Hi,

Been playing with Node-Red for a couple of months, working great so far.

I would like to use [node-govee-led - npm ([npmjs.com](http://npmjs.com))]

[node-govee-led - npm](https://www.npmjs.com/package/node-govee-led) in Node-Red, not sure How to do this any advice.

Try to manually install, but nothing is visible in Node-RED.

thanks

As it is not a node-red node (just an NPM package) you wont see anything in node-red pallete.

If you are using node-red V2+ you can add it as an import on a function node...

then use the code as described in the readme.

Thanks for the info, I have implemented all the steps, as described, so far, it is returning a payload of Object Promise, led is not turning on or off. Not sure how to debug. Will do some more testing.

It wasnt clear from the [readme](https://www.npmjs.com/package/node-govee-led) that `getState` returned a `promise`.

Instead try...

```auto
var Client = new Govee({
	apiKey: "<govee api key>",
	mac: "<MAC address>",
	model: "<device model>"
});

Client.getState()
  .then(state => {
    msg.payload = state;
    node.send(msg);
  })
  .catch(err => node.error(err, msg));

```

Ok, a bit better, getting

function : (error)  
"Error: Request failed with status code 400"

# 400 Bad Request

The HyperText Transfer Protocol (HTTP) **`400 Bad Request`** response status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (for example, malformed request syntax, invalid request message framing, or deceptive request routing).

Are your details correct?

My guess is you have something wrong.

what does this return...?

```auto
const Client = new Govee({
	apiKey: "<govee api key>",
	mac: "",
	model: ""
})

Client.getDevices()
  .then(data => {
    msg.payload = data;
    node.send(msg);
  })
  .catch(err => node.error(err, msg))

```

WOW, it is working, the mac address was wrong, I guess there is more than one mac address, in the app it is not showing up the same one. with your command getdevices, I was able to validate the mac.

thanks a lot.
