Connection reset

[mAPBhlJ]

I get the error:

(node:3769) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: connect ECONNRESET 192.168.1.16:80

When I try to run:

var Hue = require('philips-hue');
var hue = new Hue();
var sleep = require('sleep');

var hue = new Hue;
hue.bridge = "192.168.1.16";  // from hue.getBridges
hue.username = "myid"; // from hue.auth

for(var i = 1; i<5;i++){
        hue.light(i).on();
        sleep.sleep(2);
}
sleep.sleep(1);
for(var i = 1; i<5;i++){
        hue.light(i).off();
        sleep.sleep(2);
}

As far as I know this should be working? I've obfuscated the username, but it's actually working for the first few commands.

Is it a network issue or an issue with my hue bridge? Even if so, I think the library should have some kind of safeguarding or reconnect retry?

Does it work if you do not use sleep?

I'm sorry to bother you with this, using setInterval it seems to work. Also, sending too many requests about 10+ a sec will cause the Hue to drop the connection (this isn't caused by your library, rather a limitation of Hue).

var Hue = require('philips-hue');
var hue = new Hue();
var sleep = require('sleep');

var hue = new Hue;
hue.bridge = "192.168.1.16";  // from hue.getBridges
hue.username = "z39w3w8bcDNPitCKg1X47g-PjLr7JNOwtv3dnUUy"; // from hue.auth

var current = 1;

const intervalObj = setInterval(() => {
        hue.light(current).off();
        current++;
        if(current>5){current=1;}
        hue.light(current).on();
}, 5000);

However, what if the connection is ever reset? Does the library autoconnect (or is it stateless, as in, every time a new connection is made)?

Okay I've made a testprogram that runs through a set of hue lights And after 3 seconds does a small spam.

var Hue = require('philips-hue');
var hue = new Hue();

hue.bridge = "192.168.1.16";  // from hue.getBridges
hue.username = "key"; // from hue.auth

var current = 1;

const intervalObj = setInterval(() => {
        hue.light(current).off();
        current++;
        if(current>10){current=1;}
        hue.light(current).on();
}, 1000);

setTimeout( ()=>{
        for(var i = 0; i<6; i++){
                hue.light(1).off();
        }
},3000);

I find that it does throw: (node:3905) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: read ECONNRESET

But actually continues gracefully after that. I feel that that the commands in the spam are lost and when the connection is unstable it may not always toggle your lights succesfully.

I could probably fill in the promise reject with a notification to the user or a retry after a timeout, is that the way to go?
