RE: How to use tasmota for KC868-A16 via PCF8574 IIC extend GPIO - davidov.aleksandr1985@gmail - 08-19-2025
Hello. I used the tasmota32.factory_pcf8574_mode2.zip firmware for the kc868-a16 board. However, the pcf8574 is not displayed in the configuration. Please help me understand what I am doing wrong.

The firmware was downloaded from a nearby discussion thread and described as the latest version of the firmware with "psf8574" compilation. I had previously attempted to compile my own firmware as described in the discussion, but the result was the same: no psf8574 configuration

Ok, thank you very much. Please also help me configure the dependence of inputs and outputs. Since the outputs are turned on via the web interface, but not when the input is physically closed.

Hello
The official version does not include PCF8574 support. Nor does it include product-specific software elements.
It cannot be updated online; I tried version 10 and version 12. The OTA update does not work. I think many of us would be very grateful if you could publish an image file containing the latest firmware...
