    I have one PSU ground on the first led
    And a raspberry ground pin 9 to ending of last strip

    I have 4 connections supplying 5v to each strip

    All solders on all corners are connected except for the last to the first obviously

    For example
    Now I turned it on. Everything works fine for a 1min then it freezes half way

    Should I try and "remove" the last working led and the first not working ?
    The broken one might not be receiving but the working one might not be sending ?

    Maybe software problem? Just remove and reinstall hyperion and sent the json file again.

    Maybe some bug in the software.

    I have done that quite a few times always with the same result.
    It always freezes on the same led though I think I'm gonna try and replace it. I saw on another post that someone had a similar issue and although the led sometimes turned on it turned out to be faulty

    After that I have no idea...

    How many ground connections should I have and where?
    Should I have one common ground among devices ?

    yes! would be the best... as i understand you have two psu, one for the leds and one for the rpi... 5v and gnd from the led psu goes to the led stripe, and one wire should go from the led psu to any gnd pin from the rpi...thats enough

    I currently have one ground from pi to the end of the led strip
    And one ground and one 5v from the PSU to beginning of the strip

    Should I have one from the led PSU to the pi?

    Should I also have ground connected on the 5v I put on every led strip?

    Both the pi PSU (Which is a 3.5a 5v supercharger) and led PSU are connected to an outlet that is grounded at wall socket when connected

    Is it possible for a faulty led to sometimes work ?
    And when it doesn't work is it normal that random Leds light with random colors after?
    I will proceed to swap the suspect led tonight

    Greetings,

    I have good news! It is 90% working lol

    So I replaced the suspect led...and a few others ...lol
    I also redid all the led strip wiring (not sure if this made a diference though) ahah

    And now everything is pretty much in order....
    Except for the bottom led strip (wich is where i swaped the most leds)
    (Used spare pieces os strip and am now out of leds to use)
    If it stays on a static/single color for a while its starts flashing white randomly and then freezes....wich forces me to restart

    Any ideas?
    Another bust led?
    Need to swap the entire strip? (no leds at the moment would have to buy more)
    A weak corner solder?
    Or a current issue?

    Again thanks for all the help
    although im not quite there yet im not so bummed out anymore!
