To answer on FORM/POST for login

Dim result As String = ""
Dim WEB = New Net.WebClient()

 

Dim LoginData As System.Collections.Specialized.NameValueCollection = New System.Collections.Specialized.NameValueCollection()

LoginData.Add("user[email]", ID)       // depend on the form field title
LoginData.Add("user[password]", PW)    // depend on the form field title

 

Try
   result = Text.Encoding.UTF8.GetString(WEB.UploadValues(URL, "POST", LoginData))
Catch ex As Exception
   result = ""
End Try

It is pretty easy to apply

Dim WEB = New Net.WebClient()

WEB.Headers("Content-Type") = "application/json"
WEB.Headers("Authorization") = "Bearer " & varToken

Try
    result = WEB.UploadString(varURL&, "POST", "")
 Catch ex As Exception
    Return ("")
End Try

Return result

Just add a token into header, and can access URL

There are so many web base devices, and some webserver device do not have a valid certification,

While access HTTPS using Webclient, will get a trouble with Certification if there is no valid one.

When I access Envoy Local Servier using HTTPS, I have expericed it.

First, create a Validation Server Function as below

Public Function ValidateServerCertificate(ByVal sender As Object, ByVal certificate As Object, ByVal chain As Object, ByVal sslPolicyErrors As Net.Security.SslPolicyErrors) As Boolean

        Return True

End Function

And, Connect the validate server as

Net.ServicePointManager.ServerCertificateValidationCallback = New System.Net.Security.RemoteCertificateValidationCallback(AddressOf ValidateServerCertificate)

When call HTTPS using Webclient, Webclient server will call the user defined server code, and can over-ride an error 

You can put the code into MAIN() -0r-  Sub New() once

From Evnvoy FW7, Just can login into Enovy using Bearer Token,

I have made a simple code using VB.NET to

    (1) Retrieve a Token from Enphase Token Website

    (2) Using the Token, access Enovy's Data

Note. Need to add a certification validating code for Envoy, because envoy's certification is not valid.

Note. Ihave added json.vb for JSON file decord and using in the code        

Test Site

http://www.forby.com/solar/?detail=1

I have started to use SQL server for logging data,

Actually, home_monitor software will collect the information from Envoy & Battery remotely,

and upload the data on website by calling solar_data.php

I am using jpgraph (www.jpgraph.net) for the line graphs,

and just GD line drawing for home layout.

solar.inc               configruation related database

solar_db_initial.php      initialize the database, and add the initial data records

solar_data.php          add some data into db, and get solar informations

chart_panel0_inc.php    house layout drawing information has hard-coded, and location of panel will be

                      referenced from dataset in DB,

I have updated from the concept software

1. json configuration

  need 'envoy.json' in executable folder, it is a configuration file

  It includes

      Envoy Location / ID / Passowrd

      FTP Folder for upload 'index.html' and 'panel.png'

      Battery Back (just optional for myself, if needed)

      Home Graphic Layout

      Panel Layout

      Panel Information (Groups, Location, Orientation, Serial Number, etcs)

2. FTP upload for web interface

  need 'template.html' in executable folder, it will be updated to 'index.html'

      It will showing METER readings

      and Micro-inverter information

      and House Layout

it is just concept how can be monitor Envoy IQ

and Generate Web page, and uploading using FTP

I will not publish the code on this website,

It is the last code for public,

I will just developt for myself only.

In fact, I can not keep going this programming, because I didn't got PTO yet.

and, My solar project has stuck by COVID-19.

Simple JSON Parser for Visual Basic in Class

Example

        Dim JSON As New json

        JSON.Text = System.IO.File.ReadAllText("C:\installer.json").Replace(vbCr, "").Replace(vbLf, "")

        Dim p() As String = New String() {"0", "devices", "0"}

        Dim v As json_value = JSON.Value(p, True)

        Console.WriteLine(JSON.Count.ToString

json_type in json_value

     null = 0

     bool, numeric, text  in json_value.VALUE

     array  in json_value.VALUES

' Read all values

Dim v() as json_value = JSON.Value()

' Read specific value

' Path should be list of ID in level, array ID is 0 ~ nn

Dim v1 as json_value = JSON.Value(path() as string)

' Read specific value, ignore case of ID while compare

Dim v1 as json_value = JSON.Value(path() as string, True)

if can not find a data using IDs, it will return nothing.

if found a data, check json_value.type, and handle the data

This is a good article to read who want to make a remote access

Thank to the app developer

Finally, I have made a simple software using Visual Basic (2015) to monitor Envoy Remotly.

I have attached a source code in this article.

Prepare Remote Access Method

(1) Router Port Forward If needed

   * I am using 80 port for this web server, so, I have forward 180 to 80 to Envoy which has connected via WiFi

   * It makes me to connect on Envoy Web interface remotely

(2) I am getting inverter informaiton

http://envoy:xxxxxx@forby.com:180/api/v1/production/inverters

   * xxxxxx = last six digit of sserial number of your envoy

   * forby.com = it is my home router domain, you can use IP address or your own domain

(3) I am getting meter information

http://forby.com:180/production.json

   * forby.com = it is my home router domain, you can use IP address or your own domain

This software is not completed yet, I just upload back-born for testing, now

ToDo :

          * configuration window

          * data logging into DB

          * create static web page for my web server, and upload
