Can anyone identify this chip:
It’s from a LEDVance smart LED tube light, more precisely “SMARTWF LEDTUBE T8EM 1200 18W 865TWLEDV” from here:
I’m trying to figure out if there is any hope of flashing it. Out-of-the-box it’s controlled by a custom app from LEDvance, but the Tuya integration of HomeAssistant detects it.
You would have to pull of the 2D barcode and also the yellow tape to see the circuit and actual chip.
After cutting open the tube and removing the sticker it was easy to identify the chip: BK7231N
It seems there is open source firmware for it! https://openbekeniot.github.io/webapp/devicesList.html
I’ll try to flash, but I’m not sure I’ll be comfortable using since opening the tube damaged it pretty badly…
If anyone knows about a similar smart LED tube that comes preflashed or for which there is a flashing guide please let me know!
You can use cloudcutter to flash it ota
Flashing instruction is a little outdated but should give you a better picture on how it generally works
Thanks for sharing the teardown, i was just looking into those tube led
How damaged is the casing after you did the teardown? Can you provide more pics
