ESPhome: Treatlife Smart Dimmer Plug with 2 Sockets DP12

I purchased the Treatlife Smart Dimmer Plug with 2 sockets to use with the outdoor Christmas lights and decorations, that way I can automate when they turn on and turn off but I didn’t want to connect it to Tuya Cloud and I already have ESPhome and openHAB managing all the smart home tech. At the time there was no information on how to convert this unit or even if it was possible, there was the DP10 that others converted. This unit was purchased December 2024 and has the CB3S module.

The DP12 has two separate outlets that can be individually dimmed unlike other products out there.

I fired up Tuya-CloudCutter and gave it a try with the DP10 profile, and surprise it worked! After a bunch of trial and error and log watching I’ve got both plugs operational and they can be dimmed! Below is the current YAML code I’m using, this is current as of December 5, 2024. As I discover more about this unit I’ll update.
