# Loggers list
The **Sensors** tab displays all loggers currently within the range of the Efento Gateway. For each logger, you can view:
* Serial number
* Name
* Status
* Current measurements
* Signal strength
* Measurement interval
* Timestamp of the last communication
* Information on whether measurements are buffered in the gateway’s memory (used when connectivity issues occur; the gateway will automatically resend missing data)
A search bar is available above the list, allowing you to quickly locate a logger by its serial number. You can also use the filter buttons () to display only loggers with specific statuses (e.g., downloading, OK, lost, low battery, issue, encrypted).
If the Efento Gateway is configured to work with **Efento Cloud**, it automatically synchronizes all measurements stored in its internal memory with the cloud. Loggers whose measurements are currently being buffered are highlighted in blue. If a logger is bounded, the gateway will also automatically download data from the logger's internal memory whenever the logger goes out of range and reconnects later, ensuring no measurements are lost. By selecting a logger, you can view its data as a chart or table or export it as a **TXT** or **CSV** file.
