The Z-Wave Smart Meter Sensor is a compact sensor designed to read gas meter values. Its compact size and external wireless transmitter makes it easy to install in any distribution board. The device is battery powered (will last about 1 year) and reports the meter value once in 15 minutes. If there won\'t be a Z-Wave network, the device will store values up to 3 month. This ensures, that the system can even be used in a minimal configuration with a simple Z-Wave USB Stick (Not part of delivery!) connected to a PC.
