I just purchased this from Amazon and mapped out the pins.
Here’s the relevant portion of my esphome config:
# blue led error light
status_led:
pin:
number: GPIO4
inverted: true
switch:
- platform: gpio
name: "Green Led"
pin: GPIO5
inverted: true
- platform: gpio
name: "relay1"
pin: GPIO12
- platform: gpio
name: "relay2"
pin: GPIO14
binary_sensor:
- platform: gpio
pin:
number: GPIO13
mode: INPUT_PULLUP
inverted: True
name: "Button"
Hopefully somebody else can make use of this. FYI, it also worked great with tuya convert and didn’t require any soldering.
