Hello!

I hope you will be fine. I bought 4 KC868-A16 for trial purpose for my company. If suitable we will buy more But I am not able to program it until now. So I was thinking Kindly Can I get your WhatsApp so that any of your technical support Staff can guide me how to program KC868-A16 with  Arduino IDE software. 

I had connected the power and ethernet port with my laptop for programming. Also I had selected the board as Nodemcu32s and selected the right port. When I start uploading the your demo code, I don't why the program doesn't upload and give me the following error;

"Sketch uses 316512 bytes (24%) of program storage space. Maximum is 1310720 bytes.
Global variables use 21008 bytes (6%) of dynamic memory, leaving 306672 bytes for local variables. Maximum is 327680 bytes.
esptool.py v4.8.1
Serial port COM5

A serial exception error occurred: Cannot configure port, something went wrong. Original message: PermissionError(13, 'A device attached to the system is not functioning.', None, 31)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.
For troubleshooting steps visit: https://docs.espressif.com/projects/espt...oting.html
Failed uploading: uploading error: exit status 1"

Could you identify what I am doing.ad connected the power and ethernet port with my laptop for programming. Also I had selected the board as Nodemcu32s and selected the right port but I don't why the program doesn'
I will appreciate your help in this regard. 

Thankyou,

I just received the M30. And I don't know how to get it to work. I haven't found any documentation or user guide for the M30.
My scenario is to configure the M30 to provide measured data via MQTT to other systems.

I want to connect to M30 and configure it. But it looks like the ethernet connection is not working.
If I connect the M30 to the switch, LED on the ethernet port doesn't blink.

Hello,

After installation of IDE 2.3.4 on Windows 11 and inserted the link "https://dl.espressif.com/dl/package_esp32_index.json" in the preferences  The "esp32 by espressif Systems 3.1.1" is installed
I see only under "Tools" the board "esp32"
Under sep32 I see a lot of modules but no ESP32 Arduino Module. I cannot connect via the Com3 to my KC868-A16 REV:1.6
Can anyone help me with installation of the correct board and module to get the communication with my KC868
Great thanks
Theo

v2.2.12 improvement:
fixed MQTT bug.

Hi,
I'm trying to connect 2 analog temperature sensors to analog input on my A8 but I have 2 problems.

When the sensors are not connected, checking the voltage, the meter shows 1.062v (real value).

One problem is, that immediately after connecting to the board, the voltage drops to 1.015v.
While this could be handled and read correctly, as long as the voltage changes remain constant between temperatures - this sensor is connected in parallel with another board, so changing the voltage on it is also affecting the other board reading.

Second problem is, that esphome code I'm using to read the voltage is showing 0.68198v...
The code for that particular sensor I'm using is:

Hi guys, 

I am having issues with programming this module in arduino. 
1. need possibly a demo code to get the ethernet to work and how to work with its inbuilt adc, 
2.Also, the demo code in arduinoide for other features such as rs485 and co would be good as well. 
3. Can i connect a display screen to the socket for the 4g modemand hope i canalso use the port for sd card module for dat logging purposes. 

Pleas note, number one is urgent and most important to me. 
thanks
Dammy

Hello.
I set up an A16 device with the software version v.2.2.12. The display of the time on index page is still not correct. It should always follow the format YYYY-MM-DD HH:MI:SS.
Unfortunatlely the date & time is displayed like this: "2025-02.27 7:5:27" Please see attached image.

In addition to that, the IFTTT time function is not working. When time is reached, the configured output is not switched on.
What am I doing wrong?

How should i connect F16 to PC? Always got appear and disappear usb port shown. What should i do? Thanks

I have a problem that I can't solve. This is already my second board because I have a well-functioning A64 version, and now I'm trying to use the A128 version.
I'll start by saying that enabling MQTT (protocol->general->mqtt) is only possible for me on version v1.0.27. In firmware versions > v2 with IFTTT, it doesn't work—when I enable MQTT, the controller freezes, I can't access the web panel, and only a factory reset helps.
Only in version v1.0.27 does the controller not freeze after enabling MQTT. But here, I have another issue. When MQTT is enabled and I set any input to perform an action, after executing the action, the controller temporarily loses connection with the MQTT broker and then reconnects after a few seconds—I can't smoothly control the lights.
As I mentioned, I also have the A64 version, which runs on the same broker with firmware version 2.2.2, and everything works fine there. I have no more ideas on what could be wrong. I've checked the broker configuration, tried different settings, and nothing helps. I've also connected to external brokers, and the issue persists. I have flashed all your firmware versions onto the controller, and I can't get MQTT to work on any of them except for v1.0.27.

I'm trying to install a Wika A-10 Pressure Sensor/Transmitter 8-30VDC 4-20mA P# 13361091. This is the first time I've used a 4-20ma sensor. I've used other 0-5V and 0-10V sensors before with voltage dividers and have been successful.

Can you help me understand how the A1 and A2 Analog Inputs on the B16M work to convert the 4-20ma signal into a voltage and what I should use for the gain? ChatGPT is trying to explain it to me but it describes using a 250ohm shunt resistor. How do I know what internal shunt resistor(s) have been used to convert the signal to be readable by the internal ads1115 chip?

I will be using 12VDC to excite the pressure sensor which is rated for 8-30VDC. The Wika test report shows that the sensor should produce 4ma at 0 bar and 20ma at 2.5 bar (36.2595 PSI). Here is a snapshot of my YAML code for esphome so far:
