**What is Heartbeat?**  
Heartbeat defines how often the device sends a status update to the server, even when no sensor data has changed. It helps confirm that the device is active and communicating.

- **Example**  
  If the heartbeat is set to `15 minutes`, the device will send a signal to the server every 15 minutes, regardless of data changes

A lower heartbeat interval provides more frequent status checks but may increase power consumption on battery-powered devices.s

Useful for offline analysis, compliance, or record-keeping in field deployments.

>Note: External flash memory is optional. Please verify whether your selected variant includes flash memory before placing your order
