    Rather than try to do the time calculations I am trying to use the SWButton.js module.
    This seems to work. Have I got it correct?

    var buttonState;
    var slowTimeout; //< After 60s we revert to slow advertising
    var btnData = {};
    var SWBtn = require("https://raw.githubusercontent.c­om/muet/EspruinoDocs/master/modules/SWBu­tton.js");
    // these get created with a puck button press
    var mySWBtn = new SWBtn(function(k){
      if (k === "S"  ) { // single button press
        btnData.btn = "press";
      }
      else if (k === "L" ) { // long button press
        btnData.btn = "long_press";
      }
      else if (k === "SS") { // double short press
        btnData.btn = "double_press";
      } 
      updateBTHome(btnData);
    });
    
    
    function updateBTHome(btnData) {
      buttonState = btnData.btn;
      updateAdvertising(buttonState);
    }
    
    // Update the data we're advertising here
    function updateAdvertising(buttonState) {
      NRF.setAdvertising(require("BTHome").get­Advertisement([
        {
          type : "battery",
          v : E.getBattery()
        },
        {
          type : "temperature",
          v : E.getTemperature()
        },
        {
          type: "button_event",
          v: buttonState
        },
      ]), {
        name : "Sensor",
        interval: (buttonState!="none")?20:2000, // fast when we have a button press, slow otherwise
        });
      /* After 60s, call updateAdvertising again to update battery/temp and to ensure we're advertising slowly */
      if (slowTimeout) clearTimeout(slowTimeout);
      slowTimeout = setTimeout(function() {
        slowTimeout = undefined;
        updateAdvertising("none" /* no button pressed */);
      }, 60000);
    }
    
    // Update advertising now
    updateAdvertising("none");
    // Enable highest power advertising (4 on nRF52, 8 on nRF52840)
    NRF.setTxPower(4);
    

    Seems quite fast

    Thanks

    this works with press and long_press. I can see the events hapenning under BTHome, device (Puck). I had to add var buttonState; at the top.

    will try double_press next.

    Thanks.

    Still available if anyone interested.

    PS In an automation the device action can be single/double/long etc - but other than a single press nothing is recognized. Thanks.

    Coming back to this for a bit. Great to see a BTHome library. Quick and easy device/sensors into HA.
    Works great with your example using a singlebutton press. I can see the event on the Home Assistant log.

    One thing I can't figure out is how to set up long press and double press events. This sends through both a double and a single press when I hit the puck button once

    ...
    function updateAdvertising() {
      NRF.setAdvertising(require("BTHome").get­Advertisement([
        {
          type : "battery",
          v : E.getBattery()
        },
        {
          type : "temperature",
          v : E.getTemperature()
        },
        {
          type: "button_event",
          v: buttonState ? "press" : "none"
        },
        {
          type: "button_event",
          v: buttonState ? "double_press" : "none"
        },
      ]), { name : "Puck" });
    ...
    

    Feeling stupid - Thanks

    Thanks for the offer - but think I'll go the easier route ie stick to the UK.

    Life moves on and different projects take priority... so selling my Bangle2.

    Factory reset with latest firmware as of today. Excellent condition, buttons all work, battery charges - all lovely. In its original box, with original charging cable and an extra charging cable I picked up.

    Asking £45. Will pay for Royal mail 2nd class shipping in the UK.
    Please respond via DM.

    Have enjoyed this one - now onto other adventures in tiny things.

    Getting back to this with all the Home Assistant updates and saw that BTHome now has button events. Works lovely

    var SWBtn = require("https://raw.githubusercontent.c­om/muet/EspruinoDocs/master/modules/SWBu­tton.js");
    var buttonState = 0;
    var btnData = {};
    var idleTimeout;
    if (!Puck.bleAdvert) Puck.bleAdvert = {};
    
    // these get created with a puck button press
    var mySWBtn = new SWBtn(function(k){
      if (k === "S"  ) { // single button press
        buttonState = !buttonState;
        btnData.state = buttonState;
        btnData.btn = 0x01;
        btnData.press = + 0; 
      }
      else if (k === "L" ) { // long button press
        btnData.press = 1; 
        btnData.btn = 0x04;
      }
      else if (k === "SS") { // double short press
        btnData.press = 2; 
        btnData.btn = 0x02;
      }
      updateBTHome(btnData);
    });
    
    function initBTHome() {
