Feit BPDIM/WIFI/2

Another Costco/Feit device. This template should work with DIM/WIFI, DIM/WIFI/2, and DIM/WIFI/3, if you can flash it.

Please take note that you will likely have to figure out how to reach the pins and do a serial firmware flash if the device is newer than March 2020. The tuya-convert method is non-functional with the most recent Tuya firmware. I have followed the method described in this SmartThings community post to perform a serial flash. It works as expected.

I split these files myself, but the salient points are re-joined here. You will need to include your own WiFi, etc.

Also of note, adjust the min_brightness! In circuits with many bulbs (particularly with LEDs), dimming all the way can result in complete blackness. By setting min_brightness to a higher value, you can determine what the lowest setting will actually be, and still have some light showing. For example, in some of my circuits, I set this to 143 or 150. Leave max_brightness at 1000.

Disabling serial logging should not be a big deal as this device is unlikely to ever be tethered, except when attempting a manual, serial flash. Once accomplished, OTA is the way to go.
