unified-red-test-fork

This module provides a set of nodes in Node-RED to create a customizable building automation user interface or HMI (human-machine interface). Unified-RED is a fork of the popular node-red-dashboard project and adds several features and enhancements:

• Completely rebuilt user security including multi-user support, user roles, user expiration dates, password reset, and more.
• New menu system including unlimited folder levels.
• Date, weekday, and holiday Event Scheduling
• Local or cloud Data Logging as well as an enhanced chart dashboard node to easily plot historical data
• Local or cloud Alarm Logging and alarm console node
• Equipment animated graphics node
• Reusable templated pages aka Multi pages
• New responsive UI rewritten in Angular 9 and Bootstrap 4
• Built-in file manager
• Remote uptime monitor server and API for system integrator monitoring

These nodes require node.js version 8 or newer.

Pre-requisites

Unified-RED requires Node-RED and either MongoDB or SQLite to be installed. Alternatively, MongoDB Atlas can be used for cloud environments. Postgres, MySQL, MariaDB, and Microsoft SQL Server are also supported with the installation of additional database drivers.

Install

To install the stable version:

• Use the Menu - Manage palette option and search for unified-red or run the following command in your Node-RED user directory - typically ~/.node-red:

  npm i unified-red

• Restart your Node-RED instance and you should have UI nodes available in the palette and a new Unified-RED tab in the right side panel.
• Continue to the user interface at http://localhost:1880/ui (if the default settings are used) to complete the initial setup.

Advanced Settings

For a typical installation, the initial setup provides you with everything you need to get Unified-RED setup. However if you need to make a change after initial setup is completed, there are two files that contain all Unified-RED settings:

Node-RED's settings.js File

• Unified-RED URL - The ui.path setting is used (and required) to set Unified-RED's URL to root ("/").
• Node-RED Editor URL - The httpAdminRoot setting is used (and required) to set the Node-RED editor URL to /admin.
• Node-RED Editor Authentication - The adminAuth setting is used (and required) to apply Unified-RED's user authentication to the Node-RED editor. For example, on a Linux machine:

  adminAuth: require("/home/<username>/unified-red/admin-auth"),

  or on the Dialog SmartServer IoT:

  adminAuth: require("/media/sdcard/data/unified-red/admin-auth"),

• Static Web Files - The httpStatic setting is used (and required) to include static files (CSS, JS, image, etc) into the web interface. For example, on a Linux machine:

  httpStatic: "/home/<username>/unified-red/static/",

  or on the Dialog SmartServer IoT:

  httpStatic: "/media/sdcard/data/unified-red/static/",

Unified-RED's config.json File

• dbConnection - URL to the database server instance including the server hostname, port, username, password, and database name, e.g. mongodb://user@password:localhost:27017/unified-red for local instances
• jwtsecret - Unique random encryption key used to secure logins. During initial setup a random key is generated for you, so you typically will never need to change this.
• smtp - SMTP email server information used for system emails such as password resets. Includes server hostname, port, from address, username, password, and optional ssl encryption. If ssl is true the connection will use TLS when connecting to server. If false (the default) then TLS is used if server supports the STARTTLS extension. In most cases set this value to true if you are connecting to port 465. For port 587 or 25 keep it false. For example:

  {
      "fromAddress": "'Unified' <[email protected]>",
      "host": "your-smtp-server.com",
      "port": 587,
      "ssl": false,
      "user": "your-username",
      "password": "your-password"
  }

Layout

The dashboard layout should be considered as a grid using the Bootstrap grid system.

• Page - Each page is made up of 12 columns.

• Group - Each group element can fill any number of columns on a page. The number of columns can vary between small, medium, and large viewing devices. Small usually applies to smart phone users, medium for tablet users, and large for desktop users.

• Tab - All groups are tabbable therefore each group should contain at least 1 tab. If only one tab is used, then the tab header is hidden.

• Widget - Each widget in the group also has a width - by default, 'auto' which means it will fill the width of the group it is in, but you can set it to a fixed number of columns.

The layout algorithm of the dashboard always tries to place items as high and to the left as they can within their container - this applies to how groups are positioned on the page, as well as how widgets are positioned in a group.

Given a group with width 6, if you add six widgets, each with a width of 2, then they will be laid out in two rows - three widgets in each.

If you add two groups of width 6, as long as your browser window is wide enough, they will sit alongside each other.

It is advisable to use multiple groups if possible, rather than one big group, so that the page can dynamically resize on smaller screens.

Features

Dashboard sidebar

The widget layout is managed by a dashboard tab in the sidebar of the Node-RED editor.

Layout:

From here you can build your UI navigational menu, consisting of folders and pages, as well as manage the contents of each page - groups, tabs, and widgets. You can re-order the folders, pages, groups, tabs and widgets using drag-and-drop.

Links to other web pages can also be added to the menu.

Site:

• Site - The name and address of the site (optional)
• Contact - The name and email address of the site's primary contact (optional)
• Monitor Server - URL of the monitor server used to monitor the status/uptime of Unified-RED. Using a monitor server is optional and should only be used by system integrators that actively maintain the site's control system. When used, Unified-RED will heartbeat the monitor server every 24 hours with a unique site ID, version number, and site and contact information.

Files:

From here you can upload, rename, move, delete files, and create new folders in your static web folder. Primarily used to transfer image, CSS, and JavaScript files used to create custom HMI graphics.

Widgets

• Alarm - evaluates an incoming message against a set of configurable conditions. Supports 4 severities - info, warning, alert, and critical.
• Alarm Console - logs alarm messages and notifies web UI. Can be connected to other nodes for messaging, e.g. an email node to send email alerts.
• Animation - used to create animated graphical widgets that are driven by incoming messages.

• Button - triggers a message when clicked. Supports Material icons. Text and background colors are configurable.
• Chart - plots a line chart of historical data.

• Compare - evaluates incoming messages from multiple topics to compute a state. Supports boolean expressions with deadbands.

• Data Log - logs incoming messages into a data logger. Individual topic data log settings can be included in the message, such as max days, units of measurement, enumeration presets, and metadata tags.

• Form - a widget that can be composed of several input form sub-widgets. When submitted all values are sent as individual messages.

• Pager Duty - sends messages to the Pager Duty alerting service.

• Table - displays messages of multiple topics in a tabular format, where each topic is assigned a column or row.

• Template - the template node allows the user to specify and create their own widgets within the framework using HTML, JavaScript, and jQuery. You may also use this to override the built in CSS styles.

• Text - display the value of a message. The layout of the label, and value can be configured.

• Text input - text input box, with optional label. Also supports number, password, email, color picker, and date picker input box types.

Group labels are optional.

Any widget can be disabled by passing in a msg.enabled property set to false;. Note: this doesn't stop the widget receiving messages but does stop inputs being active and does re-style the widget.

Icons

The dashboard has 3 sets of icons built in. They are:

• Angular Material icons: e.g. send
• Material Design Iconfont: e.g. mi-alarm_on - note: add mi- to the icon name in the iconset.

• Font Awesome Free 5.3.1: e.g. fas fa-fire

You can use Material icons in any of the Icon fields. You may also be able to use some icons in labels via their inline style eg <i class="fas fa-flag"></i>

Multi Pages

Multi pages are pseudo-pages used to simplify creating pages with identical groups, tabs, and widgets across multiple building automation devices. In building automation systems, it is very common to use the same HMI graphic across multiple devices of the same type, e.g. VAV controllers. Instead of building an individual page for each device, simply make the page Multi and provide it with instance information to map incoming messages to their corresponding widgets.

A Multi page requires:

• Instance Name Expression - must include {x}.
• Instances - the lists of instance names and parameters must match in length, where names refer to the displayed name or perhaps equipment tag and parameters refers to a set parameters included in the message topic, such as a device ID, device address, or array index.
