Maybe. But it’s hard without actual devices to test with. If you tell me the deviceID, parameters you connect with in the node app of jangxx and the command you use I can look into it. But the risk of breaking stuff for RGBW devices (which most people seem to have) is big, so can’t give garantees. If you have any programming knowledge you could look into my code yourself and perhaps come up with a PR that fixes this.
λ magic-home discover_json
[{“address”:“192.168.2.103”,“id”:“2462AB4A0B25”,“model”:“AK001-ZJ2104”}]
The programming is to complicated for me at this point (trying to learn though)
Anything else you need?
Yes, the command line command you use the control the cold white through jangxx’s app.
Oh. No, I can’t controll the cold white through node either.
You could ask in the repo of jangxx if this is supported and if so how to do it. If I have that information I can add it to my app. If it’s not possible than you are out of luck.
Ok, but what about the other problem? Dim does not work on warm white in the homey app. If the light is on warm white and I try to dim it, it switches to the last set rgb color and dims that, turning of the warm white light.
Sounds like a bug. Dont have time to dive into it atm though. Could you submit an issue on GitHub so I can look at it on a later time.
Of course. Thank you.
Hi,
Is it possible to add this device in your app? Magic Home dreamcolor device. It can be added to the app right now but only on/off works.
Your best bet is to donate a device to the author of this library: https://github.com/jangxx/node-magichome
This is the library I use for the Homey app.
Could you point me to a aliexpress link that has a controller and led strip that works with your app and has individual addressable led’s ?
I am getting confused with all these names and worried i will order and wait for weekd for the wrong thing.
LED strip: https://www.aliexpress.com/item/32995602877.html?spm=a2g0s.9042311.0.0.72034c4dHCaq7K
You need the 5V version which is sold out at this seller. But you should be able to find it elsewhere.

Thanks so much !
v3.0.2 - 202x-xx-xx
- Updated to SDK3 (requires Homey version 5.x).
- Added support for SPI Addressable Controller including an action card to set one of the 300 pre-configured effects.
This version is available in the test channel in the app store. You can only install this if you are running Homey firmware 5.x which is still in experimental phase.

Hi,
Can you help me with pointing out a 5V power adapter which delivers enough amps if I want this strip with 30 Leds a meter for 3 meters?
I thought I would need 3 meters x 9 Watts a meter = 27. Then 27 : 5V = 6A. But I am not sure
9watts per meter for a strip with 30 LEDs per meter seems rather high. Are you sure about this?
To be on the safe side this is the formula I use.
((meters * Watts p.m.) * 1.1) / Volt = Ampere
I know, but if I click on
The link for the ledstrip you pointed out, it says in the specs that 30 Leds use 9W a meter:
Maybe I should ask the seller about this.
So I got an answer from the seller. Hey confirms that 30 Leds on 1 meter needs 2 Amps, so 3 meter needs roughly 6 Amps.
What do you think about this. Seems a lot to me.
“Each individual NeoPixel draws up to 60 milliamps at maximum brightness white (red + green + blue)” (source). With 30 leds per meter, you’ll need to provide 30 * 0.060 = 1.8A, so 2A is close enough.
However, it seems that may be based on old(er) information. I just tested with a NeoPixel strip that has 41 LED’s, and it’s taking about 0.5A at full brightness white, so 12mA per LED.
That was a nice piece to read. Thank you for that. So basically it means that 6A for 3 meters is only necassary when I intend to use all Leds at full brightness.
