• a scale which obtains weight data of a subject;
• an input device;
• a display device, the monitoring device being configured to display on the display device weight data obtained by the scale;
• and
• at least one communications unit which wirelessly transmits weight data and messages based on input from the input device to the local base unit and which receives at least messages from the local base unit;
• the monitoring device being configured to display on the display device messages based on input from the input device and messages received by the at least one communications unit from the local base unit;
• the local base unit being configured to (a) receive the weight data and the messages wirelessly from the monitoring device without passing through the communications network, (b) transmit the weight data and the messages received from the monitoring device over the communications network for receipt by the remote computer without the local base unit displaying the weight data and messages received from the monitoring device, (c) receive at least messages over the communications network provided by the remote computer and (d) wirelessly provide at least the messages received over the communications network to the monitoring device without the local base unit displaying the messages received from the remote computer;
• wherein the monitoring device and the local base unit are located on a same side of the communications network such that communications therebetween do not pass thorough the communications network and the local base unit communicates over the communications network with the remote computer, and the local base unit is configured to communicate with the monitoring device and with the remote computer without operation of a user interface.
