ZigBee Clusters and Ikea Symfonisk Volume Control

[DubbyMcDubs]

Hi,

I have been trying to get the Ikea Tradfri Symfonisk device to report its events via Observe in this library. The device is connected sucessfully and I can ask the gateway for its details and it even send random updates using Observe, however it will not report click and rotation events.

A clue as to why may be in the following comment within the deconz project. The developer says:

"bind the client OnOff cluster to a group. And then the client Level Control cluster. After that, it now behaves normally, waking up to send commands on click and turn. " (https://github.com/dresden-elektronik/deconz-rest-plugin/issues/1898#issuecomment-535090364)

Is there the ability to do this in CoAPnet? I would really love to get this device working. So many uses for it.

Cheers!

Hi, I also have a Sonos so may I can debug as well. Please share some prepared code so that I can try it on my own.

But general speaking: It should work 😄

Best regards Christian

Hi,

Thanks for replying. For clarity, I am not trying to control the Sonos, simply I want to get the events from the Symfonisk volume control from Ikea (https://www.ikea.com/au/en/p/symfonisk-sound-remote-white-40370481/)

Here is some rough test code I threw together:

Connecting:

    try
    {
    var LConnectOptions = new CoapClientConnectOptionsBuilder()
        .WithHost(INSERT_IP_ADDRESS_HERE)
        .WithPort(INSERT_PORT_HERE)
        .WithDtlsTransportLayer(o => o.WithPreSharedKey(INSERT_CLIENT_ID_HERE, INSERT_PSK_HERE))
        .Build();

    FCoapClient.ConnectAsync(LConnectOptions, CancellationToken.None).Wait();

    MessageBox.Show("Connection Successful!");
    }
    catch(Exception ex)
    {
    MessageBox.Show(ex.Message);
    }

Once connected:

        class ResponseHandler : ICoapResponseHandler
        {
            public Form1 FForm1;

            Task ICoapResponseHandler.HandleResponseAsync(HandleResponseContext context)
            {
                FForm1.AppendTextBox(Encoding.Default.GetString(context.Response.Payload));

                return Task.CompletedTask;
            }
        }

        public void AppendTextBox(string value)
        {
            if (InvokeRequired)
            {
                this.Invoke(new Action<string>(AppendTextBox), new object[] { value });
                return;
            }
            textBox17.Text += value;
        }

        private void button6_Click(object sender, EventArgs e)
        {
            ResponseHandler LResponseHandler = new ResponseHandler();
            LResponseHandler.FForm1 = this;

            var observeOptions = new CoapObserveOptionsBuilder()
                        .WithPath("15001/" + INSERT_DEVICE_ID_HERE)
                        .WithResponseHandler(LResponseHandler)
                        .Build();

            var observeResponse = FCoapClient.ObserveAsync(observeOptions, CancellationToken.None).Result;
        }

Does this information help? I am guessing that to make it work we need to find the device ID of the gateway and bind the genLevelCtrl or LevelCtrl clusters between the device and gateway?

Sorry but I don't had the time to test it on my own. I hope to have a look at the weekend.

Hi. Any chance you have made any progress on thi? Cheers.

Sorry for the long delay. I do not have this device so I cannot reproduce the issue. But to me is sounds like a regular observation of messages. This feature is indeed supported by the library.

I created a test and subscribed to changes of a Tradfri Bulb and it works. Hope this helps.
