Partly — if you have the required permissions, you can check the device status and its Device Timeline on the device page to understand when it was last seen and what events occurred, but actually restoring connectivity depends on the sensor and its network environment. If the device identifier is registered elsewhere or provisioned by a vendor, some connectivity issues may require contacting support or the vendor named in the device list.
Devices marked 'Offline' indicate no connectivity for over 30 minutes but raise no compliance issues by themselves. You can verify if the sensor is linked correctly, check the assigned Integration, and confirm that the device is registered and linked to an Asset, Area, or System. However, there is no in-app action to force a sensor online; ongoing connectivity problems often stem from the sensor hardware, its network, or provisioning status, which the vendor or support must resolve.
