Portable addressable led strip tester

It sounds very much that the system was not designed to be easily serviced (sadly a common problem)

I'm trying to figure out a way to make such tester, but the main problem I have is how to deliver enough power for the 3 meter long led strip?

The strip shown above seems to be 144 LED/metre and are the addressable type.

If they are 144/m then one site said it was 43.2 W/m which is 8.64A at 5v.

This means a single 3m length uses 25.92 Amps.

Having two strips off the same supply is likely to cause issues when they are on white and full brightness.

You'd also need to verify that there are connectors at various points.

Looking at your picture it seems that there are power and the connection back to the controller.

If you can confirm the number of LEDs per metre and the type (some more sharp photos will help), then we might be able to suggest a controller.

I am suspicious of the power, and curious to know the wiring running back to the controller as I see three wires along with the DC connector.

The Data and earth are okay but the 5v is only likely to start pulling power from other sections, which may make things worse.

Do you have records of the cause each month, or more correctly what has fixed the apparent problem.

If the LED strips aren't being replaced, then it's either connections, controller or the power supplies.

If the strip isn't the issue, then it sounds like you need a portable strip to prove the rest of the system is working before removing the strips from the ceiling.

WS21812 strips should work even if you don't connect the rest of them after that strip.

Cheers

max 1 time each month. The controller and software is also custom made for this setup, so it's not always a problem with the led strip. that's why we need to test it instead of just replacing it.

Also we need to get the profile out of the ceiling to be able to replace the led strip. it would be great if we can test the bars before dismounting them, because it would safe us a lot of time in case the problem is caused by the controller or the software

I don't understand, the strip's controller isn't accessible during your tests? why to take it out the sealing for testing andd no just power on strip and look if it bright ? Maybe you want test strip before installing on building floor? so you can use this https://fr.aliexpress.com/item/LED-Strip-Light-Lamp-H801-WiFi-Controller-Android-Phone-WLAN-Control-Router-New/32814773646.html?spm=a2g0w.search0104.3.49.8KPSH9&ws_ab_test=searchweb0_0,searchweb201602_2_5570020_10152_10065_10151_5490020_10068_5470011_10305_10304_10307_10306_10137_10060_10302_10155_10154_10056_10055_10054_10059_100031_10099_5460020_10338_10339_10103_10102_440_10052_10053_10107_10050_10142_10051_5380020_10326_10084_10083_10080_10082_10081_10177_10110_10111_10112_10113_10114_143_10312_10313_10184_10314_5560020_10078_10079_10073_5550011,searchweb201603_16,ppcSwitch_7&btsid=0659be23-945d-423a-898a-f05320601bc6&algo_expid=fced1c44-e5b3-415d-b86b-7dfa63494ad8-8&algo_pvid=fced1c44-e5b3-415d-b86b-7dfa63494ad8 and ad a batterie pack as power supply.

You can buy low cost commercial controllers for ws2812 or whatever led type you have or make your own...

Do you know what make/model the LED strips are?

How may LED's need testing by the unit?
