Steren RGBWW Desk Lamp

Steren RGBWW Desk Lamp

Device Type: light
Electrical Standard: global
Board: bk72xx
Difficulty: Plug-n-flash, 2/5

Smart desk lamp with a sleek design, it has RGB and warm/cold white LEDs. it uses pwm to control each channel. You can flash it, you can use tuya cloud-cutter, or you can swap out the chip.

I attempted to flash the chip multiple times, but my FTDI adapter couldn’t provide enough current for a successful process. In the end, I followed Digiblur’s Tuya Cloudcutter guide, which is referenced in the ESPHome documentation for BK72xx, and that did the trick.
