A battery powered remote control unit or other ancillary device (2) is shipped in the same packaging as the main product (1) and is subject to similar environmental conditions throughout the supply chain. The remote control unit is fitted with an environmental sensor (20) to detect such conditions during transit, when the main product (1) has no power supply and stores the data (21). When the main product (1) is first powered up and used, the remote control communicates to the product (1) and relays data captured by the handset (2). This data, together with data collected by the main device (1) when in use, using its own sensor (1), is stored (11) to be retrieved subsequently by a reader 42 to identify events that may have caused a fault in the device 1. |
