node-red-contrib-blynk-ws

Blynk library implementation for Node-RED using WebSockets

Node-RED blynk Websockets version

This library supports both SSL (wss://) and non secure (ws://) connection to local server and Blynk cloud server. For local server, wss:// works only if you ve got a certificate installed. For Blynk cloud server, you can use ws://blynk-cloud.com/websockets or with SSL wss://blynk-cloud.com/websockets as the server url.

If you installed Node Red globally use this command to install npm install --global node-red-contrib-blynk-ws

Supported events, commands and widgets

Events: read, write, app (connected/disconected)
Commands: write, bridge, sync (virtual/all), set property
Widgets: emails, notify, LCD, table, zeRGBa, styled button, image gallery

Changelog

See the changelog for all the details of each releases

Node-RED palette

Blynk App Settings

Use Raspberry PI as hardware to access 128 virtual pins or Generic Board for 32.

How to use

See your server url and auth token in configuration node

See information panel on every nodes

Debug

Use the verbose -v flag when starting Node-RED to get more information or use node-red-log and enable log on Configuration Node as needed

Compatibility

This library is retrocompatible and can replace node-red-contrib-blynk-websockets. To do this:

stop node-red
install node-red-contrib-blynk-ws npm install node-red-contrib-blynk-ws
remove node-red-contrib-blynk-websockets npm uninstall node-red-contrib-blynk-websockets
edit your flow file eg: "my-flows.js" search for 'blynk-websockets-' and replace with 'blynk-ws-'
start node-red.
