How To Create A Basic Plugin

[stumper66]

I've spent hours on this can't figure out how to create a very basic plugin.
I simply want it to display the inside temperature. This will be done by reading a text file on the server. For now I just set it to a random number.

What am I doing wrong? So far to see the value I am setting I have to go into the device, click on features , edit 'TestDevice', click on Status/Graphics then I can see 'value' in there.
I just want it to display the temperature on the devices page, instead I get this:



Here's my code:

        protected override void Initialize()
        {
            // timer is changing the fake temperature to random values every 30 seconds
            timer = new System.Timers.Timer(30000.0);
            timer.Elapsed += Timer_Elapsed;
            random = new Random();
            timer.Start();

            if (HomeSeerSystem.GetRefsByInterface(Id).Count == 0)
            {
                DeviceFactory deviceFactory = DeviceFactory.CreateDevice(Id).WithName("TestDevice");
                // Identification.EApiType
                deviceFactory.AsType(HomeSeer.PluginSdk.Devices.Identification.EDeviceType.Generic, 0);

                EMiscFlag[] flags = new EMiscFlag[] { EMiscFlag.NoLog, EMiscFlag.ShowValues };
                deviceFactory.WithMiscFlags(flags);

                NewDeviceData newDeviceData = deviceFactory.PrepareForHs();

                deviceId = HomeSeerSystem.CreateDevice(newDeviceData);

                WriteLog(ELogType.Debug, "Creating feature");
                FeatureFactory ff = FeatureFactory.CreateFeature(Id, deviceId);
                ff.WithName("Test Feature");
                ff.WithDefaultValue(-1.5);
                ff.WithMiscFlags(flags);
                ff.AsType(EFeatureType.Generic, 0);
                //ff.AddGraphic(new StatusGraphic("", -100, 120));

                PlugExtraData extraData = new PlugExtraData();
                extraData.AddNamed("temperature", -1.0);
                ff.WithExtraData(extraData);

                WriteLog(ELogType.Debug, "Preparing feature for HsDevice");
                NewFeatureData newFeatureData = ff.PrepareForHsDevice(deviceId);

                WriteLog(ELogType.Debug, "Created device with id: " + deviceId);
            }
            else
            {
                deviceId = HomeSeerSystem.GetRefsByInterface(Id)[0];
                WriteLog(ELogType.Debug, "Found existing device, id: " + deviceId);
            }


            WriteLog(ELogType.Info, "Done with initialization");
            Status = PluginStatus.Ok();
        }


        private void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            HsFeature feature = HomeSeerSystem.GetFeatureByRef(deviceId);
            if (feature != null)
            {
                double randomValue = random.Next(5, 100);
                bool result = HomeSeerSystem.UpdateFeatureValueByRef(feature.Ref, randomValue);
                WriteLog(ELogType.Debug, $"setting value to {randomValue}, result: {result}");

                feature.Value = randomValue;
            }
        }​

For something that simple, you might just want a script to run every 'x' minutes and update a virtual device.

Or use the hello world plugin as a startand tweak to suit
