Node Red integration with Blynk App and Server through websockets
\ 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
See the changelog for all the details of each releases
Blynk App Settings
Use Raspberry PI as hardware to access 128 virtual pins or Generic Board for 32.
How to use
See information panel on every nodes
Use the verbose
-v flag when starting Node-RED to get more information
node-red-log and enable log on Configuration Node as needed
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.
What is Blynk?
Blynk provides iOS and Android apps to control any hardware over the Internet or directly using Bluetooth. You can easily build graphic interfaces for all your projects by simply dragging and dropping widgets, right on your smartphone. Blynk is the most popular IoT platform used by design studios, makers, educators, and equipment vendors all over the world.

Quickstart: Arduino + Ethernet shield
- Download the Blynk app (App Store, Google Play)
- Get the Auth Token from the app
- Import this library to Arduino IDE. Guide here
- In Arduino IDE, select File -> Examples -> Blynk -> Boards_Ethernet -> Arduino_Ethernet
- Update Auth Token in the sketch and upload it to Arduino
- Connect your Arduino with Ethernet shield to the internet
Please find examples on how to use different types of connections (transports) and how to do make something great with Blynk. You can easily apply any type of board/connection to all examples.
