The Wiser wireless build-in relay (Puck) can be used to switch loads on / off and can also be used to set a timer or a time schedule through the Wiser app. The switched loads can be ohmic, inductive or capacitive loads. It is possible to control the puck in your home through the Wiser app if you own the Wiser Gateway. The puck can likewise be controlled through other Wiser devices if the devices are paired through a Zigbee network. You can always control the puck directly on-site through mechanical push-buttons.
