To use the Spot tracking mode (only for devices registered with findme.spot) you must set up a public shared page on the Spot website. When you set up the page, make a note of the last part of the URL after "glId=" (copy and paste). Edit your database entry on this site, adding 33 character string from the URL to the "shared page" field. Once you have that your database entry should show a link to the shared page, and a link to the XML data that is used to generate the map. If they work, you should be able to enable your Spot for tracking.
Polling occurs every 10 minutes, and data may be delayed.
Devices registered with trackme.kiwi get the data delivered directly to the tracking system. This reduces delays to a few seconds and means the only noticable delay is the refresh cycle on the browser (two minutes).
