Great design. Thank you! I ended up putting a ESP-01 at the top, so I does have a option to control the LED, and I ordered a round LED, too. Now I'm even thinking about placing another LED at the bottom, to get some sort of a effect of the bottom part of the smoke from the "fire". I've also played around with a fire effect, but I'm not there, yet. There's ESP-Home on the ESP-01, btw. The LED is with a 5050 chip, so only three wires, and are able to be daisy chained to the next, but still addressable. I'm powering the LED with 5V, and the ESP-01 with 3.3. A USB cable are pulled up to the ESP-01. I had a broken one laying around.
