8 months ago After further research, I found out that it is more likely to be a websocket related issue which is described here. Websocket-Node No timeout
A fix for LGTV2 might look like this...
In the constructor, pass a user-defined parameter for the connection timeout, e.g. conTimeout
var lgtv2 = require("lgtv2");
var lgtv = new lgtv2({url: `${wsurl}`, keyFile : 'keyFile', reconnect: 5000, wsconfig:{'conTimeout':5000, ... });
...WebSocketClient.js (line 254)
var req = this._req = (this.secure ? https : http).request(requestOptions);
+ req.on('socket', function (socket) {
+ socket.setTimeout(self.config['conTimeout']);
+ socket.on('timeout', function() {
+ req.destroy();
+ });
+ });WebSocketClient.js (line 87) extend the config
+ conTimeout: 5000,Edited: The previous solution did not work! I had to patch the WebSocketClient.js after all :(
If you disconnect the LG TV from the power supply and then switch it on again, there is a small time window during the boot-up sequence where a TCP connection can be established. Approx. 7 seconds. If the LGTV2 client establishes the connection to the LG TV exactly during this time, the client hangs forever and blocks any further processes.
Do you have an idea or a workaround to prevent this?
You can test it by pinging the TV during boot-up. If the server responds, try to establish a connection with your LGTV2 client. Important: Before disconnecting the LG TV from the power supply, switch off the TV with the remote control and wait 10 minutes until the pixel cleaning process has been completed. This process runs in the background after switching off the TV.
