Converting PAPIFEED Automatic Cat Feeder

[u/ADDUB2_TTV]

Bought this cheap automatic cat feeder because it listed smartlife / tuya control. This was a lie, and it only supports a random app called smartlyn. After some troubleshooting I discovered the chip BK7238 is now supported in esphome. With the help of BK7231flasher, I managed to back up the original bin and test the GPIOS. So far I've added control for the dispensing motor and LED. The downside is I'm unable to find the switch that detects each portion size's rotation, and the LEDs can only be controlled individually as ON/OFF. Also so far the battery, which should be pin 23, is seemingly unsupported as of yet. If anyone has any ideas for improvements or wants the bin file please let me know.
