Refoss Smart Plug with Energy Monitoring from Amazon US
RTL8720CF
CSE7759B
I've been trying to get this smart plug with energy monitoring working on OpenBeken. I was successfully able to flash the new firmware after desoldering the chip. The button, relay, and leds all work fine. However, I can't get the CSE7759B working for the life of me.
In the logs it constantly puts out

Additional Captures:
Any help with this would be appreciated. I plan to do a proper teardown once I get this working.
Attatched are pictures of the board
