HOME MONITORING - No more worrying about whether you remembered to close the windows and doors when you left home. Relax in the knowledge that you can check the status of all your sensors at any time, and from anywhere, using the WiZ app. HOME AUTOMATION - Enjoy the benefits of home automation by incorporating contact sensors into your existing WiZ setup. For example, mount one on a door and program your lights to automatically switch on or off whenever you open or close it. ALERTS & LIGHT ALARMS - Receive real-time notifications on your smartphone if any of your contact sensors are triggered. For extra peace of mind, link them to your WiZ lights and create light alarms that flash brightly to warn off potential intruders. EASY SETUP - Easily mount the WiZ contact sensor on any of the entry points in your home using the gentle adhesive tape included in the box . The gap between both parts of the sensor can be anywhere up to 20 mm.
