This in-wall Dual Relay Module is a transceiver and is fully compatible with any other Halo Smart IoT device. The mini-size design means the module can easily hide itself in the wall box which is good for decoration.

There is a key application by using this module to switch AC power On and Off and this is the lighting control. The new smart relay calibration technology can reduce the inrush current caused by the load and let the module work perfectly with many kinds of light like incandescent, fluorescent and LED light.
