correct, to preserve remaining battery life, place the affected sensor in flight mode
until the underlying mesh, network issues can be properly investigated and
addressed.
4.3.4 Gateway troubleshooting
In the first instance, check the gateway status LED indication: for a gateway that is
powered and connected to @ptitude Observer both LEDs should be green. In
addition, the app functionality can be utilised for basic gateway and system
troubleshooting, by observing whether the device is responsive in a scan of the area.
Possible causes for a ‘non-responsive’ or non-functioning gateway include:
• Incorrect or incomplete configuration.
• A defective or damaged gateway.
• Local hard wired or Wi-Fi, network fault.
• Loss of power or internal fuse/circuit failure.
If the gateway is powered and believed functional but is not connecting to @ptitude
Observer, consult also the System connectivity section.
4.3.5 Commissioning troubleshooting
NFC is a higher frequency, very short-range radio system so positioning and
closeness are important. When using an NFC ‘tap’ to toggle the mode of a sensor, be
aware that the ‘sweet spot’ for NFC will be device dependent. To ascertain this for a
particular device, move it around so that different areas of the rear of the phone are
in close proximity to/touching the sensor. It may also be necessary to remove any
external case or cover around the phone.
The sensor antenna is located internally, towards the middle of the ‘flat side’ of the
sensor case. Its approximate location is marked in the figure below:

In a ‘quiet’ environment it may be possible to hear an audible ‘ding’ as a notification
that the NFC tap was registered by the phone.
