The wireless switch can be used for monitoring doors and windows. This option does not include the Door/Window switch and can be connected to your existing door/window reed sensor style sensors. It is small (1” x 1” or 2.54cm x 2.54cm) and can be installed discretely. Battery life is around 1 year depending on number of transmissions. Rugged but elegant cream plastic plastic case allows the sensor to be deployed both indoors and outdoors and if sealed with silicone could be water resistant. Using an external power source it can operate in request/reply or publish mode. When asleep it is awoken by a change in the external switch (i.e. open or close) to send readings. If powered externally then the device can operate in a fully awake mode and can respond to requests for switch state in a request/reply fashion. The device will also transmit switch state changes when in fully awake mode.
