Node Red integration with Blynk App and Server through websockets
Blynk app integration with Node Red using WebSockets protocol
This works for both local and cloud Blynk servers. For local, wss:// works if you ve got a certificate installed on Blynk cloud server. For Blynk cloud server, you can use ws://blynk-cloud.com:8080/websockets or with SSL wss://blynk-cloud.com:9443/websockets as the server url.
If you installed Node Red globally use this command to install
npm install --global node-red-contrib-blynk-ws
Supports both SSL wss:// and non secure ws:// connection to local server and Blynk cloud server.
Supported events and widgets
- read event
