My wife (mainly, my role has been system user/devops) wrote a custom angular UI on top of grocy for managing our household stock (basically any product we buy at grocery stores), there are two bluetooth barcode scanners and screens which allow you to quickly checkout a product when consumed. Since she started gardening she's also "abusing" the db with custom fields to track when she's planted vegetables, harvested them, etc...

Also over 70% of the lights / 50% of other devices in our house are smart (zigbee/wifi/ble) and are connected to home assistant (I very much recommend tradfri+xiaomi zigbee+home assistant). By now I'm sure we've spend over 200h on our "smart home/life", we love data :)
