1. use Gitpod, you just need a web browser: https://tasmota.github.io/docs/Gitpod/

2. for example:  we make a new tasmota firmware for ESP32 MATTER + enable PCF8574 i2c bus chip.
   

3. When compiling your build add the following to user_config_override.h
#define USE_I2C                                // Add support for I2C
#define USE_PCF8574                            // [I2cDriver2] Enable PCF8574 I/O Expander (I2C addresses 0x20 - 0x26 and 0x39 - 0x3F) (+2k1 code)
#define USE_PCF8574_SENSOR                  // Enable Mode1 inputs and outputs in SENSOR message (+0k2 code)
#define USE_PCF8574_DISPLAYINPUT            // Enable Mode1 inputs display in Web page (+0k2 code)
#define USE_PCF8574_MQTTINPUT                // Enable Mode1 MQTT message & rule process on input change detection : stat/%topic%/PCF8574_INP = {"Time":"2021-03-07T16:19:23+01:00","PCF8574-1_INP":{"D1":1}} (+0k5 code)

4. after SAVE the FILE, then run command:   "platformio run -e tasmota32"
Command "platformio run -e tasmota32"  is correct for ESP32 builds,  "platformio run -e tasmota"  is only for esp8266 builds.

5. after compiled, download "tasmota32.factory.bin". 
   

6. then use ESP DOWNLOAD TOOL write to ESP32 in address 0x0
   

7. after re power on of ESP32 board, you can connect with tasmota, config it with I2C SDA and SCL pins firstly, then you can see the PCF8574 option and MATTER option.

Hi, which board you show in the picture for SX1278 Wireless Transceiver Module Lora 868Mhz? It has Lora and a small OLED display :-) I want this!!!!

Hello,

I want to use a H32B and a H32B Pro with Home assistant.

For the H32B, I used this unofficial integration: https://github.com/fiLLLip/hass-components-sha. It uses the RELAY-SET- and RELAY-READ- commands; you can see the code here https://github.com/fiLLLip/hass-componen..._init__.py. This works very well.

The same code does not work for H32B Pro. Only about 50% of clicks on switches work, and I often get error messages such as 'Failed to call service switch/turn_on. 'NoneType' object has no attribute 'group''.

Is this normal? Do the H32B and the H32B Pro use different protocols? I found the page for the protocol used in H32B, is it not supposed to work the same on the Pro?

Thank you!

Good afternoon,

I need an help to choose the right KC868-A model (I don't want to make a mistake because I must buy 21 pieces....)
My hardware minimum specs :

1. the board must have an ethernet (rj45) port
   
2. min 5 releays NO/NC max load 1 A at 230v
   
3. I must connect to every board n. 4 temp sensors DS18B20
   

Can i get Firmware v1.0.9 same as the video tutorial - 2023 new "KCS" firmware for KinCony ESP32 board detailed explanation

KinCony ESP32 Tuya IoT adapter V2 let relay board or IoT devices easy integrate to tuya IoT platform. We have designed by ESP32 work with Tuya module. Tuya module will connect with Tuya cloud server, when using tuya phone app, message will send to tuya wifi module and decode by ESP32. ESP32 support use arduino IDE to write code, get the tuya message and send any command to RS485 or network device. it’s a good convert tool for smart home automation DIY.

You can add ESP32 Tuya IoT adapter, let your KC868-A series board can use voice control by alexa or google home speaker.

adapter support to use “Tuya MCU SDK Arduino Library”

KC868-H32B,KC868-H32BS …. HxB series smart controller will be easy support TUYA phone application, alexa and google home voice control function.

Hi,
I use KCS V2.2.2
Id like to use one button to do 2 different things:
-if single press do relay1
-if press and hold for 1sec do relay2

Can I do that? How?
Thank you

Hello!

Is it possible to use the 0-10v output as a pwm output? I want to control a heating pump with it.
The firmware would be ESPhome. I am attaching the pump PWM signal data.

esphome:
  name: pump
  platform: ESP32

wifi:
  ssid: "xxx"
  password: "xxx"

# Enable logging
logger:

# Enable Home Assistant API
api:
  password: "xxx"

ota:
  password: "xxx"

output:
  - platform: ledc
    pin: GPIO26
    frequency: 100 Hz
    id: pump_pwm

fan:
  - platform: speed
    output: pump_pwm
    name: "pump"
