LSC smart plug 2578685

LSC smart plug 2578685

Device Type: plug
Electrical Standard: eu
Board: bk72xx

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)
