RS485 issue

Wed, 24 Jun 2026 19:10:38 +0800

Hi Kincony,
I have bought some of your B4M modules, and try to use the RS485 port.
I try to run the code here: https://www.kincony.com/forum/showthread.php?tid=8934

Code:
/*

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

 *

 * RS485 Communication Test

 *

 * This program is a simple test for RS485 communication using ESP32-S3.

 * It will send a message over RS485 and then read incoming messages.

 * The TXD pin is defined as GPIO 18 and RXD pin is defined as GPIO 8.

 */

#include 

// Define RS485 pins

#define RS485_RXD 39

#define RS485_TXD 38

// Create a hardware serial object

HardwareSerial rs485Serial(1);

void setup() {

  // Start serial communication for debugging

  Serial.begin(115200);

  while (!Serial);

  // Initialize RS485 Serial communication

  rs485Serial.begin(9600, SERIAL_8N1, RS485_RXD, RS485_TXD);

}

void loop() {

  // Send a test message

  rs485Serial.println("Hello from KinCony B8M!");

  // Wait for a short period

  delay(1000);

  // Check if data is available to read

  if (rs485Serial.available()) {

    String receivedMessage = "";

    while (rs485Serial.available()) {

      char c = rs485Serial.read();

      receivedMessage += c;

    }

    // Print the received message

    Serial.print("Received: ");

    Serial.println(receivedMessage);

  } else 

  {

    Serial.println("RS485 is not available");

  }

  // Wait before sending the next message

  delay(2000);

}

but cannot receive the data from RS485 port. The log shows that port is not available.
Can you help me troubleshoot this issue?

Switching power supply with A16

Mon, 22 Jun 2026 22:27:32 +0800

Dear all,

I'm replacing my old alarm system by kc868-A16 v3 and i would like to keep my 12v battery as UPS in case of power cut.
I have a 13.8v switching power supply but kc868-A16 doesn't work at this voltage.

Is it possible to use this power supply and how ?

If not possible, what could be the solution ?

Thank you for your help.

KCS v3 - Remote modification of Timer/IFTTT rules from Home Assistant

Sat, 20 Jun 2026 06:27:18 +0800

Hello KinCony Team,
We are using a KC868-A16 controller with KCS v3 firmware and Home Assistant integration.
Our project requires the following functionality:

Home Assistant should be able to modify fountain schedules (pump and lighting operating times).
The schedules must be stored inside the KC868 controller.
If Home Assistant, MQTT broker, network, or Internet connection fails, the controller must continue operating autonomously according to the last received schedule.

We have already successfully tested:

MQTT integration with Home Assistant
Scene Mode
Custom Protocol (UDP)
Local IFTTT rules
Local Timer rules

Our questions are:

Is there any official API (HTTP, MQTT, TCP, UDP, Custom Protocol, etc.) that allows remote creation, modification, enabling/disabling, or updating of Timer rules from Home Assistant or another external system?
Is it possible to remotely modify Time-based IFTTT rules and save those changes permanently in controller memory?
Is there any documented method to upload a schedule configuration to the controller programmatically?
If this is not supported by KCS v3, what is the recommended KinCony solution for a system where schedules must remain operational after Home Assistant, MQTT, network, or Internet failure?

Another question:
We can't find a way to create a schedule that works as a time range.
For example:

The pump turns ON at 09:00
The pump turns OFF at 23:00

The light turns ON at 18:00
The light turns OFF at 23:00

If KCS has a built-in feature that allows us to create, modify, and activate such schedules programmatically, it would solve most of our requirements.
Another question:
In IFTTT, we can only create a rule such as:

If time is 09:00 → turn pump ON

However, if communication with Home Assistant is lost at 09:05, the 09:00 event has already passed and the rule will not run again.
For example:

Pump schedule: 09:00 ON, 23:00 OFF
Home Assistant fails at 09:05
The controller switches to autonomous mode

In this situation, the pump will not turn ON because the 09:00 event was missed.
Could you please explain the recommended way to implement autonomous operating schedules in KCS v3 when Home Assistant may become unavailable, but the controller must continue operating correctly according to its schedule?
We are trying to avoid developing custom firmware and would like to use standard KCS v3 functionality if possible.
Thank you very much for your support.

Need Advice for New 3-Floor Smart Home Construction Using KinCony Controllers (Nepal)

Thu, 18 Jun 2026 22:47:03 +0800

Hi everyone ❤️,
I am from Nepal and will start building my new house this month. another controller, which is best for 2 floors, there are many channels needed for 50 channel need for 2 floors
I already have a KinCony AIO controller and would like to plan the smart home wiring before construction begins.
I have attached my floor plan. Could you please suggest:

Best switch type (momentary/dry contact)
I want to bypass the switch also
I place the floor-wise DB box and want to install it
Recommended sensors (presence, motion, door, water leak, smoke, etc.)
RS485 wiring recommendations
Any important things I should install now for future expansion

Any suggestions or examples would be greatly appreciated.
Thank you very much! ?
Jitendra

Thu, 18 Jun 2026 17:02:58 +0800

Hi Kincony,

I would like to request a KC868-A4 for an Open source university final-degree project (Type A): bridging a wired 230V PIR motion detector to MQTT (Mosquitto) using KC868-A4 + ESPHome over WiFi, alongside our existing Zigbee2MQTT setup. Documentation, wiring diagrams and code will be published openly (CC BY-SA 3.0)

Kind regards.

KCS v2 relay state after reboot

Thu, 18 Jun 2026 11:14:10 +0800

Hi,
In KCS v2, can relay states be automatically restored after a power loss and reboot, or do they always start from the default state?
Thanks.

Request for 230VAC LEDs / Downlight

Wed, 17 Jun 2026 14:08:37 +0800

Hello,

I'm currently building my house and i'm planning to be able to adjust the lighting in all my rooms (30 zones).

I came across your DIN rail modules, which I think are perfect. Great job!!

However, a have a quick question: how can I dim 230VAC dimmable LED spotlights / downlight from 0% to 100% without any flickering and which the real 0% (using a triac?) ?

Best regards

Benoit

The watch shows the wrong time in standalone mode.

Tue, 16 Jun 2026 04:06:16 +0800

KC868-A16v3, firmware v3.25.0, battery 3,05V.
The watch shows the wrong time in standalone mode. The controller is connected to a local network without internet access. Time zone - UTC+3.
Turn on the controller. Click "Synchronize browser time".
The controller's clock shows the same time as the computer's clock. Turn off the controller, and then turn on the controller. The controller clock shows the time 3 hours later.
Turn off the controller again, and then turn on the controller. The controller clock shows the time 6 hours later.

"Is there a feature or logic in the Kincony A4S firmware that supports the following switch behavior: a single press toggles the light ON/OFF, while pressing and holding increases the brightness, and releasing then pressing and holding again decreases the brightness?"
