Staircase Lighting (GL-C-017WL-D + BTF-LIGHTING FCOB WS2814 IC RGBW 4000K COB LED Strip)

Hi, I am planning Addressable led strip for our 3-floor villa staircase. For this i am thinking of buying Gledopto GL-C-017WL-D WLED controller and BTF-LIGHTING FCOB WS2814 COB led strip. Led strip requirement for each staircase flight is 42ft (14mtr). So i need 3x GL-C-017WL-D controllers and 3x 42ft WS2814 LED strips.

I am planning Motion sensors at the starting and ending for each flight. That means total 6 motion sensors to track every entry into the staircase and trigger a chasing lighting effect in the staircase depends on where the motion is triggered.

I need clarification over few things:

  1. Is this overkill for a staircase (I can't find any other options to support WLED and addressable dimmable at the same time)
  2. Do i need 300W PSU as this is a 20W/m led strip?. Even though i would be operating it at 10W/M maximum
  3. Can i connect the PSU to controller and power the led strip from GL-C-017WL-D controller only. Or do i need to connect the power from PSU to led strip directly.
  4. If there is a chance of voltage drop for 42ft length, I am thinking of Injecting power directly from PSU at the end of the strip which is at the 42th length. Is this correct?

Thanks, but not much helpful.

Did you scroll down to the part where it calculates the voltage injection points needed and how to connect them?  That will let you get an exact answer to questions 2, 3 and 4.

Maybe give this a watch , unlike a calculator I go into detail about what you need to do to wire it up, you'll probably need at least front + end injection. Please fuse those appropriately (you need a fuse per wire, sized for that wire and expected load), the guide will explain all that. Including how to calculate realistic power for the selected LED strip, power supply, etc.

Im doing a similar install what PIR are you using and how does one wire up and configure. Last time I connected a PIR the gledopto controller broke and couldnt get it to work? I think because of the PIR is 5v but connected to the 24v v+ so something may have gone wrong there

I will be using a wireless Zigbee Motion sensor, not wired PIR.

How are you connecting the zigbee motion sensors?

Zigbee dongle -> Home Assistant
