![[ZIGBEE] 20A Zigbee socket with energy metering (Tuya TS011F_plug_3)](https://obrazki.elektroda.pl/1000454900_1749493372_thumb.jpg)
I want to tell about the gadget "Cob Led Strip 3000K to 6500K SSDNWFB1R4" from the vendor "Gliztech" that I bought recently and flashed successfully with Openbeken. The user manual calls it "SWIFI-W-COB-202406". It's a LF686-Chip on a board named "ZJ-BWCD-CCT-VC-IR V1.1".
First I tried to flash it via Wifi OTA, but it gave several errors: ok=up_ErrHttp, up_ErrCheckR or up_ErrHEADER. I write down how I have done it anyway, perhaps someone else finds out how to succeed:
On the first terminal I wrote:
and on the second:
Please be aware of the http-version "HTTP/1.1" because otherwise it only gave http-Errors. Similarly the name of the file had to end with ZG-BL.
Eventually, since flashing via Wifi didn't work, I soldered the pins and flashed it with blflash.
Here you'll find my settings:
