  • Security wise, while I love automating everything, I personally would just give them a physical key to the front door. (Or an RFID keyfob system).
    What you’d be achieving is the equivalent of keyless car entry, with the additional downside that your son can’t choose not to open the door if something sketchy happens.
    And instead of entrusting them with a traditional key that they can treat responsibly, you’re just putting something in their backpack that they don’t have to think about.

    If you really want to do it, basically anything in homeassistant that has wireless capability and a state would probably work.
    A zigbee radio, and pretty much any device doing anything would do it.
    When device_name becomes available, activate door opening.




  • I’m curious to hear what people come up with, as I quite fancy one too.

    I would be wary of installing anything that actually touches the water that doesn’t come from an accredited manufacturer, however. As you don’t want Ali-express grade metal in your drinking water.

    Which unfortunately means the options will be either expensive, or building off the back of other equipment currently installed (water meter, etc).
