Has anyone had a play with individually addressable LED Strip (5050SMD/W2812B chips)?
Can you share your set-up/drivers?

I know you can do it via arduino etc but is there an off the shelf 'driver' that can easily be integrated?
Even just on/off in a scene within loxone then it runs a preprogrammed cycle. I'm thinking just a party-mode event.

Actually yes, I just installed a 5m strip on my deck. I’m using the LeDMXPro from DMXking to control my house lights (1 DMX universe w/ 2 x 32 channel PWM drivers), but since this device has 4 additional outputs for addressable LED strips I couldn’t pass up the opportunity. I found some 24v strips (rare — in hindsight I should have gone 5v and added another buck converter to convert from my system’s native 24v). I can’t remember the details, and it doesn’t matter too much as this driver handles a very long list of chips. If I remember correctly I’ve got 12 LEDs/meter for 60 total on a strip. Just one strip so far, but I’ll probably mount another once I get this one working properly. The strip works great, but I need something to send ArtNet (DMX Ethernet, basically) to the LeDMXPro. I can do that from my iPad (there are many apps, most of them surprisingly crappy), but I’m going to enhance my home automation software to do so directly. I plan is to normally just have on/off, dimming, and RGB control through the Loxone UI plus my usual 2-button wall switch interface... I may do something fancier in the future but for now I’ll just have it be one colour, perhaps with something a bit interesting during fade up/down.

it might be quicker and easier to get the pixel function to work, rather than as a single colour led strip, by using a hardware controller with an api that can be triggered from loxone to change the patterns

there are plenty around, many running on single board processors such as the rpi,  most not commercial, for example:

How many dmx channels would you need from the Loxone dmx extension if you were looking to integrate a LED strip driver with different scenes.

Each individually controllable “pixel” needs 3 (RGB) or 4 (RGBW) channels in the DMX Universe. My strips are 50 pixels RGB, hence 150 channels. I put these in each of their own universes. Needless to say I’m not using the Loxone extension anymore.

The requirements quickly escalate if I were to use something like the lumilum system as it appears they are at a pixel density of like 20 per foot.

That’s where something like this becomes very handy:  http://dmxking.com/artnetsacn/edmx4-pro-din

The quick answer: too many.

IMHO Loxone is not designed to handle IA strips or arrays and programming these in Loxone would be a nightmare.

If it were me (and I did look at this) I'd use a RPi to drive the IA Leds and have Loxone tell it what animation/sequence/pattern/colour/etc. to display (very easily via HTTP virtual output).

Thanks for the advice. I came to pretty much the same conclusion and for my use case it was going to be a nice to have anyway. I'm currently thinking I'll put in some 24V strips and locate a dmx decoder/driver near the install. Something like this https://www.aspectled.com/products/4-channel-rgbw-dmx512-decoder-and-led-driver?gclid=CjwKCAjw1KLkBRBZEiwARzyE73OkyoOrDAnBW9SG9QbY-5MLYbKs8QadEGukHv7zvai0vyAjhos-9hoC7CsQAvD_BwE#tab-1

Interesting this came up since I was looking at this - it is a pretty active community of people who do this - for Christmas lights. Here is a post to get started:


Basically a Raspberry Pi runs it.
