I’m trying to keep a clever 5 year old from getting out of the house undetected. Looking for a door alarm/chime that works both dumb (built in alarm) and smart (zigbee preferably for HA). Any suggestions?
This is what reed switches are for and in the case of home automation for a out of box option you can use a door and window sensor on the door(s) then tie in an automation to play the chime on your speakers or phone via notification to let you know when its opened or left opened.
You can even embedd the door sensor into the top of the door and then the magnets to trigger it in the frame where they meet to register the door is in the closed position.
do you currently have a home alarm?
