  kc868-server16
Posted by: fdcemb5 - 07-13-2025, 08:37 PM - Forum: DIY Project - Replies (3)

My KC868-server16 refused to boot, and it is just blinking as shown in the video. I have inserted the SD card into the standalone Raspberry Pi 4 module, and it booted. I am wondering what to do next. I have tried several times to reboot without success.

  Error Flashing new KCS firmware using ESP32 Download Tool
Posted by: steven22 - 07-12-2025, 07:36 AM - Forum: KC868-A2v3 - Replies (12)

Hi everyone, I'm new to Kincony products and this forum. I recently bought a Kincony A2V3.1 board to test these products and their integration with Home Assistant.
Once the board arrived, I connected it to my router via LAN cable, but I cannot see any IP address on the A2V3 screen, nor can I find it on my network.

For this reason, I tried to reflash the KCS v3 firmware using ESP32 Download Tool V3.9.2 and entering download mode (turn off → press S2 button → turn on power → release S2).
However, when I press "start" on the ESP32 Download Tool, I get this error:

Code:
1 kill
test offset :  0 0x0
case ok
test offset :  0 0x0
case ok

no log file output ...

I already tested it with different USB cable, different PC and different power supply. But getting always same error.

Here a screenshot from ESP32 Download Tool V3.9.2:
   


Can you please help me debugging this issue?

regards,
Stefano

Question MCP23017 interrupt pin
Posted by: rboers - 07-09-2025, 02:03 PM - Forum: KinCony Server-Mini / Server-16 Raspberry Pi4 relay module - Replies (2)

I'm writing my own program in C/C++ and I was wondering if the interrupt pins of the MCP23017 chips are connected to the GPIO pins of the Raspberry Pi? If so, which GPIO pins are used?

Hello. Please help me set up the KC 868-16A KinCony TS Tiny RS485 SHT30 homeassistant bundle. I checked the sensor using a USB RS485 converter and it works. I connected it to the KC868 - 16a and can't figure out how to set it up.

Question CM5 compatible?
Posted by: rboers - 07-09-2025, 07:56 AM - Forum: KinCony Server-Mini / Server-16 Raspberry Pi4 relay module - Replies (1)

I really like this server, but the CM4 is a bit slow for my project.
Can a CM5 module be used in the Server-16 server?
If not, will there be a CM5 compatible Server-16 in the near future?

  How to configure HTTP post for Webhook
Posted by: land88 - 07-08-2025, 08:40 AM - Forum: KC868-A16S - No Replies

Hi,

My KC868A16s is connected to internet with LAN port, WIFI off (LAN IP 192.168.1.200, mask 255.255.255.0, Gateway 192.168.1.1).

It get the Board time to internet, no problem, so I think the KC is really connected to internet, it is not behind a firewall.

In custom protocol, I create Custom1, with :

"routeur = HTTP POST", "HEX : Empty", "Message :Empty" and "URL(Otional)= https://xxxx.synology.me/api/webhook/Tem...AT_G_21deg", this url is my webhook that is open on internet

With a Pc connected to internet, in chrome  this url turn on my webhook on my home assistant (boolean ON), but if I run the custom1 in IFFTT, I get "success" on KC but in reality Nothing appears to my home assistant. 

An other isue, when I run this custom protocol, I loose the connection to the board, so I must reboot the board to local access to the web interface !

I think I have an issue to configure this custom protocol.

Can you help me ?


Thanks.

  KC868-A16v3 more 1Wire Temp-Sensor per Pin
Posted by: CarMagician - 07-07-2025, 02:34 PM - Forum: KC868-A series and Uair Smart Controller - Replies (5)

Hello, 
I got the KC868-A16v3 Board today.

There are three dedicated pins for 1Wire Sensors: 
1-wire (pull-up resistance on PCB):
1-wire1:GPIO47
1-wire2:GPIO48
1-wire3:GPIO38

Is there a way to connect more than one sensor per pin?
I combined two sensors and hooked them up to HT1, there is no communication with the sensors. 
If I only connect one sensor I can read temperature. 

I need more than 3 temperature sensors so I thought about connecting all of them together. 
Had an other project with a normal ESP and there it was possible with 6 sensors on one pin. 
I would group them together in pairs of 5 for my project.  

Any hints?

Regard
CarMagician

  RS485 in Home Assistant / B16 / KC868-HAV2
Posted by: petermac - 07-07-2025, 10:05 AM - Forum: B16M - Replies (7)

Have a fresh B16M with latest firmware, has auto discovered by MQTT in Home Assistant.

Also have a KC868-HAv2 wired as per examples.  I can see the button inputs when using the PC software.

I have turned on RS485 in B16M protocol page with the same settings as per the KC868-HAv2.

How do I achieve the next step of having these button inputs active in Home Assistant - please ELI5.
