Hi,
Greetings
Where can I find a simple and understandable description of the data sent from the device to the server, along with an explanation?
FMB920 and other teltonika device is using codec 8 and codec 8 extended protocol for data sending and codec 12 for sending GPRS command: Codec - Wiki Knowledge Base | Teltonika GPS (teltonika-gps.com).
It's trying to decode the data and it's too hard... I use my own traccar server and it's hard for me to set attributes and alarms. I need to understand what the FMB920 server sees, how it is written, and what the specific values mean. I read the forum and the manual, but it is incomprehensible to me .
If you want to decode the data easily you can try to use the flespi server here you can get the RAW data and capture AVL parameters: https://flespi.io/#/panel/list/channels
I would like to write an attribute that will, based on the data from the FMB920, trigger an alarm that someone is trying to remove the device from the vehicle. Maybe such an attribute already exists?
Please check this wiki page for unplug detection: FMB920 Accelerometer Features settings - Wiki Knowledge Base | Teltonika GPS (teltonika-gps.com)
I apologize for the number of questions. Your textbook is too extensive and hard to understand. The least understandable is the topic of device-server messages just described.
If you want to analyze the data there is specific data FMB920 device and all other teltonika device uses AVL ID for a particular parameter here is the link : FMB920 Parameter list - Wiki Knowledge Base | Teltonika GPS (teltonika-gps.com)

Will the FMB920 device in the absence of GSM coverage save data on the device and then after regaining the range send it to the server? If so, do I need to make any settings in the device configurator?
While offline data will be stored on the flash memory , Once the device goes online it will send the data according to your settings it depends if you select Newest or Oldest.

The device wakes up and starts when you sense the movement of the accelerometer. What information is then sent to the server?
Yes if you enable the sleep mode the device will wake up and send the data to your server once the ignition or movement is detected by the device.
