buen día , ya resolví lo del teclado wiegand, ahora el problema fue que al meter ese codigo como tengo la entrada digital 1 configurada para si la pongo a gnd se activa el rele 2 ahora se activa solo porque pasa eso ? Si antes no pasaba eso envío foto del teclado wiegand conectado y los cables amarillos son el botón simulado de la entrada P0

Buen día hasta el momento me funciona bien la tarjeta estoy emocionado por las ventajas que ofrece , pero me gustaría saber si puede ser compatible con algún teclado wiegand, ví la publicación que tienen con otra tarjeta pero no me funciona , alguna librería para usarla con esta tarjeta y en qué puerto  

GRACIAS

Hello, I am only a beginner and have problems with interrupt.
I have KC868-A8 V1.5 and use PCF8574. 
The program runs OK, but for the security of the project I need to watch that 1 parameter measured with an analog tool,  stops the whole sketch at avery moment when the parameter is to high.
Is it possible with my Kincony?
Can somebody help with the code? 
Which version on the IDE do I need? 

Kind regards

How can I use water flow meter, if the pcf8574 hasn't activates the interrupts, I need doit in C++, I don't have clue

I'm using a KC868-A16 controller with ESPHome and I've encountered an issue with two inputs that occasionally "jump" - turning on and off by themselves.
to input 03 nothing is connected

 I'd appreciate any help in resolving this problem.

Me pueden ayudar con la configuración en el mismo código de Arduino, el cambio de.pines del rs485 y scl ya que tengo otras tarjetas que programo y no quiero estar moviendo ese dato desde la configuración de Arduino ide, gracias

I would like to make a PID control of 2 3-way valves of the HVAC system. The valves have a 0-10V control and are powered by 24VAC.
I saw the example that controls an RGB led, but now ESPHOME has added the "valve" entity. Is it possible to have an example of how to control a 0-10V valve?

Hi there,

I am writing a TCP string driver for our AV system and I have the board going, and the inputs/outputs work, I am getting feedback.

However, if i send commands quickly it seems to be able to easily overwhelm the board and it crashes - it will reset and work again after a short while. 
I'd understand if it was a lot of packets, but I'm literally sending 1 a second and that's enough to crash the board - it should be able to handle this faster than I can click without issues?

I am only sending one string at a time, either all on, all off, or a multi-on which does a bitwise operation on the AV side and sends the correct string.

Can you advise why this is?

Thanks
