HomeyScript that checks if the Philips Hue app has a working Hue Bridge connection

is-hue-app-ready.js

// Hue App Status Checker
const HUE_APP_ID = 'nl.philips.hue';

const app = await Homey.apps.getApp({ id: HUE_APP_ID });
const isAppReady = !!app.ready;
if (!isAppReady) {
  console.log('App is not ready');
  return false;

// Grab every device that belongs to the Philips-Hue app
const allDevices  = Object.values(await Homey.devices.getDevices());
const hueDevices  = allDevices.filter(d => d.driverId?.startsWith(`homey:app:${HUE_APP_ID}`));
console.log(`Found ${hueDevices.length} hue devices`)

// If you don’t own any Hue devices we treat that as “not connected”
if (hueDevices.length === 0) {
  console.log('We do not own any hue devices')
  return false;
}

// A single unavailable device is enough to signal the bridge is lost
return hueDevices.every(d => d.available);
