The logic is super simple to build the array for the geojson:

foreach ($GLOBALS['cache']['devices']['id'] as $device)

    {

      if (!$config['web_show_disabled'] && $device["disabled"]) { continue; }

      $lat = (is_numeric($device['location_lat']) ? $device['location_lat'] : $config['geocoding']['default']['lat']);

      $lon = (is_numeric($device['location_lon']) ? $device['location_lon'] : $config['geocoding']['default']['lon']);

      if ($device["status"] == "0")

      {

        if ($device["ignore"] == "0")

        {

          $locations[$lat][$lon]["down_hosts"][] = $device;

        }

      } else {

        $locations[$lat][$lon]["up_hosts"][] = $device;

      }

    }

We then iterate over each lat/lon pair and build the geojson entry for it. If the devices aren’t ending up in the same lat/lon pair, they probably don’t have the same lat/lon values.

Check the location information tab for the device in its settings, make sure the lat/lon coordinates match for all 3.

Hi Adam

Yes, apologies for the lack of detail in my first email, but Markus described the issue perfectly.  The UP/Down count of devices per location is not always accurate on the dashboard map.

For example, in one of our sites, the map displays Up 4 devices, and Down 0

But the actual device list for that location is 84 Up and 2 down.

The location address is the same for all the devices at that site. 

Thanks

Tony

[CAUTION: EXTERNAL EMAIL]

If you hover over a location its number of devices up are not always correct.

Here my map shows 1 device up and 0 down but when I click on this location and get the list view:

It shows me that 3 devices have this location

Hi,

It’s not quite clear what you’re comparing.

Hi

I’ve been having an issue with the number of devices per location not being correct when displayed on the Dashboard Map.  A few of our sites have the correct count, but most do not.  From the list view everything is ok.  The devices accessible and are set to a location that is geolocating to coordinates, but it’s like they’re not being counted properly. 

Thanks

Tony
