Questions about the use of WLED and compatibility with other platforms

Hello,
I am new here and recently found WLED. I have created a wearable led suit. https://www.youtube.com/watch?v=cICmOlxom5I I am in the process of upgrading the amount of lights you see in the video. Currently I have 666 leds on the front and 666 on the back. This does not include my arms and legs. In total I have 1820. I am using WS 2812s in the video. My upgrade includes changing the lights on my front and back to APA 102s. I will have 5376 lights on the front and 5376 light on the back. My arms and legs are not changing. I have been using a Teensy to control the lights using Bluetooth and an app I made using App Inventor.
WLED is very interesting to me because it has a ton of patterns that are already created and I wouldn’t have to search all over or create my own. The wheel is already created. The WLED app is also very appealing. It looks very robust.
My questions:

  • I am wondering how I can run a wearable since WIFI is not available but still benefit from WLED. I would like to use a Teensy 4.1 because it has an SD card, has a powerful processor and can handle the amount of lights I will be using. The Teensy has built in ethernet. Would this make the Teensy compatible with WLED? Teensy® 4.1
  • If I use the Teensy would I be able to use the WLED patterns? Would I be able to use the Android app source code to be able to help me make my own app?
    Thanks for your input.

WLED is for the ESP series processors only, the Teensy won’t work.
For the number of LED’s in your project, I’d suggest an ESP32 based board. You may need 2 in sync to handle ~11,000 LEDs, depending on what types of effects you’re driving.
You can operate without a WiFi connection as the standard install will default to its own AP hotspot if no WiFi connection made so you can connect your phone to that for control.

The main limitation to the number of LEDs is the memory available.

Another poster on this forum pointed me to some addressable fairy lights. I have not tried them but they look a lot more flexible than LED strips.

You don’t need WiFi after WLED is set up. In the configuration you set the preset that you want the device to use on boot.

Thanks for the response.
