Reddit take

Not enough linked mention summaries yet; the source excerpts below are the evidence.

Pros

  • But esp32s are cheap you can set them up with your home wifi for network.
  • WLED with ESP32 gives you lots to start with, plus you can create your own.
  • Nah it’s like $5
  • What do you have against esp32? They are so cheap.
  • LEDs are individually addressable WS2815 (12v) controlled by WLED running on an ESP32.

Cons

  • Like, a ESP32 project?
  • The device is running on an esp32 powered via usb.
  • Hardware route would be to use something like an ESP32 with something like an AHT10 for temp and humidity values.
  • Then I flashed an ESP32 with ESPHome.
  • Only thing you could do is sniff the protocol with a logic analyzer (or obtain the specs) and re-implement it on a ESP32.

I am going to mount the ESP32 inside a project box, with a battery pack powering everything.

I learned a ton along the way, especially about PCB design, CAD, and ESP32 firmware.

I soldered an esp32 to the button on mine and put esphome on it to push the button. It works really well.
