EyeDro Energy Monitor (Work in Progress)

Plugins
#1

This is my first draft of a plugin for the Eyedro energy monitor. (it’s also my first plugin, so be kind on any obvious errors I have made) The Eyedro unit has two sensors, one for each electrical phase. When you access the URL of the device’s built-in webserver, you get back a JSON such as this:

{“data”:[[952,13081,8320,1035],[928,13079,4760,577]]}

This is all documented here: https://eyedro.com/eyefi-getdata-api-command-sample-code/

So far, I am missing a few things in my plugin. I want the plugin to create TWO virtual devices, one for each sensor. Then I need to figure out how to parse the data from the JSON array and get the valuse for each sensor.

This is what I have so far:

plugin.Name = "Eyedro";
plugin.OnChangeRequest = onChangeRequest;
plugin.OnConnect = onConnect;
plugin.OnDisconnect = onDisconnect;
plugin.OnPoll = onPoll;
plugin.OnSynchronizeDevices = onSynchronizeDevices;
plugin.PollingInterval = 10000;
plugin.DefaultSettings = {
    "Host": "10.0.0.140", "Port": "8080"
};

var http = new HTTPClient();
var url;



function onChangeRequest(device, attribute, value) {
    switch (attribute) {
        case "Switch":
            device.Switch = value;
            break;
        default:
            break;
    }
}

function onConnect() {
    url = "http://" + plugin.Settings["Host"] +":" + plugin.Settings["Port"] + "/getdata";
    console.log("connected");
}

function onDisconnect() {
    console.log("disconnected");
}

function onPoll() {
    console.log("polling");
	var response = http.get(url);
    
    if (response.status != 200) { //Any response other than 200 indicates a problem with the request
        console.log("Eyedro Plugin ERROR! Status " + response.status + ": " + response.statusText);
        return;
    }
	
	var sensorDevice = plugin.Devices["1"];
    if (sensorDevice != null) {
        var Eyedrodata = response.data.sensor;
		sensorDevice.PowerFactor =
		sensorDevice.Voltage =
		sensorDevice.Amperage =
		sensorDevice.Wattage = 
	}
}

function onSynchronizeDevices() {
    var eyedroSensor = new Device();
    eyedroSensor.Id = "1";
    eyedroSensor.DisplayName = "Eyedro Sensor";
    eyedroSensor.Capabilities = ["CurrentMeasurement","EnergyMeter","PowerMeter","VoltageMeasurement"];
    eyedroSensor.Attributes = ["PowerFactor","Voltage","Amperage","Wattage"];
	eyedroSensor.Icon = "Gauge";
    plugin.Devices[eyedroSensor.Id] = eyedroSensor;
}

Can someone point me in the right direction? Any feedback would be appreciated.

The plugin has been updated to correctly pull in the Eyedro values and assign them to both devices. (Each Eyedro meter is actually two sensors).

plugin.Name = "Eyedro";
plugin.OnChangeRequest = onChangeRequest;
plugin.OnConnect = onConnect;
plugin.OnDisconnect = onDisconnect;
plugin.OnPoll = onPoll;
plugin.OnSynchronizeDevices = onSynchronizeDevices;
plugin.PollingInterval = 10000;
plugin.DefaultSettings = {
    "Host": "10.0.0.140", "Port": "8080"
};

var http = new HTTPClient();
var url;

function onChangeRequest(device, attribute, value) {
    switch (attribute) {
        case "Switch":
            device.Switch = value;
            break;
        default:
            break;
    }
}

function onConnect() {
    url = "http://" + plugin.Settings["Host"] +":" + plugin.Settings["Port"] + "/getdata";
    console.log("Connected to Eyedrop at " + url);
}

function onDisconnect() {
    console.log("Disconnected from Eyedro");
}

function onPoll() {
    console.log("polling");
	var response = http.get(url);
    
    if (response.status != 200) { //Any response other than 200 indicates a problem with the request
        console.log("Eyedro Plugin ERROR! Status " + response.status + ": " + response.statusText);
        return;
    }
	
	var sensorDeviceA = plugin.Devices["1"];
	var sensorDeviceB = plugin.Devices["2"];
    if (sensorDeviceA != null) {
        //var Eyedrodata = response.data.sensor;
		sensorDeviceA.PowerFactor = response.data.data[0][0]/1000
		sensorDeviceA.Voltage = response.data.data[0][1]/100
		sensorDeviceA.Amperage = response.data.data[0][2]/1000
		sensorDeviceA.Wattage = response.data.data[0][3]
		console.log("EyedroA PowerFactor: " + response.data.data[0][0]/1000)
		console.log("EyedroA Voltage: " + response.data.data[0][1]/100)
		console.log("EyedroA Amperage: " + response.data.data[0][2]/1000)
		console.log("EyedroA Wattage: " + response.data.data[0][3])		
	}	
    if (sensorDeviceB != null) {		
		sensorDeviceB.PowerFactor = response.data.data[1][0]/1000
		sensorDeviceB.Voltage = response.data.data[1][1]/100
		sensorDeviceB.Amperage = response.data.data[1][2]/1000
		sensorDeviceB.Wattage = response.data.data[1][3]		
		console.log("EyedroB PowerFactor: " + response.data.data[1][0]/1000)
		console.log("EyedroB Voltage: " + response.data.data[1][1]/100)
		console.log("EyedroB Amperage: " + response.data.data[1][2]/1000)
		console.log("EyedroB Wattage: " + response.data.data[1][3])
	}
}

function onSynchronizeDevices() {
    var eyedroSensor = new Device();
    eyedroSensor.Id = "1";
    eyedroSensor.DisplayName = "Eyedro Port A";
    eyedroSensor.Capabilities = ["CurrentMeasurement","EnergyMeter","PowerMeter","VoltageMeasurement"];
    eyedroSensor.Attributes = ["PowerFactor","Voltage","Amperage","Wattage"];
	eyedroSensor.Icon = "Gauge";
    plugin.Devices[eyedroSensor.Id] = eyedroSensor;
	
	var eyedroSensor = new Device();
    eyedroSensor.Id = "2";
    eyedroSensor.DisplayName = "Eyedro Port B";
    eyedroSensor.Capabilities = ["CurrentMeasurement","EnergyMeter","PowerMeter","VoltageMeasurement"];
    eyedroSensor.Attributes = ["PowerFactor","Voltage","Amperage","Wattage"];
	eyedroSensor.Icon = "Gauge";
    plugin.Devices[eyedroSensor.Id] = eyedroSensor;
	
	
}

Any suggestions on how I can make it more efficient would be appreciated.
