In order to keep a close eye on your home, you are going to need a decent security camera. Investing in smart contact and motion sensors can also help. The Onvis Thread-Enabled Door/Window Contact Sensor is designed to work with HomePod Mini and Apple TV. It combines with your phone to let you know when your doors or windows open in your home.
This door sensor uses Bluetooth low energy and lasts up to a year on standby. Since it is designed to work with HomeKit devices, you can use this sensor to automate your lights and other smart devices. You will be able to see past records on the ONVIS Home app.[where to get it] [app]
