Logger status

Efento loggers collect information about its current status. This information is useful for troubleshooting and solving the connectivity issues. Information about current logger status can be accessed with the Efento Logger application or remotely, from the server.

Cellular network status

Current device’s cellular status can be checked in the “Cellular network status” tab (connect to the logger -> three dots in the upper right corner -> “Cellular network status”). In the tab, you can see the following information:

  • Supported technologies - what cellular technologies are supported by the device. There are two options: NB-IoT or NB-IoT & LTE-M

  • Current technology- what technology is currently in use. For NB-IoT only loggers it will always be NB-IoT, For NB-IoT & LTE-M logger, current technology depends on the technology which is currently in use. Devices automatically switch between technologies, depending on the inserted SIM card

  • Registration status - indicates current network communication status:

    • REGISTERED - registered to the network - this is typical status of the device;

    • NOT REGISTERED, SEARCHING - not registered to the network, searching for it - this status may be seen during device power up, when it did not manage to attach to the network yet;

    • NOR REGISTERED_NOT_SEARCHING - not registered to the network, not searching for it - this status is seen mainly, if there is no network coverage;

    • REGISTRATION DENIED - network did not allow device to register

    • REGISTERED ROAMING - if the device is registered in roaming

    • REGISTERED EMERGENCY ONLY

    • UNKNOWN - all the other states

  • Registration reject cause - if the device is not able to register to the network, the cause is displayed in this field. Reject causes are described in 3GPP TS 24.301 Annex A

  • Signal strength - strength of the signal

  • Communication status - describing current status of communication with the server. Possible statuses: OK, server error, encoding error, socket error, timeout, mismatch, unauthorized, unexpected error, not registered, not supported

  • IMEI - IMEI number of the cellular module

  • ICCID - ICCID of the SIM card in the device

  • IP address - current IP address of the device

  • 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 -> “Power user” -> “Diagnostics” -> “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
