ESPHome - Blitzwolf BW-SHP6 configuration

ESPHome
10

Only just received two SHP7, the double version of this. Won’t have time to poke the serial and stuff for a while, but uploaded some pictures if anyone wanna have a look under the hood before ordering these.


(No idea if ESPHome is possible or not at this time; looking closer the green module does say RL_ESP8285_Z0_V2.0 so I guess its just a matter of mapping pins one day I have the time:)
((or just pull the module, read the silkscreen, then probe the board another day https://ibb.co/album/jR0taa))

Done intitial pin mapping:

wifi module
IO1/TX   IO3/RX
IO5      IO4
IO0      IO2
IO13     IO12
IO14     IO16
IOUT*    GND
VDD

mapping
IO0       switch1 (next to wifi module)
IO13      led1
IO15      relay1
IO2       switch2
IO12      led2
IO16      relay2
IO01/TX   blue led
IO03/RX** SEL HLW8012? pin 8
IO5**     CF1 HLW8012? pin 7
IO4**     CF  HLW8012? pin 6
GND           HLW8012? pin 5
VDD           HLW8012? pin 1

*) no idea if correct, seems unused
**) untested

Hope to get it flashed soon:) Flashed, need to get buttons and power meter chip working.
Button shows up in log once, but doesn’t do anything besides show up in log.

[22:32:30][D][binary_sensor:036]: 'button1': Sending state OFF
[22:32:33][D][binary_sensor:036]: 'button2': Sending state OFF

add mode: INPUT_PULLUP fixes button.
