The “blynk-library” files installed in /usr/local/lib/node_modules/blynk-library assumes SSL connection in a file called blynk.js. I modified it:
307c307,308
this.conn = new bl_node.SslClient(options);
//this.conn = new bl_node.SslClient(options);
this.conn = new bl_node.TcpClient(options);
That’s all.
