Hi I’ve recently installed the hive starter kit from maplin, it contains a hub which connects to the internet, a door sensor, and a motion sensor for around £65. You install the app to your phone and it alerts you when the door is opened and closed. You can buy separate door sensors and other hive products at other places too like Screwfix. You have to have internet and a phone that is compatible with the hive app.
I also have a cctv camera pointed at the door so when I get an alert I can log in and check what is going on ie is my grandad around or has he actually left the property and gone wandering. Very useful for night time wandering
