Raspberry Pi 4 cant connect to ws281x LED strip

  • Hello all,

    Really hoping for some help here. I have spent a number of days trying to get some ambient lighting behind my tv set up. I am running HyperHDR v17 on a raspberry pi 4 and trying to connect a light strip. No matter what I do, i get the below error saying that my LED is disabled because the 'Hardware revision is not supported'. Ive read online that this is an issue with pi5 setups, but I think I should be able to get this set up on pi4.


    I have jumper wire connecting to GPIO 18 pin.

    I am somewhat new to the hardware area here and really could use some help.


    Here is the light strip that I am using: https://www.amazon.com/dp/B07LG6J39V?tag=hyperioforum-21&pd_rd_i=B07LG5JG3Z&pd_rd_w=VCWB6&content-id=amzn1.sym.386c274b-4bfe-4421-9052-a1a56db557ab&pf_rd_p=386c274b-4bfe-4421-9052-a1a56db557ab&pf_rd_r=3QQ90TG6ZKHTK6TJD8WS&pd_rd_wg=VwtUL&pd_rd_r=92d0c8f6-ad18-4215-b1ac-cca5bc08e693&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM&th=1

    For HyperHDR you are unfortunately wrong here.

    12V Stripe and 5V Power supply?!

  • Sorry, I assumed this included HyderHDR. Also, I linked the wrong strip, both power supply and strip are 5v.

    I was able to get the LED strip to work last night without the HyperHDR software, I ran some neopixel python scripts on the pi4 and the lights reacted perfectly. So that pinpoints the issue to being something wrong with the HyperHDR installment or version (maybe). I will keep tinkering with it.
