I recently flashed a chip (which reports as rtl8710C). I have it in a gosund SP112 with cuco z0 r v1.2 I flashed ESPhome using ltchiptool. After figuring all pin assignments, I found that there is no reading from BL0937. The Button, LEDs, relays are working. I measured the pins sel, cf and cf1 with an DSO and saw the signals are there. And also verified the traces to the pins at the board. I can even see the sel pin swapping high/low (controled by ESPhome firmware). I can just guess that it might be an issue with PWM inputs but I dont know how the hlw8012 platform treats the inputs. In ESPhome I used the board: "generic-rtl8720cf-2mb-992k". Hope one can give a hint.
