Hello Homey Community, I am using the homey-api package (NPM NODE/JS) to create my own dashboard. I am using the Angular IO Framework to load homey-api. I am able to successfully connect to my Homey and access the list of my devices, but I am unable to subscribe to the device.update event as stated in the documentation. I am not encountering any JS errors or otherwise, but a device status update does not trigger any event on my end. ```auto private async init() { try { // Connect to Homey API const homeyApi = await HomeyAPI.createLocalAPI({ address: environment.homey_ip, token: environment.homey_token, debug: null }); console.log('Connected to Homey locally'); // OK HERE // Load devices const devices = await homeyApi.devices.getDevices(); console.log('Loaded devices:', devices); // OK HERE, LIST OF DEVICE IS AVAILABLE // Subscribe to device update events globally homeyApi.devices.on('device.update', (updatedDevice:any) => { console.log('Global device.update event triggered:', updatedDevice); // KO NEVER PASS HERE // Add your update logic here }); console.log('Subscribed to global device update events'); // Subscribe to specific device updates const specificDeviceId = 'b515b4ca-5570-4a9b-bef8-XXX'; const device = await homeyApi.devices.getDevice({ id: specificDeviceId }); if (device) { console.log('Device found:', device); // OK HERE, DEVICE IS AVAILABLE device.on('device.update', (updatedDevice:any) => { console.log('Specific device.update event triggered:', updatedDevice); // KO NEVER PASS HERE // Add your update logic here }); console.log('Subscribed to specific device updates'); } else { console.error('Device not found'); } } catch (error) { console.error('Error initializing Homey API:', error); } } ``` Please find attached my code so that you can better understand my issue. Thank you in advance for your help and response. Best regards, ---

Before you receive these events you need to use [`connect()`](https://athombv.github.io/node-homey-api/HomeyAPIV2.ManagerDevices.html#connect) (which is one of those things that isn’t documented anywhere AFAIK): ```auto await homeyApi.devices.connect(); homeyApi.devices.on('device.update', ...); ``` Also, there is no event `device.update` on `Device` instances, only [`update`](https://athombv.github.io/node-homey-api/HomeyAPIV2.ManagerDevices.Device.html#.event:update). FWIW, these events aren’t triggered on capability changes, only on underlying device changes (for instance when a capability has been added or deleted from the device, or when a device becomes ready). ---

Hello, Thank you very much for your prompt response. It is greatly appreciated, thank you! Is there a way to monitor status changes in this case? A light turns on, my alarm changes status, a door opens… all the changes of state? Thank you in advance, Sébastien ---

There’s an undocumented event `capability` that you can use: ```auto device.on('capability', ({ capabilityId, value }) => { console.log(`Capability "${ capabilityId }" changed to "${ value }"`); }); ``` ---

Thanks so much for your return. I tried this code, but not working ```auto await this.homeyApi.devices.connect(); // Fetch all devices. // Get device const device = await this.homeyApi.devices.getDevice({id: 'b515b4ca-5570-4a9b-bef8-752a48141acb'}); // Test 1 device.on('capability', (event:any) => { console.log('NOT WORKGING'); }) // Test 2 this.homeyApi.devices.on('capability', (device: any) => { // Subscribe to device update events. console.log('NOT WORKGING'); // NOT WORKING DON'T HAVE THIS LOG ON CHANGE STATUS DEVICE. if (this.subscribedDevices.has(device.id)) { // Check if the device is subscribed. this.deviceDataService.updateDevice(device); // Update the device data. } }); this.homeyApi.devices.on('update', (device: any) => { // Subscribe to device update events. console.log('WORKING'); // NOT WORKING DON'T HAVE THIS LOG ON CHANGE STATUS DEVICE. if (this.subscribedDevices.has(device.id)) { // Check if the device is subscribed. this.deviceDataService.updateDevice(device); // Update the device data. } }); ``` Best regards, ---

It’s OK ! Thanks. It’s not possible to event capability for all devices for have all devices updated some times ? ``` // Get device const device = await this.homeyApi.devices.getDevice({id: 'fd0fef76-ef51-44af-b5ad-ee6caffb835e'}); device.makeCapabilityInstance('onoff', (value:any) => { console.log('Device onoff changed to:', value); // OK }); // Test 1 device.on('capability', (event:any) => { console.log(event); // OK }) ``` ---

Apologies, it should be this: ```auto const device = await this.homeyApi.devices.getDevice({id: 'b515b4ca-5570-4a9b-bef8-752a48141acb'}); device.on('capability', (event:any) => { console.log('NOT WORKGING'); }).connect(); ``` ---
