•If it's a new Transmitter-Sensor, make sure that you've removed the battery tag.

•Make sure the battery is oriented correctly.

•Is the battery flat? Replace the battery.

•Make sure the Transmitter-Sensor is not too far from the Cloud Receiver and that it is not behind an obstruction.

•Make sure the Transmitter-Sensor (and the Cloud Receiver) are oriented vertically.

•Make sure you've added the Transmitter-Sensor to the Notion Lite system. See Add a new Transmitter-Sensor.

•Notion Lite does not save data on its Transmitter-Sensors; the Transmitter-Sensors have no memory capacity.

•Notion Lite does not save data on its Transmitter-Sensors; the Transmitter-Sensors have no memory capacity.

•Data is stored on the Base Unit if the Base has no network connection or if it is running on back-up power.

•The numbers of days' worth of data that can be stored whilst there is no network connection, or if the Base Unit is running on back-up power, will depend on the number of Transmitter-Sensors on the system.

•The Notion Lite Base Unit has 32 Mbit of Flash storage which can hold up to 29 days worth of data, depending on the number of Transmitter-Sensors on the system.

•Notion Lite does not save data on its Transmitter-Sensors; the Transmitter-Sensors have no memory capacity.

•If the base only lost its network and assuming the Base Unit was down for one day and the system had 30 Transmitter-Sensors, a reasonable estimate would be around 2-3 hours.

•If the base is back-up power, the download can take longer. In this case, up to 5-6 hours for the same amount of data would be a reasonable estimate.

Note:  These figures are only approximations; the time taken will change depending on variables such as the particular version of code and the number of Transmitter-Sensors.
