Common Sensor (MT) Event Log Messages
Navigating the MT Event Log
The MT event log is a powerful tool that offers insight into the physical state of a given sensor. This article will cover how to navigate the event log and definitions of specific entries.
The event log is accessible through the Meraki dashboard. Navigate to Network-wide > Monitor > Event log.
Note: If using a combined network, click the drop-down at the top of the page and select the for environmental option.
Filter Options
-
Sensor: This filter allows users to select individual MT devices to view individual logs
-
Gateway: This filter allows users to select MT’s based on the gateway access point they are connecting to
-
Event Type: This filter allows users select specific events to focus on
-
Event Type Exclude: This filter allows users to remove event types from the list. Useful if trying to remove common event entries to focus on uncommon ones.
Event Types
-
Battery cover: This event reports when a battery cover is attached to a sensor.
-
Button Press: This event indicates the connection button was manually pressed, triggering a connection attempt to a wireless gateway.
- Door Event: This event triggers if a door is opened or closed.
-
Door Flicker: This event is triggered when an MT20 sensor is right around the threshold of open/close state. If you notice this event, you might want to consider placing the magnet a bit closer to the sensor body. Users can also set up Alerts under the General Status Alert Profile for administrator to be alerted of this state.
WARNING: This type of event indicates that the sensor is flipping between states. Due to the constant flicker, it keeps the sensor awake which has a huge impact on battery life of the sensor.
-
Door Tamper: This event triggers if the sensor detects an unexpected magnetic field that exceeds that of the sensor’s expected magnet. Indicates that additional magnetic devices are affecting sensor operation.
NOTE: This event is also triggered when the magnet tab is too close to the sensor. There should be at least 1 mm gap between the sensor and the magnet.
-
Humidity Event: This event triggers if a configured humidity alert profile is exceeded and indicates a humidity abnormality is present.
-
Missed connection: This event triggers when the wireless connection between sensor and gateway is lost temporarily. Recommend ensuring that the wireless environment is stable and a clear connection is available.
-
Insufficient RSSI: Event triggers if the MT RSSI (Received Signal Strength Indicator) falls below the required minimum.
-
Temperature event: This event triggers if a configured temperature alert profile is exceeded and indicates a temperature abnormality is present.
-
USB connections: This event triggers when a USB cable is inserted or removed from an MT.
-
Water Detection: This event triggers if a configured alert profile is exceeded and indicates moisture is present.
-
Water cable connection: The event triggers if a water cable is added or removed from an MT device.
-
Test notification: this event indicates that a test alert was issued by an administrator.
