Within the app, you can check which sensors are online or offline, as well as the battery level, and signal strength of each sensor.
This can help you be aware of when a sensor’s battery may need replacing or recharging, and if a sensor may need to be repositioned due to signal issues.
To see this information:
Tap on the hamburger (three-line) icon in the top right corner.
Go to “Devices” on the menu list.
This will now show all of the sensors, and their various statuses - including battery level, and signal strength.
