The Nokia sleep is a sleep monitor that you put under the mattress to analyze your sleeping behavior. The device shows your sleep cycle, follows your pulse and detects snoring. You link him to the free Nokia Health Mate app for personalized coaching, which improves your sleeping behavior. In the morning the monitor automatically sends a report of the last night to the application. You set up the Nokia Sleep once, so you do not need to reactivate the device every night. In addition, you use it in combination with other Smart Home equipment, such as lamps or the thermostat.
