KinCony ESP32 Tuya IoT adapter

Thu, 02 Apr 2026 15:22:11 +0800

Hi, I have two H32L along with two KinCony ESP32 Tuya IoT adapters. I use everything on Home Assistant, and it works well via "local tuya" integration (and a Tuya developer project). However, if I reboot the system, the two KinCony ESP32 Tuya IoT adapters don't connect and must be rebooted AFTER the router to connect. I'd like to port everything to "tuya local" integration, which is 100% local. Is that possible? Thanks as always

adaptor V2 and KC868 h32bs

hello

can you send me step by step, how to setup tuya adaptor V2 and KC868 h32bs.

Thank you

KC868-ATC v1.4 connect to H32 rev 2.3

Sun, 19 Jan 2025 00:23:07 +0800

Hello,
I have been trying for a few days to set up the KC868-ATC v1.4 with Tuya module to connect to KC868-H32 rev 2.3 and control the relays. I managed to set the KC868-ATC Tuya module and connect using Tuya mobile App (Android), however the button/switches are not responding.
The weird part is that I can connect to KC868-H32 using Vircom and the IP seems to be set to 192.168.2.160 (we are using 192.168.2.x ranges). From what I have seen in the referred videos is that I should also be able to connect using the browser however this is failing. KC868-H32 is connected to the router through Ethernet cable

I have even tried to set KC868-ATC v1.4 to use RS232 instead of wifi. This had the same negative results.

If you require more information please let me know.
Please help me with some ideas how to set this system. I assume that I might have to change the firmware on KC868-H32 as in Tuya it was showing H32B PRO
Thank you very much and I wish you a great day

KC868-ATC Tuya HRC Zehner rs232 integration

Sun, 03 Nov 2024 20:47:40 +0800

Hello,

I have purchased the KC868-ATC V1.4 and want to use the rs232 functionality to control a Heat recovery system.
I use the tuya app to control my house, however i am not sure how to convert this app and KC868-ATC to the full protocol functionallity in the pdf...

Anyone any ideas?

I have a tuya developer account and Arduino IDE, i have created a IDE code, but doesn't work, the connection to tuya is missing i think...

Tuya adapter V2 arduino source code - control KinCony KC868-Hx series relay board

Mon, 03 Jun 2024 08:28:32 +0800

these BIN file firmware and arduino source code work for KinCony KC868-Hx series relay board:
KC868-H32, KC868-H32L, KC868-H32W, KC868-H32BS, KC868-H32B
KC868-H16, KC868-H16W, KC868-H16B
KC868-H8, KC868-H8W, KC868-H8B

you not need connect any cable between Tuya adapter v2 and relay board. Because of it use by TCP connection, it use network.

if you want modify arduino source code, which relay board model to use, just uncomment the model command line.
first time run code, you need to set relay board's IP address, port, your router's ssid and password for Tuya adapter v2 by usb-serial port.
just send command as this: SSID:KinCony,PSW:a12345678,192.168.3.141,4196
serial port baud rate: 115200bps

here is arduino source code:

Code:
// USB set command     SSID:XXXXX,PSW:XXXXX,X.X.X.X,YYYY

// X.X.X.X is relay board IP address,  YYYY is relay board port.  SSID and PSW is your router's ssid and password

// for example         SSID:KinCony,PSW:a12345678,192.168.3.141,4196

// make sure your H8,H16,H32 relay board work with "TCP Server" mode.

tuya + h32l pulse

Sat, 18 May 2024 22:06:18 +0800

hello everything is fine??
I need to clear up a doubt.
I bought the Tuya adapter to put it next to my project, it worked fine, but I can't transform some channels into pulses, for example, curtain
can you help me

Tuya adapter V2 arduino source code - RS485 relay controller KC868-H32BS

Tue, 14 May 2024 10:18:04 +0800

This is sample demo let RS485 digital output device (KinCony KC868-H32BS controller) can work with Tuya app by internet. you can let your own RS485 relay board add to Tuya app.
added Tuya adapter v2, relay board will support alexa or Google home speaker for voice control directly.

KC868-ATC V1 dont work on Tuya

Sat, 20 Apr 2024 10:52:03 +0800

I received the board yesterday and start trying. The wifi state led blinks when its looking for conection, but after connect the led turn off, the switchs on Tuya app does not respond. After clean wifi config and connect again the app shows the switchs at the last change I did, and the wifi led star on and turn off after couple seconds. At the Tuya app shows all 32 switchs and the digital the inputs correct.

Need Assistance with KC868-ATC Modbus Master (RS485 RTU) Communication in ESP32

Wed, 29 Nov 2023 20:32:08 +0800

Greetings community,

I trust this message finds you well.

I'm currently engrossed in a project that requires the use of a KC868-ATC as a Modbus master using RS485 RTU to communicate with Modbus slave devices. Despite my efforts to create a simple program using the Modbus Master library for ESP32, I've encountered challenges and believe I'm missing some crucial details.

Could anyone kindly share a basic program or offer guidance on reading holding register data from a Modbus slave device using KC868-ATC as the Modbus master with ESP32?

Your insights and assistance would be immensely valuable. Thank you in advance!

Best regards,

TUYA_ESP32_Adapter arduino source code 7.1 -support TCP connection

Thu, 13 Oct 2022 09:53:49 +0800

this 7.1 source code version, have added TCP connection with KinCony's relay board by WiFi. so now you can use RS232 or RS485 or WiFi connect to KinCony's KC868-H32BS, KC868-H32B, KC868-H32L, KC868-H32 relay controller.
just config relay board IP port for router by KC868-Adatper's AP (AP name is KC868-Tuya) webpage.

here is firmware BIN file, you can download to ESP32 directly by USB cable:

 * LED D2: when D2-ON: ESP32 connect to relay board by TCP connection successfully

 * LED D3: when D3-ON: KC868-Tuya adapter work in RS232 or RS485 mode

 * LED D4: when D4 blink: ready to config Tuya wifi module for router SSID

 * LED D6: KC868-Tuya adapter power LED
