The Schneider Electric Wiser Home temperature and humidity sensor combines two sensors in one unit, and measures temperature and humidity in the environment where it's installed. When the sensor is connected to the Wiser Hub, it reports temperature and humidity data to the Hub, which enable setting of automated actions for other system devices when temperature or humidity is below/above a configured treshold. These settings are managed in the Wiser Home App. With a neutral white tone, the temperature and humidity sensor blend well into the room environment. The temperature and humidity sensor is battery operated (1 x CR2450 3VDC battery) and require no cabling. Battery lifetime is 5 years at normal usage.. When the battery is low (less than 10 %), the status LED blinks orange once a minute, and a message is sent to the Wiser Hub to enable notification via the Wiser Home App. Mounting is easy with either screws or tape. It can even be placed freely on a desk or other flat surface. Connect it to the Wiser Hub via the eSetup App for electricians, or with the Wiser Home App. Dimensions: 45 x 45 x 17 mm. Operating temperature: -10C to 50C. The Wiser Home App is available for Android 5.1, Apple iOS 10.3 or higher. Communication protocoll is Zigbee 3.0. Wherever you are, the Wiser Home App allows you to control all the connected devices in the house from your smartphone. Wiser Home is also compatible with the latest technologies such as Amazon's Alexa or Google Assistant and with Merten System M and System D connected devices.
