To increase your flexibility when applying GPS trackers at sports events we developed the "close after"-parameter for messages. Now, there are three options on how the message interacts with the device which is remotely connected to our tracker management (https://racemap.com/admin/trackers/).

• Before "planned at"-time the message is not sent to the device. 
• Within "planned at"- and "close after"-time the message is sent to the device, as early as the device is connected to the tracker management.
• The message that can't be sent until "close after" becomes inactive (timeout) and won't be sent anymore. The new parameter for messages prevents unintentional "shut down"-commands that could not be sent in time.
