I see many people asking for configuration.yaml for A16, A6..etc.

Every person is spending time, building their own yaml-file.

Could you just provide a complete template for each board (A16, A6), that combines all switches, binary_sensors, ADCs, DACs, Temperature sensors... in one text block, combines as one device (with yaml anchor) ready to copy into Home Assistant configuration.yaml?

I think it would make the boards more attractive, if there is an easier start for integration.

Does anyone want to share their configuration.yaml?

I’m struggling with a Kincony KC868-A16 board (ESP32-based) integrated with ESPHome in Home Assistant. I can see all the entities (switches and binary sensors) in my HA dashboard, but none of the physical relays or digital inputs are responding.
The Hardware:

Board: Kincony KC868-A16 (V1.5 or similar with 4x PCF8574 IO Expanders).
Power: Externally powered with a stable 12V 2A DC supply.
Checked with Multimeter: PCF8574 chips are correctly powered at 3.3V.

The Problem: When I toggle a switch in Home Assistant, the UI icon turns "ON" for a split second and then immediately reverts to "OFF". This suggests an I2C communication timeout or write failure. No physical "click" is heard from the relays, and LEDs don't light up.
ESPHome Logs: The I2C scan successfully finds all 4 chips at the expected addresses:

Code:
Found device at address 0x21
(Inputs)
Code:
Found device at address 0x22
(Inputs)
Code:
Found device at address 0x24
(Outputs/Relays)
Code:
Found device at address 0x25
(Outputs/Relays)

Log output:

Code:
[C][pcf8574:024]: PCF8574: Is PCF8575: NO, Address: 0x24

However, when I trigger a relay, nothing happens physically.

here some .yaml config examples for my digital sensors and outputs:
