(Question) Use with Raspberry Pi 4 and other strips

[SavageKiller13]

Im wondering if this will work with newer Pi models (4/4B) without any issues. Im also wondering if I can use this with LED strips that have the same wire pattern but different model numbers. Lastly, does the controller.ino only need internet access one time? wondering this because of use off the grid some of the time.

1. It should, I don't have one to test but someone else may be able to better answer this question.
2. If they use the same protocol it should be fine, I think WS2811 works without any modifications. We've been able to get a few strip types working with only minor modifications to the arduino sketch but I can't really give a solid answer without knowing your model number.
3. The sketch doesn't need internet at all, it needs wifi however in order to send the data frames. The wifi doesn't need to have internet access but the computer and the Arduino communicate over wifi so that is a requirement at the moment. (There's a PR for serial only which I have been putting off testing since I don't have the equipment up at college to do so).
