Hi! I was just setting up a KC868-D8 dimmer controller that I bought some time ago.

Initially, it came up without problems, and I was able to control the one dimmer circuit I attached to it using the Web interface. . It got an IP from the DHCP server in the LAN, I have it configured to give addresses in the 172.22.0.0/16 range.

Then I changed the passwords, since I don't like to have default passwords around for security. The server came back up again, but I couldn't log in, though I'm pretty sure I entered the correct password. So, thinking it would reset the password, I hit the reset button.

But now to the biggest problem: It does not connect to my network now.

I see no traffic from it in my logs, it doesn't contact the DHCP server, its MAC is listed as incomplete with arp, and there is also no response at 192.168.1.200:4196 (which is not strange, since that address wouldn't be allowed in my network).

What could be the reason for this and how do I fix it?

Could it possibly be that it insists on the 192.168.1.200 address, and so it doesn't ask the DHCP server?

Goodnight,

I have a problem with my KC868 A4 board - I made her code, to use it with alexa, but in about 10 days (it varies a lot) when asking for a command through alexa it doesn't find the devices, as if it had no wifi connection, so I click the reset button and it works normally again, has this happened to anyone?

thanks in advance

Hello,

When I use the momentary switch of a relay in combination with Mqtt, I am able to make the kincony ethernet "hang".


It seems to occur when the Kincony had to process commands during the momentary switch.
  - Note: while I do not receive the state on mqtt, the relay have well-executed the momentary switch
  - When a bug occurs:
     - the ethernet is completely stuck; no ping, no HTTP server, no mqtt
     - HTTP UI for wifi (on another IP is still working)
     - Only possible recovery is a Hard reboot (reset of wifi is not working)


My reproduction method: 
 - Put Relay1 with momentary switch 1 seconds
 - send 2 mqtt command:
    - `mosquitto_pub -t "relay32/dddd/set` -m "{\"relay1\":1}" 
    - `sleep 0.5`
    - `mosquitto_pub -t "relay32/dddd/set` -m "{\"relay1\":1}"


I also reproduced it with the embedded HTTP page just by insisting when relay state is "wrong".

I tried to update to the latest version (44) but it does not seem to help.


Have you any idea on how to mitigate that?

Hi, I have some questions regarding the KC868-A16 board, please answer as follows:

1. I have a INPUT signal which is either connected to (common) GND or 5V. Will the inputs recognize this correctly?

2. I have an actor, type 1 (OUTPUT) which supports 5V and needs to be connected to GND when switched. Will this work?

3. I have an actor, type 2 (OUTPUT) which will need 15V output. Will this voltage be okay (instead of 12V)?

1. latch mode: Button1

    on_press:
      then:
      - switch.toggle: e16s_output1


2. inching mode: Button2

    on_press:
      then:
      - switch.turn_on: e16s_output2
    on_release:
      then:
      - switch.turn_off: e16s_output2 


3. momentary mode: Button3

    on_turn_on:
    - delay: 1000ms
    - switch.turn_off: e16s_output3


4. interlocking mode: Button4-Button5

interlock: [e16s_output5]

interlock: [e16s_output4]
