I discovered some items on clearance at Home Depot, a Wyze Outdoor duplex plug and a Defiant smart plug. Did a little research on the modules I found inside and was pleased that both used esp32 microcontrollers. I got both disassembled, soldered up, and got to work flashing ESPHome, The Wyze was went well and is now integrated into my HA. Unfortunately the Defiant smart plug was defiant and when hooked up to do the flash I got a “Download mode disabled, reset with GPIO0 high.” Researching that I found that newer esp32 chips have a “Secure boot” fuse that once set disables future firmware updates from the UART. Not sure yet if there is an OTA exploit like the with BK7321 toya chips, but i’m not hopefull. If anyone knows of something let me know.

I've had some of those and also some of the proprietary Tuya ones. The module has the same footprint so I ordered some ESP32 modules in the same form and used a hot air rework station to swap them. The modules are really cheap so I still come out ahead price-wise.

I think this one is a custom module, it solders into a slot on the main board vertically with pads on both sides of the modules bottom edge.
