Firmware Release Notes
To update a sensor’s firmware, if available, press the Update Firmware button in the sensor page of the Sentinare app. If updating from a very old version, it may go through multiple updates. Leave the sensor on and connected to a stable WiFi.
Most updates should finish within 10 minutes. If the sensor blinks blue for too long, it is safe to replug the power to restart the sensor, in case the download is stuck. The sensor should resume download and update automatically.
| Date | Early November, 2024 |
| Versions | • Sentinare 2: 2.0.521 • Sentinare 3: 2.0.521 |
| Improvements | • Improved fall detection • Reduced logging |
| New Features | N/A |
| Known Issues | • A power cycle on some routers, as in the case of a temporary power loss, may not allow Sentinare to automatically reconnect to WiFi. In this case, you may need to power cycle the router again, often multiple times. In our test, up to 5 tries may be necessary. • Sometimes, when switching to another WiFi network using the mobile app, Sentinare may reboot and the operation would fail. In this case, please try again after the sensor has booted back up. |
