Add color node

[xaliander]

First off - thanks a ton for all of your effort! Second, is there a reason you have not added color manipulation as of yet? This would vastly improve the node-red module in my humble opinion. Cheers

Hi,

Your welcome.

The only reason I stopped is that I had all the functionality I needed/wanted at the time. When you say color manipulation you mean changing the hue? Solid color?

I'll see if I can expose the API around that. Give me a couple of weekends.

Regards,

J.

Hi, yes exactly, I would like to control the color of the nanoleaf panel (same color for all) through node-RED. Awesome, that would be great. Thanks again!

[xaliander]

Hi J., just a quick reminder on the hue change ;) Let me know if there is anything that I can do. Cheers

[morrijr]

Added a 'color' node. Payload needs to be something like; {"r":10,"g":100,"b":5} {"red":10,"green":100,"blue":5} or {"h":15,"s":50,"v":40} {"hue":15,"saturation":50,"value":40}

I'll try and find some time to support more 'CSS' styles of defining the colors, but this should do for you to be getting on with :)

Feel free to send me some example flows!

Awesome thanks! Exactly what I was looking for. =)

I noticed something interesting: When passing a 0 for either red green or blue, there is an error. I'll take a look into it,... maybe I'll be able to contribute a little something as well ;)

Have you tried HSV? It might be somewhere in the conversion code, which is in the library I actually depend on to control the nanoleaf. If it is I might have to either send them a bug request or pull the code into my own library.

[xaliander]

Hi @morrijr, as you can see, the problem still persists even when changing to HSV. I marked the debug message after firing in red. The value 0 seems to be causing the issue as everything works fine when using 1 instead.

[morrijr]

I'm trying to switch from using the nanoleaf-aurora-client to calling the device directly since nanoleaf-aurora-client is no longer supported. Since that library also had the HSV -> RGB function in it I was also looking to use something like color-convert. It would allow a far wider range of color conversions too.

No promises as to timeline though. I have somethings I need to investigate for a work problem too.

[xaliander]

OK sounds good - for now I'll make sure not to put any zeros anywhere ;)... Thanks again for your effort!

[morrijr]

Give this one a try.

Lots more ways to specify the color and hopefully no problems with 0! (At least, I didn't in my tests)

[xaliander]

Have you pushed the update to npm or does it automatically occur? So far I'm having trouble finding the 0.0.5 update...

[morrijr]

It's there in npmjs. Don't know how often node-red scans npmjs though...

[xaliander]

Nice, after the update everything works great. I also appreciated the 0.1.0 update! The transition duration will come in handy =) Thank again!

Hi John, long time no see! Thanks again for your wisdom some time back.

After a firmware upgrade I am receiving the following message:

Is there something I might be doing wrong? The payload looks like this:

Cheers Alex

Hi Alex,

This was working with 3.0.8 updating to what my phone says is the latest; 3.1.3.

To see information about your installation there's a Info node you can wire up to an inject and a debug. It should give you (amongst other stuff) something like;

{ name: "Nanoleaf Light Panels XX:XX:XX", serialNo: "XXXXXXX", manufacturer: "Nanoleaf", firmwareVersion: "3.0.8", model: "NL22" }, rhythm: { hardwareVersion: "1.4" firmwareVersion: "2.4.2" }

Can you get me that information? (Please don't post serialNo or name since that has security issues)

In the meantime I'll upgrade and checkout the API see if anything's changed.

J.

PS, better to open a new issue on GitHub when it's not related than appending to a closed issue. Helps other folks search for things :) But don't worry/bother about it for now.

[xaliander]

Here you go =) Makes sense, I just wasn't sure if it's an error or just me...

{ "name":"Nanoleaf Light Panels XX:XX:XX”, "serialNo":”XXXXXXXXXXX”, "manufacturer":"Nanoleaf", "firmwareVersion":"3.1.2", "hardwareVersion":"1.6-2", "model":"NL22", [...] "rhythm":{ "firmwareVersion":"2.4.3", "hardwareVersion":"2.0", } }

[morrijr]

OK, I think I've got it. Basically they've made the API stricter. If you push this payload

{ "brightness": { "value": 100, "duration": 0 }, "hue": { "value": 120 }, "sat": { "value": 20 } }

into an 'advanced' node set to put and /state it'll work. So I'll update the color node to be correct. I'll also expose a duration property and update the documents. Should be in the next couple of days or so.

Regards,

J.

[morrijr]

There should be a fix available now.

Before I update to 3.1.3 - that includes firmware 3.1.3.? Thanks again, Alex

[morrijr]

Hi, mine is saying it's 3.1.3 so it should be good.
