● ECL - ECL level. This parameter is a good indicator of the signal quality. The lower, the better.
ECL 1 or 2 may significantly reduce the battery life
● Cell ID - ID of the cell in to which the device is connected
● Last communication timestamp - timestamp of the last successful communication. All the
information on this card is refreshed during the communication / self check.
● Last status check timestamp - timestamp of the last self check. Self checks are performed on
the startup or may be performed on server’s demand. All the information on this card is refreshed
during the communication / self check.
Battery status
Efento loggers will inform you about the low battery level both on Efento Cloud platform and in Efento
Logger mobile application. Once a “low battery” status shows up, you will have 2-3 months to replace
the battery.
Efento loggers allow you to get the detailed information about the battery voltage and operation
parameters. In order to get the detailed battery parameters, connect to the logger with Efento mobile
application -> three dots in the upper right corner -> “Battery status”.
You can get the following information:
● Battery status - information if the battery has to be replaced (“LOW”) or not (“OK”)
● Battery Voltage - current voltage of the battery in mV
● MCU temperature - current temperature of the processor
● MCU min temperature - lowest temperature of the processor
● MCU max temperature - highest temperature of the processor
● Battery min voltage - lowest voltage of the battery
● Battery reset timestamp - beginning of the battery monitoring period
Installation mode
In the installation mode, the device continuously communicates with the network and Efento Cloud for
300 seconds (5 minutes), refreshing the signal strength and connection parameters. Starting the
installation mode allows you to check whether the logger correctly logs into the network and whether the
signal strength of the NB-IoT network is sufficient for the correct operation of the logger. Launching the
installation mode is not required for the correct device configuration. After starting installation mode, the
user can check:
● Seconds left - the number of seconds remaining until automatic exit from the installation mode
● Signal strength - NB-IoT signal strength in tenths of dBm. -120 is taken as the extreme value. If
the signal strength is below this value, the device may regularly lose connection and not be able
to correctly send data to the server
● Signal Quality - parameter defining the signal quality
● Last data fetch Timestamp - date and time of the last communication with the network. All
parameters related to communication with the network have been refreshed at this time
● Registration Status - network connection status. There are three possible statuses:
