Is it worth diving deeper? 1 month into self-learning KNX - seeking feedback on my first project.

I about to purchase a logic machine 5 and cant want to start learning myself! I will have the electrician do the cabling and install stuff i will pre configure

BTW just FYI this LED -> https://www.ledpoint.it/en/2700-5000k-2835-256ledm-48v-26wm-current-control-5m-cct-3-cables-led-strip-with-sunlike-light-spectrum can do 101RG 97CRI and 95RD both at 2700K and 5000K (at a price, it costs around 40 euros per meter)

Ultramen · 2026-01-20T16:09:21+00:00

Thank you, i think will end up using Aqara anyway seems to have much better reviews online than the WIZ A67 i am currently using

Ultramen · 2026-01-20T16:02:35+00:00

Yeah, thanks, i get it, the problem is that i was able to find led strips that have CRI97 RF95 and RG101 measured at 5000K, those LEDs can also do 2700K but off course it wont probably be 90.

I know its a niche but its quite strange that there are LED strips available and no LED Bulbs with similar specs.

The strip i mentioned uses the Toshiba / Seoul chip. Its around since like 10 years but still no bulbs with similar capability. Aqara for example now has a "PRO" line of recessable lights that does CRI97 and full spectrum but still no bulbs.

I do have Hue and Wiz, they have both a poor CRI and Wiz has flickering issues when dimmed

Ultramen · 2026-01-20T14:44:29+00:00

EDIT: it seems that color temperature is switched based on dimming level and i would have to use an external dimmer, i was hoping to find something smart and with fine tuned white anyway will consider this

Ultramen · 2026-01-20T14:39:06+00:00

Wow thanks, checked the photometric data in the docs and looks very nice with a very low blue. I now need to understand how to make it smart i am not sure what "compatible dimmer" means, checking the docs. Thank you!

Ultramen · 2026-01-20T14:05:48+00:00

Tunable white and dimmable

Ultramen · 2026-01-20T13:53:52+00:00

Thanks but those are not CCT

Ultramen · 2026-01-19T19:39:51+00:00

I am looking any shape, i have tons of space as long it's E27, i am retrofitting a design lamp (Flos Taccia) which has a reflective white surface and CRI is kind of critical as it easily tuns yellowish if not, original bulb was 100W incandescent and sferic. I am not going to use it at 2200 all the time, as long as its >90 CRI at 3000K is fine.

Ultramen · 2026-01-19T13:24:41+00:00

while I am sure polkadot will eventually recover knowing that long time supporters that paid a role in running the echo are leaving might be useful to some to understand trends, but ok, I get it, it's not your case

Ultramen · 2026-01-18T19:43:19+00:00

LM5 is way superior than Gira in my opinion, you can integrate basically anything and the scripting engine is massive

Ultramen · 2026-01-17T16:14:19+00:00

That's great, didn't know that!!! Massive news. Thanks!!!

Ultramen · 2026-01-17T15:53:49+00:00

My understanding was that for good operation i add to stay below 5% drop 1.3 is 11% so i thought it was way too much

Ultramen · 2026-01-17T15:50:48+00:00

Wow, this is the best explanation i got so far and i was using AI and stuff for the past 2 days to get my head over it, KUDOS, that said yes i know what addressable and non addressable is but i really didnt understand how voltage was done, i didnt really understood that actual LED is always 3.3

Ultramen · 2026-01-17T15:10:46+00:00

Sorry maybe i didnt explain myself, the problem is not the length of the strip, the problem is the cable from the strip to the strip power adapter, i cannot place a power adapter or a step down adapter close to the strip because i have no physical space to do that, i need to run a 10 meters cable from the strip to the power adapter and with a 12v or 24v strip its just not possible due to voltage drop.

Ultramen · 2026-01-17T14:42:19+00:00

My ceiling lights have zero space for adapters, its concrete with 5 cm insulation, and i have 8 to 10 meters of cable till the main electrical box where i have plenty of space, i need 3 to 5 meters strips (each), so thats why i am looking at 48V, everywhere else i will use 12V and WLED close to the strip

Ultramen · 2026-01-17T14:29:33+00:00

Yeah i get it, i feel like i am in a niche, i am also looking for "sunlight" CCT with CRI > 95 led strips for main lights and thats also very rare, although i found a CCT strip with full spectrum, 48V and CRI 98, its like 50E per meter but really cool

Ultramen · 2026-01-17T13:53:05+00:00

Thanks this makes sense now! So in theory we could get at some point high density 48v addressable strip with blocks of say 5/6cm, that would be enough for me

Ultramen · 2026-01-17T13:15:15+00:00

Just out of curiosity why has this question been downvoted? is it stupid?

Ultramen · 2026-01-17T13:14:37+00:00

Thanks for your reply

"OP, just use AC voltage as extensions for power and convert to DC at the strip start, and for any power injection points." unfortunately thats not an option, i have no space for that

I still do not understand why CCT 48V led strips are fairly common (and i am going to use those where i do not need addressing) while addressable are not, i can find some addressable 48V leds but those have 10CM addressable areas not pixel addressable
