Problem:
Relay 1 switches ON and OFF intermittently when WiFi Access Point (AP) mode is enabled.
I have performed several tests using a simple Arduino sketch with no relay control code at all.
Test results:

Code:
WIFI_MODE_NULL
– WiFi disabled: No relay clicking.
Code:
WIFI_STA
– Station mode, without connecting to any network: No relay clicking.
Code:
WIFI_AP
– Access Point mode: Relay 1 starts clicking intermittently.

Additional information:

The DS18B20 temperature sensor on GPIO13 works correctly in all tests.
I have tried a different power supply. The problem remains.
No external loads or devices are connected to the relay outputs.
Relay 1 is the only relay that clicks.
The LED for relay 4 stays constantly illuminated.

My questions:

Is this a known issue with the KC868-A4?
Could WiFi AP mode interfere with GPIO2 or the relay driver circuit?
Could this indicate a hardware fault on my board?
Is there a recommended solution?

I would appreciate your help in identifying the problem.
Best regards

Firmware: ESPHome with ESP-IDF framework
Connection: Wired Ethernet (LAN8720)
Sensors tested: Konnected waterproof DS18B20 temperature probes
Verification date: October 19, 2026
1. Overview
The KC868-A8 V1.7.1 has a six-position connector providing four independent DS18B20 temperature sensor data connections, 3.3 V power, and ground.
The connector terminals are not individually labeled on this board revision. The following pinout was established through electrical measurements and successful operation of DS18B20 sensors using ESPHome.
All four temperature inputs have been tested successfully.
2. Verified connector pinout

              USB-C

This represents the vertical orientation shown in the board photographs, with terminal 1 nearest USB-C.
3. Electrical verification
With the board disconnected from power:

Terminal 1 showed continuity to the PCB's 3V3 test point.
Terminal 6 showed continuity to power supply ground.
Terminals 2, 3, 4, and 5 each measured approximately 4.7 kΩ to terminal 1.

With power applied and no temperature sensors connected:

Terminals 1–5 each measured approximately 3.29 V relative to ground.

The four 4.7 kΩ resistances are consistent with pull-up resistors for DS18B20 OneWire communication.
No additional external pull-up resistors were needed during testing.
4. Sensor connections
The Konnected waterproof DS18B20 probes used in testing have the following wire assignments:
Probe wire
Connection
Red
+3.3 V — terminal 1
Yellow
OneWire data — terminal 2, 3, 4, or 5
Black
GND — terminal 6
All four temperature inputs share the same power and ground terminals.
The wiring colors are specific to the probes tested. Verify the pinout of other manufacturers' probes before connecting them.
5. ESPHome configuration
The following is a complete example for the KC868-A8 V1.7.1, retaining all eight relays and eight optically isolated digital inputs while configuring S1–S4 as temperature inputs.

6. Test results
Two Konnected DS18B20 probes were used for verification.
S1 and S2 were successfully operated simultaneously, producing valid temperature readings in Home Assistant.
The second probe was then moved between the S3 and S4 connections, and both were successfully detected using their respective GPIO assignments.
All four data inputs are therefore confirmed operational.
Because each input uses a separate OneWire bus, up to four temperature probes can be connected using this configuration, with one probe assigned to each input.
7. Important observations

The eight DI1–DI8 optically isolated inputs are separate from the four dedicated temperature inputs.
GPIO32 and GPIO33 must not be configured simultaneously as binary inputs and OneWire temperature inputs.
The connector's 3.3 V supply and ground are shared among the temperature sensors.
Other KC868-A8 board revisions may use different physical terminal arrangements.
This pinout was verified on PCB revision V1.7.1 and should not be assumed correct for other revisions without checking.

8. Conclusion
The KC868-A8 V1.7.1 supports four independently connected DS18B20 temperature sensors using GPIO14, GPIO13, GPIO32 and GPIO33.
The six-terminal sensor connector has now been electrically mapped and all four OneWire data connections have been verified through actual temperature sensor operation.
These findings are provided to assist other KinCony KC868-A8 users and to supplement the manufacturer's existing documentation.

I received a KC868-AGv3 and installed KCS_AGV3_V3.27.2 on it. I'm struggling to get it to work with my ceiling fans (brand / model is CARRO USA Osborn).

I can successfully listen and capture signals from the fan's remote, but transmitting them from the KC868-AGv3 doesn't work with the fan. I tried settings of 10, 30, and 100 for the "Adjust Repeat Count" option, without success.

How can I debug this further?]]>
I received a KC868-AGv3 and installed KCS_AGV3_V3.27.2 on it. I'm struggling to get it to work with my ceiling fans (brand / model is CARRO USA Osborn).

I can successfully listen and capture signals from the fan's remote, but transmitting them from the KC868-AGv3 doesn't work with the fan. I tried settings of 10, 30, and 100 for the "Adjust Repeat Count" option, without success.

I bought a KC868-A16v3 ESP32-S3 16 channel GPIO module and realised that I need 10 more outputs. What would be the best approach? buy another one and run both? or is there any alternative?
I am using it to connect the outputs to SSR to have no mechanical noise on activation.

Thanks]]>

I have a KC868 A8, after watching your video on Youtube I downloaded firmware KCS_KC868_A8_V1.9.1 and KCS_KC868_A8_V2.2.20. I am able to flash both versions but it doesn't show all option on its webpage or incomplete options. fx. I don't see the option to bind input and output port together.
Could you please send me the ulr link to download the compatible firmware version.

Best regards

I have a Force sensitive resistor: https://www.aliexpress.com/p/order/index...76dbGk3szT

I'd like to know if it's possible to directly connect it to the board and use it as switch in esphome.

Thanks!]]>

I am planning a project based on the KC868-A16 v3.1 (REV:1.6) board. My peripheral types include 5V digital sensors (TTL/CMOS) and low-power 5V loads.

Could you please help me with the following technical questions:

LO0 and LO1 with 5V: The official documentation specifies 12V/24V for the LO0 and LO1 power supply. Is it safe and functionally possible to apply a 5V external voltage to these specific channels instead?
Onboard 5V VCC Usage for LO0 and LO1: Can I use the internal 5V VCC rail from the board to power the LO0 and LO1 loads? The total load current will be under 1A, which is within the XL1509-5 regulator capacity. Are there any internal limitations preventing this?
16 Digital Inputs with 5V logic: How can I modify all 16 Digital Inputs (INPUT1 and INPUT2) to safely and accurately read active 5V digital signals (TTL/CMOS)? What is the exact hardware modification procedure for the PCB?

Thank you.]]>
