node-yeelight-wifi

"node-yeelight-wifi" is a node.js lib for controlling via wifi connected Yeelights.

It works with the RGBW bulbs, white bulbs and ceiling lights.

You need to activate "Lan control" on your lights. (see Troubleshooting)

Installation

npm install --save node-yeelight-wifi

Howto

Yeelight Lookup

You can lookup for yeelights in your local network like this:

const Lookup = require("node-yeelight-wifi").Lookup;

let look = new Lookup();

look.on("detected",(light) =>
{
    console.log("new yeelight detected: id="+light.id + " name="+light.name);
});

Methods

Once you have a Yeelight (light) object from a lookup you can use it like this:

setPower(power,duration)

Set the power of your Yeelight (on: true, off: false)

light.setPower(true).then(() =>
{
    console.log("success");
}).catch((error =>
{
    console.log("failed",error);
}));

setRGB(rgb,duration)

Set the RGB value (r: 0-255, g: 0-255, b: 0-255)

light.setRGB([255,255,0]).then(() =>
{
    console.log("success");
}).catch((error =>
{
    console.log("failed",error);
}));

setHSV(hsv,duration)

Set the HSV value (hue: 0-359, sat: 0-100, value/bright=0-100)

light.setHSV([180,70,100]).then(() =>
{
    console.log("success");
}).catch((error =>
{
    console.log("failed",error);
}));

setCT(hsv,duration)

Set the color temp value (1700 ~ 6500)

light.setCT(5000).then(() =>
{
    console.log("success");
}).catch((error =>
{
    console.log("failed",error);
}));

setBright(brightness,duration)

Set the color brightness (0-100)

light.setBright(80).then(() =>
{
    console.log("success");
}).catch((error =>
{
    console.log("failed",error);
}));

updateState()

If you want to request a state (color,bright,power) update

light.updateState().then(() =>
{
    console.log("success");
    console.log(light.rgb);
}).catch((error =>
{
    console.log("failed",error);
}));

Usable (public) Members of Yeelight-Class (read only)

• light.power (true/false)
• light.type ("unknown","white","color")
• light.bright (0-100)
• light.rgb (example: {r: 0, g: 0, b: 0})
• light.hsb (example: {h: 0, s: 0, b: 0})

Events

A Yeelight instance has some events:

//socket connect and disconnect events
light.on("connected",() =>{ console.log("connected"); });
light.on("disconnected",() => { console.log("disconnected"); });

//if the color or power state has changed
light.on("stateUpdate",(light) => { console.log(light.rgb); });

//if something went wrong
light.on("failed",(error) => { console.log(error); });

Troubleshooting

• Yeelight is not detected?
  • enable "LAN Control" on your yeelight
