Sensor Probe Is Disconnected or Data Is Not Updating
Check built-in and detachable probe connections when a Sensor stays online but readings stop updating.
Use this guide when the Sensor System App still shows the Sensor online but its monitoring data does not refresh, or when it reports that the probe is disconnected. If the Sensor is offline, use Sensor Offline first.

Troubleshooting steps
- Built-in probe (ST3/ST6/SS1): Do not open or unplug the Sensor. Contact support if it remains online but does not update.
- Detachable probe (ST4/ST5/ST9/ST10/MS1/SW2): Unplug the probe, clean and dry the connector, and reinsert it firmly. Place the Sensor near its Hub and trigger an update. If another same-model Sensor is available, cross-test the probe; do not force a non-detachable probe.
- External non-detachable probe (ST7/ST8/MS2): Do not unplug or open the Sensor. Treat the issue like a built-in probe issue and contact support with the Sensor SN and probe symptoms.
- Contact support: Provide the model and serial number (SN), probe state, deployment environment, the last successful reading time, and completed steps.
