node-red-contrib-ui-multistate-switch

A Node Red node to show a switch with multiple states in the Node-RED dashboard.

All credits for the CSS go to hotnipi, my partner in crime for this node!

Install

Run the following npm command in your Node-RED user directory (typically ~/.node-red):

npm install node-red-contrib-ui-multistate-switch

Node usage

SEE OUR WIKI FOR EXTRA TUTORIALS!!!!!

This node allows to show a multi-state switch in a few steps:

  1. Specify in the config screen to use the theme colors, or otherwise specify a separate color for each option:

    Config screen

    • The label is the text that will be displayed.
    • The value will be the payload in the input and output messages.
    • The color is the color of the options.
  2. These options will be displayed in the dashboard:

    multi_switch_color_demo

    As soon as a button is clicked, it's value will be send in the msg.payload of the output message.

  3. It is also possible to inject an input message, with the new value in the msg.payload. The corresponding option will automatically be selected in the dashboard.

Node properties

Label

The label is the text which is displayed in front of the switch. Note that the label can contain Mustache syntax, in case the label needs to be changed dynamically via input messages. See this wiki page for more information.

Extra options:

  • Via the "Appearance" option (see below), multi-line labels can be activated:

    Multi-line label

  • When dealing with a long multi-line label, it might be useful to increase the height of this widget:

    Height increased

  • It is also possible to show an icon inside the label. See this wiki page for more information.

Appearance

The appearance determines the shape of the switch button, which allows you to have rounded corners:

Appearance

For advanced users, the following flow contains a Template node with a very simple CSS script to achieve the same result:

[{"id":"11079fb1.5eebe","type":"ui_template","z":"2b6f5d19.202242","group":"9f2da61.3353758","name":"Dashboard CSS","order":2,"width":12,"height":1,"format":"<style>\n    .multistate-switch-wrapper{\n        border-radius:15px;\n    }\n    .multistate-switch-slider{\n        border-radius:15px;\n    }\n</style>","storeOutMessages":true,"fwdInMessages":true,"resendOnRefresh":true,"templateScope":"global","x":460,"y":1960,"wires":[[]]},{"id":"1730cdc0.2bad52","type":"ui_multistate_switch","z":"2b6f5d19.202242","name":"","group":"28a39865.fa3608","order":2,"width":"9","height":0,"label":"Thermostat","options":[{"label":"Option 0","value":"option_0","valueType":"str"},{"label":"Option 1","value":"option_1","valueType":"str"},{"label":"Option 2","value":"option_2","valueType":"str"}],"x":460,"y":1900,"wires":[[]]},{"id":"9f2da61.3353758","type":"ui_group","name":"Flight","tab":"d6d3c358.5fb46","order":1,"disp":true,"width":"12","collapse":false},{"id":"28a39865.fa3608","type":"ui_group","z":"","name":"Default","tab":"d8520920.0128d8","order":1,"disp":true,"width":"9","collapse":false},{"id":"d6d3c358.5fb46","type":"ui_tab","name":"Home","icon":"dashboard","order":1,"disabled":false,"hidden":false},{"id":"d8520920.0128d8","type":"ui_tab","name":"Home","icon":"dashboard","disabled":false,"hidden":false}]

Use theme colors

When activated, the switch will be displayed in the current theme colors. When not activated, it is possible to select a separate custom color for each option.

Theme colors

Hide label of selected option

When activated, the label of the selected option will not be displayed:

Hide label

Passthrough

Specify whether input messages should be passed through as output messages:

  • Never: The input messages will never be passed through as output messages.
  • Always: The input messages will always be passed through as output messages.
  • If state changes: The input messages will only be passed through, when they change the switch state. Which means that messages containing successive duplicate states, won't be send to the output.

Input msg

Specify whether input messages should be accepted:

  • None: The input messages will never be accepted.
  • All: The input messages will always be accepted.

User input

Specify whether user input (i.e. click and touch events) should be accepted:

  • Disabled: The user input will never be accepted.

  • Enabled and show: The user input will be accepted, and the new state will be visualized (i.e. the switch will switch to the new state).

  • Enabled but don't show: The user input will be accepted, but the new state will not be visualized. This could be used if the switch needs to show the real state. As soon as the real state changes, it will be injected into the switch node which will visually switch to the new state. A "ripple" effect has been introduced to visualize that another state has been clicked:

    multistate_ripple

    Note that only the first time that another state has been clicked, an output message will be sent!

Note that the look and feel of the switch will also change when enabled or not:

Disabled switch

Options

Specify the options (label and value) that needs to be displayed inside the switch.

Note that a label can contain an icon. See this wiki page for more information.

State field

Specify which field in the input and output message will contain the new switch state. By default msg.payload will be used.

User input field

Specify which field in the input message will contain a value, indicating whether the switch should be enabled or not. Which means whether it allows user input (click/touch). By default msg.enable will be used.

The content of this message field can be:

  • "enabled_show": see user input modus "Enabled and show" for more information. For legacy reasons, it is also possible to use true as content.
  • "enabled_not_show": see user input modus "Enabled but don't show" for more information.
  • "disabled": see user input modus "Disabled" for more information. For legacy reasons, it is also possible to use false as content.

See example flow in this wiki page.

Passthrough field

Specify which field in the input message will contain a value, indicating whether the input messages should be passed through (to the output) or not. The value can be:

  • "never": see passthrough modus "Never" for more information.
  • "always": see passthrough modus "Allways" for more information.
  • "change": see passthrough modus "If state changes" for more information.

See example flow in this wiki page.

Input msg field

Specify which field in the input message will contain a value, indicating whether the input messages should be accepted or not. The value can be:

  • "none": see input msg modus "None" for more information.
  • "all": see input msg modus "All" for more information.

See example flow in this wiki page.

Topic

Specify the text that needs to be send in the msg.topic field of the output message. If no value is entered, the original topic will remain unchanged (if available in the input message already).

Example flow

The following flow shows switch button with 2, 3 and 4 states:
