⚠️ IMPORTANT NOTE

This repository is deprecated. Work on the MicroPowerManager is continued in the EnAccess fork of the repo here.

Background:

Up until October 2022, the MicroPowerManager (MPM) was developed by Inensus in the INENSUS repository (referred to as MPMv1 in this document) and published under and Open Source license in this current repository.

The current version of MPM, developed in the EnAccess repository, significantly differs in design and structure from MPMv1. Key differences include:

• The Frontend/UI is now operated as a standalone application.
• Core functionalities such as Provider, Meter, and other plugins are integrated into the MPM application itself, eliminating the need for installation via external repositories like Packagist (https://packagist.org/?query=micropowermanager).
• The new MPM version supports advanced use cases, including Solar Home Systems (SHS), extending its applicability beyond just mini-grid setups.

Which improves the overall user and developer experience with the project.

To benefit from

• Future feature developments
• Additional provider integrations
• Bug and security fixes

It is highly-recommended that you move to the EnAccess version of the MicroPowerManager.

System Requirements

PHP ^8.0

Node ^v14.3

Installation

1. Clone or download the repository.
2. Build the docker containers with docker-compose up.

Installing Dependencies

All dependencies will be automatically installed during the installation step. However, if you require additional dependencies, install them in the laravel container. To install additional PHP dependencies, enter the Docker container named laravel, navigate to mpmanager, and run composer install XXX.

Migrate the Database

• Run docker exec -it laravel /bin/bash to enter the Laravel container.
• Navigate to the mpmanager directory with cd mpmanager.
• Run php artisan migrate --seed to initialize the database. The --seed option will create the default user for login.
• The default login credentials are admin@admin.com and password will be given in the output of the seed command.

phpMyAdmin

The project also includes phpMyAdmin (only in the DEV environment), enabling quick database operations without installing third-party software or writing commands in the terminal.

The default credentials for the database are:

Username: laravel
Password: laravel

Please remember to change these before publishing your project.

Building the Frontend

The project will automatically build the frontend in development mode. If you want to build the project in production mode, change the APP_ENV variable in the .env file.

Essential Configurations

The system has various bound services like Payment Services (Vodacom Tanzania and Airtel Tanzania), Ticketing Service (Trello API), Critical Logging Notification (Slack Channel), WebSocket (Pusher), etc. If you plan to use these services for payments, you need to modify the following files/configurations.

Mobile Payment Configurations - Vodacom

1. Edit the ips array element in services.php, located under app/config/. The ips element contains a list of authorized IP addresses allowed to send transaction data.
2. Modify the following entries in the .env file:

VODACOM_SPID=YOUR-SPID
VODACOM_SPPASSWORD="YOUR-PASSWORD"
VODACOM_REQUEST_URL="ENDPOINT-WHERE-YOU-CONFIRM-THE-TRANSACTION"
VODACOM_BROKER_CRT="LOCATION-OF-.CRT-FILE"
VODACOM_SLL_KEY="LOCATION-OF-.KEY-FILE"
VODACOM_CERTIFICATE_AUTHORITY="LOCATION-OF-.CER-FILE"
VODACOM_SSL_CERT="LOCATION-OF-.PEM-FILE"


### Mobile Payment Configurations - Airtel
As of now, Airtel payment integration is on a separate project due to the absence of experience in setting up VPN tunnels for multiple hosts. The link to the project will be provided upon uploading to GitHub. Modify the api_user, api_password, and ips entries in services.php:

 --> **The project link comes as soon as we uploaded the project to GitHub** <-- 

Change the `api_user`, `api_password`, and `ips` in `services.php`
```php
  'airtel' => [
        'request_url' => env('AIRTEL_REQUEST_URL'),
        'api_user' => 'YOUR-USER',
        'api_password' => 'YOUR-PASSWORD',
        'ips' => [
            'ALLOWED_IPS TO SEND YOU TRANSACTION DATA'
        ],
    ]

Additionally, change the AIRTEL_REQUEST_URL in the .env file:

AIRTEL_REQUEST_URL="AIRTEL-SERVICE-URL"

STS Meter Configuration

The system currently supports only CALIN-STS meters. To communicate with Calin and generate STS Tokens, make the following changes:

1. Provide your key and the endpoint for creating tokens in the .env file:

CALIN_KEY="CALIN-KEY"
CALIN_CLIENT_URL="CALIN-CLIENT-URL"

2. If you have meters sending consumption data to CALIN's server, fill in these variables:

METER_DATA_URL="REMOTE-METER-READING-URL"
METER_DATA_KEY="METER-READING-KEY"
METER_DATA_USER="METER-READING-USER"

Pusher(Web Socket)

Pusher notifies admins when a new ticket is created.

PUSHER_APP_ID="PUSHER-APP-ID"
PUSHER_APP_KEY="PUSHER-KEY"
PUSHER_APP_SECRET="PUSHER-APP-SECRET"
PUSHER_APP_CLUSTER="YOUR-CLUSTER ex. eu"

Slack

Slack serves as the critical logging service, alerting admins about issues such as canceled transactions.

LOG_SLACK_WEBHOOK_URL="SLACK-WEBHOOK-URL"

Installing Customer Registration App (Android)

Refer to the project documentation for details on why a separate Android app is used for customer registration. Follow the provided link to access the Customer Register App Project.

Setup Sms Communication

There are currently two supported SMS-Gateways.

1. Bongo Live Tanzania
2. Inhouse SMS-Gateway Application

Configuration for BongoLive

Important Note: The Bongo API integration on our system is not been maintained since early-2019.

Firstly, you have to uncomment these lines in app/Providers/AppServiceProvider.php. Because the default SMSProvider is the 2nd option above.

 //$this->app->singleton('SmsProvider', function ($app) {
        //   return new \App\Sms\Bongo();
        //});

After that, change the following configuration

 'bongo' => [
            'url' => 'http://www.bongolive.co.tz/api/sendSMS.php',
            'sender' => 'SENDER_NUMBER',
            'username' => 'USER NAME',
            'password' => 'PASSWORD',
            'key' =>'KEY',
        ],

Configuration for SMS-Gateway Application

Advice: Please read the SMS-Gateway documentation before you continue.

To lower the costs of the system we are using the following application to send and receive SMSes over that application. To be able to use the application you need to assign following configuration values in services.php

You are not forced to use our inhouse solution for SMS communication. You can change the SmsProvider easily in app/Providers/AppServiceProvider.php

 $this->app->singleton('SmsProvider', static function ($app) {
            return new AndroidGateway();
        });

'sms' => [

        'android' => [
            'url' => 'https://fcm.googleapis.com/fcm/send',
            'token' => 'FIREBASE_TOKEN',
            'key' => 'PHONE_KEY',
        ],
        'callback' => 'https://mpmanager.local/api/sms/%s/confirm',
    ],

Dont forget to change the callback variable to a globaly reachable domain

Change Predefined SMS Text

To change the predefined SMS texts, please edit app/Sms/SmsTypes.php

Weather Data

The system shows the weather data on the Mini-Grid level. To be able to read out the data from Open Weather Map service you have to register yourself there and get an API-KEY Change the following value in services.php

'weather' => [
        'owm_app_id' => 'api_key',
    ]

Email

To be able to send E-Mails please edit following configuration variables

return [
    'host' => '', //your host to send through
    'smtp_auth' => true, // enable SMTP authentication
    'username' => '',// SMTP username
    'password' => '', //SMTP username
    'smtp_secure' => PHPMailer::ENCRYPTION_STARTTLS,// default is tls
    'port' => '',
    'default_sender' => '',
    'default_message' => 'Please do not reply to this email', // adds a small footer text to your email
];

Deploy for Production

The production mode will automatically install Let's Encrypt SSL certificates. Therefore you need firstly register a domain.

When you have your domain, the first thing to do is editing app.conf and db.conf(if you planning to use phpMyAdmin as well) files under NginxProxy/conf.p.

Afer that, paste chmod +x ./install-production.sh to make the file executable and run it via ./install-production.sh. This will guide you through the installation and finally, it will start the services.

Development

The development environment is served under http://mpmanager.local To reach the site over the given url; enter the following lines to your hosts file.

For Linux/Mac Users

/etc/hosts
127.0.0.1       mpmanager.local
127.0.0.1       db.mpmanager.local

For Windows

c:\windows\system32\drivers\etc\hosts
127.0.0.1       mpmanager.local
127.0.0.1       db.mpmanager.local

Generate API Documentation

To generate the API documentation, jump in the laravel container and type php artisan apidoc:generate in the mpmanager directory. That will create a new docs folder under public folder. The API documentation should be available under http://mpmanager.local/docs/. The whole API documentation will be migrated to third-party tools like Postman or Swagger.
