I have run out of GPIOs on my ESP32 and am using a PCF8574 for some additional output and inputs.
I also need to be able to expose some binary_sensors to HA that aren’t associated with inputs or outputs. A bit like an input_boolean in HA.
Is there a way to do this without adding another PCF8574 and then not using the pins?
I guess I’m simply asking if there is an input_boolean equivalent in ESPHome that can be configured and exposed to HA.
Hope that makes sense.
