npm version Npm download GitHub stars GitHub issues License



This library is in beta, it is not stable yet!!

Do not use for production

Node-RED <-> Blynk IoT Platform

This library supports both secure TLS connection to new Blynk IoT Platform cloud server.

For Blynk cloud server, you can use as the server url.

Local server is not yet supported.

Do not work on old Blynk 0.1 legacy platform

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

Supported events, commands and widgets

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


See the changelog for all the details of each releases

This library is not retrocompatible and cannot replace node-red-contrib-blynk-ws.

The new Blynk IoT platform does not allow migration from the old Blynk 0.1 (legacy), so neither does this library.

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.


Blynk Arduino Library

Blynk App: Google Play | App Store

Optionally you can install Blynk Local Server and run everything locally. However, Blynk Cloud is free for anyone who is using Blynk for personal (non-commercial) use.

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.
