MEROSS MS310R Plug with CSE 7759b Power Meter Chip causes restarts by whatchdog on ESP12-F

[LupoCri]

PROBLEM DESCRIPTION

Hi.

I have replaced the MRE3S chip in one MEROSS MS310R Plug with CSE 7759b Power Meter Chip whit one ESP12-F but i have repeated restarts by whatchdog.

The UART RX are on GPIO4 - D2.

With ESPHome i have same restarts and the log report "Invalid checksum from CSE7766"

Without UART settings (and no power readings) no restarts happen.

Any idea?

Tnx
