TZ74 Insert two channel switch module

This describes the Z-Wave device TZ74, manufactured by TKB Home with the thing type UID of tkb_tz74_00_000.

The device is in the category of Wall Switch, defining Any device attached to the wall that controls a binary status of something, for ex. a light switch.

The TZ74 supports routing. This allows the device to communicate using other routing enabled devices as intermediate routers. This device is also able to participate in the routing of data between other devices in the mesh network.

Overview

This z-wave in-wall dual relay switch module TZ74 is a transceiver which is a Z-WaveTM enabled device and is fully compatible with any Z-WaveTM enabled network. Mini size design let the module can easily hide itself into the wall box and that will be good for the house decoration. There are many kind of application by using the module to switch AC power On and Off , one main application is the light control. The new smart relay calibration technology can reduce the inrush current caused by the load and let the module work perfectly with many kind of light like incandescent, fluorescent and LED light.
