I have a KC868 A4 board and for some reason the relay 02 stopped working, in some measurements I verified that there is no voltage coming out of the esp32 (output burned) do you have any reserve IO ratio?

How do I retain the state changes trigger from 12vdc wall switch that triggers the existing momentary relays? Please take a look at the existing relays and the wiring in the attached picture, all the yellow wires are triggers to those Finder relays. When I use the trigger from the 32BS controller both the apps and wall switches are in sync because the existing relays and triggers keep the wall switches in sync. But if I trigger via the wall switch, the app and the controller are not able to retain any state. Where the existing trigger wires (yellow for +ve and black for ground) should go to 32BS controller so the states between the controller, app and the wall switches are all in sync? 

Thanks much

Hi
I configured the device kC-868-H32B
Ethernet on UDP server
And wifi on TCP server

Home smart app communicate fine with controller, but 1. Kbox not working with controller and send java error with fault communication please see attached snap shot. Neither when ethernet cable connect not disconnected.
2. Can i use some output say 2 out of 8 terminal block connect to certain phase R and 3 on ohase S and 3 on ohase T?
3. How i can control the controller on my PC ,all software on Website didn't communicate with controller.
Thank you

Because there are many Android phone models, some may have compatibility problems. When you delete old KBOX app, installed a new version from Google Play Store , open app crashed. You can download and install this KBOX-debug version. 

  KBOX-RELEASE-202202261520-log.zip (Size: 22.42 MB / Downloads: 296)
download this ZIP file , after unzip, install the "KBOX_20220112_log.apk".

when you open the app , crashed, it will save the debug data on your phone via log file. You will find the log file at here:

You can send to us this file by Email to hificat@163.com or post to our forum.

your phone brand, model, android OS verison. Then our software engineer will test it and make adaption work for you. if we solved, we will send you a new application APK file.

what is the input voltage of the colb ports?

Where can I get the latest firmware for the h32b?

Hello all.

System:
KC868-A4 board with Nextion NX8048P050-011C-Y display.

Problem:
UART communication with this particular display. Other 2.4 inch Nextion works well.
Possibly issue with TTL level.

Electrical connection info:
RS323 chip (SP3232EEN) removed from the KC868-A4 board.
The RX and TX of Nextion are connected directly to GPIO_16 and GPIO_17 of ESP32.
We have tried to use other GPIO's of ESP32. Nothing works.

The solution which works:
Replacing ESP32-S with original ESP32-WROOVER.

Question:
1) Can anyone suggest a simplier solution?
2) Is there any way to force Nextion to operate on 3.3v TTL level?
3) Can we connect Nextion to RS232 connector directly without removing SP3232EEN?

Hey,

i'm searching for a solution to control warm white/cold white 24V stripes from KC868-A... (esp32). can you recommend something?


in the past i use H801 to control 24V stripes. But i want to control it over your kc868 board to have a direct connection from switch to lamp

1. IPCamera SDK update
2. Adaptation iOS15.3

you can update by Apple Store, search "KinCony Smart Home"
