comme je suis debutant en arduino/ESP32S3, il me semble que la syntaxe manquant devrait comprends une fonction disable par fonction mais sur pas encore un as en arduino..mdr
j'ai besoin de votre lumiere merci d'avance. cela parce preparant le code pour le relay T16M.
la config : AIO maitre , T16M : Esclave pour compense le manque d'entrées /sorties de l'aio Hybride en reseau modbus , avec un ecran 7 pouces en Modbus . pour la programmation suis partir sur un melange en arduino avec EditeurPlc pour la partir PLC.
en autre , pour ce dernier , on doit declarer les variables externes ESP32S3, donc partir programmation sur le T16M me semble une bonne idee , merci de votre reponse.

T16M not responding on USB

Sun, 04 Jan 2026 20:04:07 +0800

Hello,

I have 2 T16M.

I am building a Wiegand door lock controller with ESPHome firmware, and am proceeding well.

I am currently using my second T16M with a Wiegand S20 keypad via a 5v - 3v3 logic level shifter.

However when I was using the first T16M, I did not use the 5v - 3v3 logic level shifter.
After some time of development using ESPhome it stopped responding via USB.
I had assumed I damaged the T16M.

You have advised that "you can connect Wiegand D0 and D1 to T16M free GPIOs directly, not need logic convert.", so therefore my assumption was incorrect.

I have seen in another thread that you can reset the T16M using the DW button while power-on.

Using that method has not made the USB work.

What can I do to make the USB work again?

Thanks, Rob.

T16M ESPHome and EPROM

Sat, 03 Jan 2026 20:05:41 +0800

Hello,

In the pin definition for the T16M, it shows the Eprom on the I2c bus.

How can we use the Eprom in ESPHome, and what is the size of the storage?

Thanks, Rob

Wiegand and GPIO on T16M

Sat, 03 Jan 2026 20:02:40 +0800

Hello,

I have a T16M (ESPHome), and I need to connect 4 Wiegand keypads (8 GPIO required). There are 7 GPIO, and 2 RS485 available.

Are the RS485 connections just a UART, and can be used for a Wiegand D0/D1 ?

------

I have noticed in your videos on Wiegand that you use the UART rx/tx connections on the example boards.
Is that because they are 5v logic, and are required to connect the 5V D0/D1 from the Wiegand keypad?

I assume the ESP32 will be damaged if I connect the D0/D1 to the GPIO connections of an ESP32 based board like the T16M?

Thank you.

Rob

T16M Output after reset

Fri, 12 Sep 2025 21:15:16 +0800

Just received myT16M in the mail this morning and I'm performing some test.

I installed the KCS 3.12 firmware and the servers webgui etc came up as expected.

Under the tab System there is this option: "Keep Output After Restart"
With this enabled I expected the outputs to com up in the last known state before restart or powertoggle, but all outputs comes up in a off state

I2C and UART on GPIO

Mon, 01 Sep 2025 23:03:30 +0800

Hello,

While T16M board doesn't explicitly have I2C and UART connectors as per the product description, I was wondering if using GPIOs can be a way to have I2C and UART interfaces.
The documentation says GPIO ports exposed on screw terminals (GPIO8, GPIO9, GPIO10, GPIO15, GPIO16, GPIO17, GPIO18) have pull-up resistors and can be used for 1wire sensors.

My questions are:
1. What is the pull-up resistor value? 4.7k?
2. Is there ESD protection diode for these pins?
3. Can these GPIOs be used for I2C and UART? (typically: GPIO8 and GPIO9 for I2C, GPIO16 and GPIO17 for UART)

Interrupt when Input is triggered

Fri, 04 Jul 2025 07:05:28 +0800

Hi,

Is it possible to configure an interrupt for when an Input is triggered, to avoid having to constantly poll the inputs for state change?

Thanks

USB Connection not recognized

Mon, 30 Jun 2025 10:54:47 +0800

Hi,

I am connecting my T16M to my PC with a USB for programming. The device is also powered with 24V, and is ON correctly.

The COM port does not appear in my device list. I tried installing CH340 and CP210 drivers manually, but it still does not appear.

Any tips on how to resolve this?

Thanks

Temperature is not send to Loxone

Tue, 03 Jun 2025 18:39:27 +0800

Hello, over the weekend, I got the T16M module up and running, and I was able to establish communication with my second-generation Loxone miniserver without any problems. Using UDP, I am able to read the on/off states of the DO, etc.
The only thing that isn't working, and I don't know if I'm doing something wrong, is reading the temperature status. I have a standard DS18B20 1-wire temperature sensor connected to the T16M board, I set the sensor in the board configuration and I can see the temperature(channel 1). Everything works without any problems. However, after setting the virtual input in Loxone, nothing happens. I monitored the UDP monitor in Loxone and no UDP command carrying temperature information reaches Loxone. Only commands for reading/controlling DI and DO. Is this a firmware error? Or does something else need to be set/enabled in the configuration for the temperature to be sent to Loxone?

Just to note, I am using the latest version of KCS3 firmware available right now.

Thank you in advance for your help.

Digital Out Connections

Fri, 02 May 2025 10:32:53 +0800

Hi

Is it possible to connect the first DC terminal to +24V so that outputs 1 to 8 get connected to +24V, and connect the second DC terminal to GND so that outputs 9 to 16 get connected to GND?

Serial Monitoring

Wed, 30 Apr 2025 11:03:51 +0800

Hi,

I am using Serial.begin() and Serial.println() but I see nothing in my Serial Monitor (Platformio). What could the problem be?

I am using 115200 as monitoring speed (configured in platformio.ini) and my Serial monitor is configured with the same rate.

I am using the demo code below:

Code:
/*

* Made by KinCony IoT: https://www.kincony.com

*

* This program reads 16 input states from a PCF8575 I/O expander and

* controls a corresponding 16-channel relay module. When an input pin

* is LOW, the corresponding relay is turned ON (LOW means ON for the relay).

* When the input pin is HIGH, the corresponding relay is turned OFF.

*

* Pin Definitions:

* - SDA: GPIO 11

* - SCL: GPIO 12

* - Input I2C Address: 0x24

* - Relay I2C Address: 0x25

*/

#include         // I2C communication

#include      // Library to control the PCF8575 I/O expander

// Define I2C pins

#define SDA 11           // SDA pin

#define SCL 12           // SCL pin

// I2C addresses

#define INPUT_I2C_ADDRESS 0x24   // I2C address for the input PCF8575 module

#define RELAY_I2C_ADDRESS 0x25   // I2C address for the relay PCF8575 module

PCF8575 pcf8575_IN(INPUT_I2C_ADDRESS);    // Create an object for the input PCF8575

PCF8575 pcf8575_RL(RELAY_I2C_ADDRESS);    // Create an object for the relay PCF8575

void setup() {

  // Initialize I2C communication

  Wire.begin(SDA, SCL);

  // Initialize serial communication

  Serial.begin(115200);

  // Initialize input and relay modules

  pcf8575_IN.begin();

  pcf8575_RL.begin();

  // Turn off all relays at the start

  for (int i = 0; i < 16; i++) {

    pcf8575_RL.write(i, LOW);  // Assuming relays are LOW when OFF, setting all relays to OFF initially

  }

  Serial.println("System started: Input state controlling 16 relays");

}

void loop() {

  uint16_t inputState = 0;

  // Read the state of 16 inputs

  for (int i = 0; i < 16; i++) {

    if (pcf8575_IN.read(i)) {

      inputState |= (1 << i);  // If input is HIGH, set the corresponding bit

    } else {

      inputState &= ~(1 << i); // Otherwise, clear the corresponding bit

    }

  }

  Serial.println("Test Point...");

  // Control the relays based on the input state

  for (int i = 0; i < 16; i++) {

    if (inputState & (1 << i)) {

      pcf8575_RL.write(i, HIGH);  // If input is HIGH, turn the relay OFF

    } else {

      pcf8575_RL.write(i, LOW);   // If input is LOW, turn the relay ON

    }

  }

  // Delay for 500 milliseconds

  delay(500);

}

PlatformIO Programming

Tue, 29 Apr 2025 18:25:49 +0800

Hi, NooB Here.

Trying to program the ESP32 in PlatformIO:

1. Which ESP32 S3 chip should I configure when creating the project in PlatformIO?

2. How do I make it connect to upload? Do I need to hold a button before uploading? I tried holding the DL button but it didn't connect. Same for the RST button.

Thanks

T16M discovery on linux

Wed, 26 Mar 2025 00:50:52 +0800

Hello,

I flash m'y T16M with the esp tools in Ubuntu following the procedure I found on the forum.
I put the KCS V3 firmware

But now when I plug the board to my router I am not able to find the ip. The orange led in ethernet port on the board blink. The green one is off.

I can not use the discovery tool, because I am on linux.
Do you have a tool to recommande.

I also search to connect to the wifi Access point. But It does not appear. I read that I have to press a button to re enable the wifi Access point, but which button (I saw dw and reset near antenna), and how to proceed (press before power on, at anytime...).

Thanks for your help

Dummy question: non-zero voltage between off OUTPUT pin and GND?

Sun, 23 Mar 2025 09:25:55 +0800

I'm currently toying around with the T16M before putting it into a wall and calling my project "working".

While experimenting, I started messing around with measurements ( hence my questions on https://www.kincony.com/forum/showthread.php?tid=7423 ).

I've wired my board similar to what I've found in these posts:

* https://www.kincony.com/forum/showthread.php?tid=7211
* https://www.kincony.com/forum/showthread.php?tid=2221 (this schematic is really clear, by the way, thank you!)

While testing out the board, I noticed that the voltage between `V-` and a disabled `V+` pin (see picture below) is **non-zero** (measures 2.385V).

I'm wondering if something is wrong with the board, or if the ESPHome settings don't completely disable the pin?
It may also be a misunderstanding of mine in how MOSFET-based switching works, so feel free to also tell me that my use-case is wrong

Cross units communication

Sat, 22 Mar 2025 03:13:06 +0800

Hello

Assuming I have several units of T16M and/or B16M connected via Ethernet to the same net. Is it possible to configure them to operate together? For example, can I define a digital input of one unit to control output ports of another unit (of the same model type)? Which protocols / SW approaches allow such cooperative operation and which aren't?

Thanks,
Elad
