Host is unreachable, report error

Hi there, just wanted to thank you for this library. There is a nodered plugin that uses this library but looks like the creator is not interested in updating to the latest tuyapi. I though it would just be to pass the version in the constructor and change the package version. But didn’t work for me, so at the moment i am using the library by importing tuyapi into the global context which works good for me now. Describe the bug this is not like a bug but more like a question on the underlying net connect method. To use this tuya sockets i have them set up as mqtt switch in homeassistant, and all commanding and state report is done via nodered using mqtt in-out. To mark the devices as available or unavailable i use a 3 min interval ping to each device. To report the current state of the plugs i use a 10 sec interval query this time using the tuyapi module in a function node. I though to take out the ping out of the flow and just rely in tuyapi but seems like when host is unreachable there is no error report. I am correct to assume the net.connect method will not report any errors if the host is down? just will report on connections errors (sudden disconnect, refused, etc), the docs are not very specific on which errors

https://nodejs.org/api/net.html#net_event_connect

This is the code to check the status i use

const TuyAPI = global.get('tuyapi');
devObj = msg.payload

const device = new TuyAPI({
  id: devObj.devId,
  key: devObj.localKey,
  ip: devObj.ip,
  version: 3.3
});

device.connect();

device.on('connected', () => {
    node.status({fill:"green",shape:"dot",text:"connected"});
});

device.on('disconnected', () => {
    node.status({fill:"red",shape:"ring",text:"disconnected"});
});

device.on('error', error => {
  node.log('Error!', error);
});

let stateHasChanged = false;

device.on('data', data => {
    node.log('Data from device:', data);
    data.dps.power = data.dps['19'].toString()
    data.dps.state = data.dps['1']
    data.devObj = devObj
    delete data.dps['19']
    delete data.dps['1']
    node.send([data,null]);
    device.disconnect()

});

setTimeout(() => { device.disconnect(); }, 1000);

node.on('close', function() {
    device.disconnect() // tidy up any async code here - shutdown connections and so on.
});
