How to make a Sonoff Mini R2 act as smart relay?

In normal operation, I’d like them to remain closed and use the input from the light switches to send commands to the smart bulbs (instead of actually breaking the circuit).

I’d also like to have a default fallback, so that if the relays can’t connect to Home Assistant, they open and close along with the light switch input.

Sounds like “detached mode”

Light switch - change to detached mode when connection to HA is lost

Hi, How can i configure esp32 light switch to work in detached mode when it has connection t home assistant and when it lose the connection to switch into relay control mode?

It’s easy by just doing something like this:

binary_sensor:
  - platform: gpio
    # ...
    on_state:
      then:
        - if:
            condition:
              api.connected:
            then:
              - logger.log: "We are going full detached now because the api is connected"
              - homeassistant.event: esphome.button_pressed # action when api is connected
            else:
              - logger.log: "No api connection - let's solve things locally"
              - light.toggle: younameit

First, does anyone have a GPIO pinout for the Sonoff Mini R2

You find the GPIO used on the right side here
