LSC smart plug 2578685

bk72xx eu Comes with ESPHome plug

LSC smart plug 2578685 - lsc-plug-no-box2578685.jpg

Warning

The latest LSC smart plug 2578685 devices use the Tuya BK7231N module, which is not compatible with ESPHome!

Notice

This smart plug is flashable using the latest tuya-cloudcutter with a compiled ESPHome binary. I recommend following this Youtube Video.
There is a version with BK7231N and a version with BK7231T. Both should work but you need to make sure to use the right version. I recommend to use the the configuration gererated by ltchiptool and esphome-kickstart as shown in the video instead of this configuration, because it might change.
The second configuration is the version that worked for me (Version 1.1.8 in the App and with BK7231N)
