A disconnected device can have two states: offline and unknown, for example in my config depending on whether it simply stops sending data or closes the gprs connection / sessions. Why does queued commands only work for offline status devices ? and can it be changed to queued commands also for devices with unknown status.
After sending the command to the device with the unknow status, I can see confirmation that command is sent - I don't know where ...
Unknown status essentially means that there is a network connection between device and the server, but device hasn't reported any data for X minutes. Because there is a connection, we can send it.
