improvement:

add "MOTT feedback all channels" option in webpage setting. Support home bridge.

Enable= MQTT message will feedback all channels state
Disable= MQTT message will feedback single channel

   
   

Can anybody help me with information relating to the ESP32 GPIO pin used to connect the IRQ (nINT) from the PCF8574 (Digital inputs 1 to 6).

I need to be able to capture very irregular (maybe 10 per minute) but short pulses (< 10mS duration) pulses without missing any.

I would hate to have to schedule I2C reads every 5mS or less to make sure nothing is missed.

I have had a look at the KC868-A4 schematic and the DI1-DI4 pins are directly GPIO connect, not through a PCF8574 GPIO extender.

Hi
It's possible to use the bluetooth of the A8 ;
How to have access to bluetooth (esphome, tasmota, KCS); 

Thank you.

I am building a house, tell me what is better to use for a smart home:
16 group curtains and roller shutters (I have an RR06 receiver under the roller shutter and I need to connect it to a low current switch and see them in the home assistant) ).
I want to manage underfloor heating, I have 2 floors and warm floors everywhere, it is desirable to manage separately separately.
I will also have RGB in my room and the lighting will also control it (about 5 rooms with RGB), and around the house there will also be ice in the caecum, but an ordinary tape, 300 meters of tape in a circle.
There is also a snow melting system in a circle (ProfiTherm D-4, D-3, ProfiTherm Eko Plus), the shower would be controlled. Lighting will also be about 50 groups.
Cameras in a circle (I want to implement the structure of faces)
Also interested in IC management.
I have a rassbury pi 4 8gb.

this is a demo , i have created one switch button in ESPHome, you can create many others.

KinCony Products use modbus command:
01 05 00 00 FF 00  turn on relay1
01 05 00 00 00 00  turn off relay1

make sure your relay board as these:
ON = 0xFF00  OFF=0000

if your relay board not use by this protocol. you can also write esphome as "write_lambda" way. i have tested, "write_lambda" to create switch also work fine. just need to create ON and OFF two command.

    write_lambda: |-
      ESP_LOGD("main","Modbus Switch incoming state = %f",x);
      // return false ; // use this to just change the value
      payload.push_back(0x1);  // device address
      payload.push_back(0x5);  // force single coil
      payload.push_back(0x00); // high byte address of the coil
      payload.push_back(0x00);  // low byte address of the coil
      payload.push_back(0xFF); // ON = 0xFF00 OFF=0000
      payload.push_back(0x00);
      return true;

Hello.
I need some help with the setup. I have bought a KC868-64 board and I would like to connect an RS485 meter to this board, specifically a DDS 238. Using ESP Home. Can you help?
Thank you very much.

use KC868-A16 work with KC868-H32BS by RS485 cable via modbus.

this is a demo , i have created one switch button in ESPHome, you can create many others.

KC868-H32BS use modbus command:
01 05 00 00 FF 00  CRC turn on relay1
01 05 00 00 00 00  CRC turn off relay1

make sure your relay board as these:
ON = 0xFF00 OFF=0000

if your relay board not use by this protocol. you can also write esphome as "write_lambda" way. i have tested, "write_lambda" to create switch also work fine. just need to create ON and OFF two command.

Hello everybody!

I am new to the ESP32 board and just got myself the KS868-A16.

My first choice was to use Arduino IDE to program my board.
After writing my first Sketch I found out the Debugging for the ESP32 board is not directly supported
Has anyone found a working solution for this as I would like to be able to see status, test and troubleshoot my code.
Tried to Google the subject but has not been able to find an easy fix.

I have been looking at other options like Tasmota & ESPHome and Home Assistant.
Does any of those two platforms has a debugger?
 
I preferer a standalone system instead using a dedicated system.


My project is for the time being a small home control of 6pcs indoor light controls, time controlled outdoor night-light with 3pcs PIR and dimmer, armed-disarmed indoor alarm system with 4pcs PIR sensors.

Any recommendation to which platform to use, Arduino, Tasmota or ESPHome as I would like to write of standard code. 

Any feedback is appreciateded
