  KC868-A8 and PCF8574 Interrupt pin
Posted by: andhol - 05-31-2022, 07:53 PM - Forum: KC868-A8 - Replies (14)

Hi!
I am planning to use all 8 digital inputs of the KC868-A8, and it would be nice to be able to use the interrupt pin of the PCF8574 to detect changes. I'm just not sure if the pin is connected or not. When looking at the schematic, it looks like it is connected to GPIO16, but there is also a red X symbol next to it that might suggest otherwise.. Any hints?

  KC868 A4 - Help In Program
Posted by: mfjunior96 - 05-29-2022, 09:52 PM - Forum: KC868-A4 - Replies (3)

Good night sir,

I'm having a problem and I wanted some help, I have a KC868 A4, I'm using the 4 outputs and 3 digital inputs, but now I want a device (led drivers) connected to alexa to change its state, when I change the state of the digital input , I created a new device "F6" but I can't make "When F6 on > Led Driver ON" the alexa app doesn't let me put a lamp with imput, what can I do? Is there another app that I can do this interaction?

Thanks in Advance
