esphome HLW8012 sensor not working with BK7231N

[honzakutil]

Hello, I was able to upload esphome to BK7231N (board CB2S). Wifi and GPIOs are working, but I am not able to get working the HLW8012 power sensor (https://esphome.io/components/sensor/hlw8012.html). The esphome HLW8012 seems to need pulse_counter_sensor.h, which needs esphome/core/hal.h.

So the question is: Is the pulse_counter_sensor somehow tightly connected with ESP32/ESP2866 hardware or is it supposed to work also with BK7231N?

ESPhome config file follows:

You likely need to invert all 3 pins, that has pretty consistently been the case so far on the Beken platform.

thanks for quick reply, inverting all three pins solved the issue. Power meter is now working correctly.
