  • Ok, just an update on this - I had a go, and it needed some changes but it works great!

    I tried to document it at­home-assistant-integration, but basically:

    • Update to the latest EspruinoHub
    • Enable the MQTT option in HomeAssistant and point it at 'localhost'
    • All your devices appear!

    On the Bangle, or some other Espruino device you can now do:

    var value = false;
    function update() {
      g.drawString(value?"ON":"OFF", g.getWidth()/2, g.getHeight()/2);
      NRF.setAdvertising({ 0x2A56 : [value]});
    setWatch(function() {
      value = !value;
    }, BTN, {repeat:true});

    When it's not connected to any other device it'll start advertising when running the code above, and pressing BTN1 will change what it advertises from a 0 to a 1 and back. You can then hook onto that with a rule in Home Assistant :)

  • It looks great. What about when the bangle is connected, e.g. with my phone via gadgetbridge? Will the messages only be sent to my phone rather than broadcasted? Thanks.
