
Especially the part in the flights rules, where I check the departure time, would be possibly better handled by a loop - but I did not figure out how, yet.

And my Habpanel View

I have another idea / need for improvement:
After a flight has landed, the next upcoming flight will not be used unless the calendar entry changes.

So, how to cycle through all the calendar entries (CalName1 to CalName14) to check for “Flug”?
Any suggestions are greatly appreciated.
