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.
What is Blynk?
