![[ZIGBEE] 20A Zigbee socket with energy metering (Tuya TS011F_plug_3)](https://obrazki.elektroda.pl/1000454900_1749493372_thumb.jpg)
I seem to have found a new revision of the LSC SMART CONNECT ceiling light
The box looked the same as the older revisions, but the internals are quite different looking. But they still feature the CB2S chip.
Disassembly was quite easy, just twist the plastic lamp cap until it can be taken off without any force required.
The flashing process was also easy, as the module pins were easily accessible after removing the plastic cover by cutting away as small strip of it and bending the remaining part away. I also used the CEN pin thats also labeled on the board, so easy to locate if your not as familiar.
I used bk7231flasher to flash the OpenBK7231N firmware.
