The Porthole/door sensor detects and reports opening and closing of doors and portholes. Easily installed on any door or portholes, it triggers a signal when parted. This lets you know when a room is entered, if a porthole or a door has been left open, etc. ZigBoat gateway is required. ZigBoat is an innovative ZigBee/Wi-Fi wireless system for monitoring and interacting with your boat either remotely or while on board ensuring safety and peace of mind with no monthly fees or subscription. The ZigBoat consists of a core module (Gateway) and a series of standard and optional sensors that can be added to your specific needs. Thanks to ZigBee and Wi-Fi wireless technologies, which have direct communication with onboard sensors without the need for a cloud, ZigBoat sends real time push notifications when critical events occur. Using the ZigBoat app, you can check boat information that is being monitored by the system. With the optional 3G USB dongle (cod. ZB210), you can receive also SMS notification in case of a critical event occurs.
