The Automatic recovery mechanism runs every day at 2:00 am to recover unreachable commissioned sensors and recommissions them by sending the configured wireless settings to these sensors.
Every day at 2 AM, Manage attempts to recover sensors that have not communicated for the past 12 hours. This could be sensors that have been decommissioned, powered off, or otherwise unreachable. For each lost sensor, Manage will attempt recovery daily for three days and then stop attempting.
When Manage attempts to recover a sensor, sensors that share the same Gateway will not respond to Manage commands for a short period of time (always less than five minutes).
Below is a list of the events generated for the automatic recovery of lost sensors when Manage attempts to recover sensors that have not communicated for the past 12 hours.
- Attempting to find and recover sensors that lost communication: This event is sent at the beginning of the sensor recommission operation for a gateway.
- xx:yy:zz sensor could not be recovered: xx:yy:zz is the sensor's MAC address that failed to acknowledge recommissioning.
- Attempt to recover lost sensors is complete. Discovered ‘NN’ number of sensors that failed to communicate. Recovered ‘NN’ number of sensors.
- Recommissioning failed: Gateway did not move to the default channel. This is an alarm with the severity of ‘Major’ as this is a serious network condition warning.
Event notifications are shown in the Events tab.
You can configure to receive an email notification for Auto Recovering Lost Sensors. Refer to Configuring Email Notifications.
By default, Manage attempts to recover lost sensors that have not communicated for the past 12 hours. To change the duration or turn off the Automatic recovery of lost sensors feature in Manage, contact Enlighted Support.
