1.6 Troubleshooting
1.6.1 Known Issues
• Sentinare 2 voice call quality: The quality of voice call of Sentinare 2 is still not good enough. We are
working on a solution for this problem.
• LED flashing white: For Sentinare 2, if the WiFi strength is very weak, the device’s LED might turn to
flashing white after failing to reconnect to Wifi. To resolve this issue, please make sure that Wifi
signal is strong enough, and power cycle the device. It will reconnect to Wifi again and come back
online.
• Firmware upgrading cannot start: The firmware upgrade of Sentinare sensor usually needs about
five minutes. If after clicking the upgrade firmware command in the App, the status of the sensor in
the App quickly change from upgrading to the normal status, and the firmware version is still the
previous version, please first try again and make sure it is not due to network glitch. If after a few
attempts, the upgrade still cannot start, please restart the sensor. Sometimes factory reset is
needed (se Sec. 4.2.17) before upgrading again.
• Firmware upgrading got stuck: Sometimes when upgrading the firmware, the sensor could be stuck
and keeps flashing blue light for a very long time (more than 10 minutes). In this case, it is safe to
unplug the power of the sensor and re-plug. If the download was complete, the sensor will upgrade
to the new version after restarting. Otherwise the download will continue automatically and the
sensor will still flash blue. Multiple unplugs might be needed for the sensor to complete the
upgrading. If it still keeps flashing blue after several unplugs, please perform a factory reset from the
App or manually perform the factory reset (see Sec. 4.2.17) before upgrading again.
