we have designed Z1 by ESP32S3 + Tuya ZSU Zigbee 3.0 module. It based on ESP32-S3-WROOM-1U (N16R8) wifi chip. it support use by ESPHome for home assistant for smart home automation DIY. Z1 use KCS v3 firmware, it support home assistant auto discovery function by MQTT, so without write any config code (zero code) for home assistant. KCS v3 support KinCony board integrate to Loxone Miniserver and Apple HomeKit.

You can define RF and IR buttons to control TV or air conditioner or other IR devices by IR signal.
Z1 can pair with zigbee3.0 standard protocol products. create IFTTT command for zigbee sensor, so that zigbee sensor automatic send command to relay board or other devices using customize command.

You can write any code by Arduino IDE / Micro Python / ESP-IDF development tool to ESP32-S3 module. We will supply Arduino demo code for different samples. Everyone can modify and change the code for your own smart home automation system project.

Due the lack of 63amp contactors in 12v. It's possible to use a power supply with 24v for the  a24pro? Not for the relay.. to the unit itself? Thanks a lot!

1. Development Environment Setup
   • Arduino IDE (tested with both version 1.x and 2.x)
     
   • Official ESP32 core installed via URL:
     
     
     Code:

     https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
     
     
   • Selected board: ESP32 Dev Module
     
   • Baud rate set to 115200
     
2. Sketch Upload
   • Tested official KinCony sketches for KC868-A2 with SIM7600
     
   • Tested custom sketches for sending AT commands
     
   • Tested with PSRAM disabled to eliminate
     
     
     
   • Compilation and upload completed successfully → ESP32 is working correctly
     
3. Connections and Power Supply
   • KC868-A2 powered with 12V as per manual
     
   • LTE antenna connected to MAIN port of SIM7600 (not AUX/GNSS)
     
   • Verified presence of power and indicator LEDs:
     • Red power LED solid on
       
     • Green modem LED blinking continuously
       
4. SIM Cards
   • Tested two different SIM cards in two different SIM7600E modules → no response
     
   • SIM cards confirmed working in a mobile phone
     
   • SIM PIN disabled
     
   • Contacts cleaned
     
   • Correct insertion verified
     
5. AT Command Tests from ESP32
   
   → no response
   
6. Serial Monitor shows nothing or “modem not found”
   
7. Alternative Checks
   • Attempted direct connection via USB MODEM to PC (drivers not easily available)
     
   • Tried alternative SIM slots and different LTE antennas
     
   • Evaluated alternative GSM modules (SIM800C, SIM800L) → working in other projects
     
   • Conclusion:
     The ESP32 works and communicates correctly via USB, but the SIM7600E module does not respond to any AT command, even after testing with two different units, proper power supply, and a suitable LTE antenna.
     

I have a KC868-A16v3 and I've created an IFTTT rule that says:
IF DI16 False and DI1 False then DO1 ON 1 then Delay 2 s then DO1 OFF 1 and it works but when i change DI16 to True it turns DO1 ON again for 2 seconds.  It only does it one time and then stays off if DI16 is True?
I am controlling the state of DI16 with a relay that I turn ON or OFF in HomeKit with a smart switch.  I am trying to use the KC868-A16 as an alarm control and DO1 is the siren so I don't want it to turn on again when I turn the system OFF (DI16 TRUE).  Any suggestions as to why this is happening and how to correct it?  

Hi
Brand new  KC886 AI . i have followed the instructions, however am unable to get the web interface after firmware update.

firmware update appears successful, and i can see the MAC addresses.
i am not getting a Wifi AP come up.

AP:  14335C090AED  STA:  14335C090AEC
BT:  14335C090AEE  ETHERNET:  14335C090AEF

i can ping 192.168.1.200, however get "Connection Refused" message..
i have tried with various Web browsers

i am directly connected with LAN cable, no router in between
have set static on my laptop to same IP Range

the SCAN DEVICE TOOL does not find the board when i scan.



can you please assist

Thanks

I have a 24v 4-20ma Pressure transmitter connected to A3 but the raw measurements even with zero pressure fluctuate.
What is the best way of connecting this for maximum accuracy and stable numbers.
In ESPHome, this is mu code and the Zero Pressure fluctuates by 100


  - platform: adc
    pin: 6
    raw: true
    name: "F16 A3 Current"
    update_interval: 5s
    unit_of_measurement: mA
    attenuation: 0db
    samples: 100
    sampling_mode: avg

Hi I have just bought 3x F16 Smart controllers and want to know if you have something that can do the something to control some heating elements.

I want to monitor the current on 4 elements to see if theyre turned on (I dont need to count the power consumption) just on or off, and then I need to have 4 relay outputs so that I can turn the elements on or off through a 3 phase contactor.

Do you have anything like that (an 8 channel would be good).

I really like the DIN rail design of the F16 so something like that would be great.

Board Model: KC868_A16

Web interface on Ethernet ....

Originally I was able to change the user name and password. However, at some reasonably early setting changes, the KC868 stop responding over Ethernet. I noted the port actiivity seemed to be intermittent. In other words, the activity lights would flash for perhaps a second and then turn off. The board seemed to be in continuous reset? 

Anyhow, I decided to re-flash the FW (with the same version above). That appeared to be successful and permitted me to login with the default UN/PW (admin/admin). 

However, the minute I went to change the 'System', I immediately was presented with the login screen again. Several repeats later, ie, I login, go to 'System', login, go to 'System' I figured maybe an 'ERASE' cycle with ESP's firmware tool would help .... it didn't. 

Why can't I now change the User Name and Password even though I could on the initial configuration. 

PS: Clicking on the upper right 'Admin' -> 'Change Password' has the same cycle of repeatedly asking for login info. 

TIA.
