RE: KC868-A32 configure for ESPhome - nwells - 03-03-2023

I'm having trouble connecting up remote transmitters as they won't accept the pcf8574 settings:
Code:
remote_transmitter:
  - id: master
    pin:
      pcf8574: pcf8574_hub_in_3
      number: 5
      mode: INPUT
      inverted: true
    carrier_duty_percent: 50%

climate:
  - platform: fujitsu_general
    transmitter_id: master
    name: "Master Bedroom - Air Conditioner"
    visual:
      min_temperature: 18

Also, I have multiple binary gpio setup but none of them are triggering. I can confirm they all work as I've setup them up previously on a smaller ESP32 supported board and I'm in the process of upgrading to the large A32 relay board.

Code:
binary_sensor:
  - platform: gpio
    name: "PIR - Front Door"
    device_class: motion
    filters:
      - delayed_off: 30s
    pin:
      pcf8574: pcf8574_hub_in_4

      mode: INPUT
      inverted: true


RE: KC868-A32 configure for ESPhome - admin - 03-03-2023

check your A32 board PCF8574 IIC address value whether correct. after download firmware by ESPHome, see the LOG output, it will show the IIC scan address result.

What about the remote transmitters? This is the compile error I get:
Code:
rc/main.cpp: In function 'void setup()':
src/main.cpp:377:85: error: no matching function for call to 'esphome::remote_transmitter::RemoteTransmitterComponent::RemoteTransmitterComponent(esphome::pcf8574::PCF8574GPIOPin*&)'
   master = new remote_transmitter::RemoteTransmitterComponent(pcf8574_pcf8574gpiopin);

The compile message appears as soon as I add pcf8574: pcf8574_hub_in_3

RE: KC868-A32 configure for ESPhome - nwells - 03-03-2023

I've updated the firmware but still no progress.

I used the settings above:

    scl: 13
    scan: true

    sda: 4

Any ideas?

KC868-A32 no interface for RF receiver module, how do you use remote transmitters ?

I don't need a receiver. The transmitter is defined in my first post above. It worked fine when I had this on a different board - it just needs to send an output signal which is generated by the climate platform.

Could the GPIO issue be pullup related?

RE: KC868-A32 configure for ESPhome - admin - 03-03-2023

you are using PCF8574 IIC for GPIO work as transmitter. maybe PCF8574 speed not fast enough. you can try to set the PCF8574 frequency high, if also can't work , i think transmitter need use ESP32's GPIO, not PCF8574's.

How do I set the frequency to high?

RE: KC868-A32 configure for ESPhome - admin - 03-03-2023

about I2C bus setting in ESPHome, there ia a "frequency" setting.
