  • 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).







  • It is indeed! Mostly just fiddling around with the settings.

    @smeg@feddit.uk, here is a paste of the config so you can play with it:
    (If you click show code editor, then paste in, you can then go back to visual editor with things configured)

    Speedtest needle gauges and ping with colour change:

    type: horizontal-stack
    cards:
      - type: gauge
        min: 0
        severity:
          green: 80
          yellow: 50
          red: 0
        entity: sensor.speedtest_download
        max: 100
        needle: true
      - type: gauge
        min: 0
        max: 20
        entity: sensor.speedtest_upload
        severity:
          green: 16
          yellow: 10
          red: 0
        needle: true
      - type: gauge
        min: 0
        entity: sensor.speedtest_ping
        severity:
          green: 0
          yellow: 15
          red: 20
        max: 100
    
    

    Air quality with lots of different colours:

    type: horizontal-stack
    cards:
      - type: gauge
        entity: sensor.oxford_air_quality_index
        needle: false
        min: 0
        max: 500
        segments:
          - from: 0
            color: '#00e400'
          - from: 51
            color: '#ffff00'
          - from: 101
            color: '#ff7e00'
          - from: 151
            color: '#ff0000'
          - from: 201
            color: '#8f3f97'
          - from: 301
            color: '#800000'
        name: 'Air quality: PM2.5'
        unit: µg/m3
      - type: gauge
        entity: sensor.external_environment_f
        max: 40
        severity:
          green: 18
          yellow: 25
          red: 30
        needle: false
        min: -10
      - type: gauge
        entity: sensor.oxford_uv_index
        max: 10
        severity:
          green: 0
          yellow: 3
          red: 6
    

    Once you’ve got your head around horizontal stacks (lets you put multiple small dials together), it’s mostly picking thresholds and settings colours.


  • Currently, it’s using a Waze integration.
    The coolest thing, is that it’s given me a really nice data set for when are the bad times to drive across town are. (Sadly, it’s during the morning and afternoon school runs).
    It also reveals that the travel time on average is impacted significantly by the school holidays, and the weather.
