KC868-A16 IR Input

Posted by: cyberrailpete - 04-20-2025, 05:33 AM - Forum: KC868-A16 - Replies (11)

	Hello. I have a KC868-A16 - Great board. I have a number of IR sensors that need to send back state via MQTT to different topics so have had to write custom sketch in Aurdino IDE. Problem is the sensor never goes inactive. I have tested the IR with a meter and voltage drop on digital out when active and high when inactive. KC868-A16 seems to be 12v on the input which is weird. Help please!

RF Transmitter not working in ESPHome

Posted by: johnsmith8439 - 04-19-2025, 04:20 PM - Forum: KC868-AG / AG Pro / AG8 / Z1 - Replies (4)

Hello,
I installed ESPHome on the KC868-AG. RF receiver works, I can receive RF signals from the smart plug's remote:

[23:17:05][I][remote.rc_switch:261]: Received RCSwitch Raw: protocol=2 data='10010010001010100110110110010011'

But transmitter doesn't work, I cannot control the smart plug with RF using the transmitter.

The log after using transmitter:

	Hello One of binary input stop working.. I checked and translator was damage. I do not know-how how, but it could be protect emc or overload. I just replace them, but I wojny about induction when I will connect them to 20m ftp.

Soil moisture sensors

	I bought the next sensor to experiment: Soil Moisture Sensor https://a.aliexpress.com/_ExqUPDK Powered 3.3v, gnd and tried AO on AI (9-16) & DO on DI (1-8). No change seen on inputs of AIO when I dipped sensor in water and out. Any ideas?

24V Support

Posted by: yawniek - 04-18-2025, 05:06 PM - Forum: Suggestions and feedback on KinCony's products - Replies (2)

	Hi, It would be good to be able to see more prominently which products support 24V input voltage and which products do not support it. Sometimes the board notes 12V but they work with 24V and sometimes not. Could you clarify which products support 24V and maybe put input voltage more clearly into descriptions? Thank You Y

KC868-AP JSON not valid

Posted by: simpl3x - 04-17-2025, 11:49 AM - Forum: KC868-AP / ADR - Replies (5)

Have KC868-AP

Code:
Board Model

KC868_AP

Software Version

v2.2.12

Build Date

Feb 28 2025 14:41:30

Serial Number

C82E18C85DFC

I try integrate it to Home Assistant over MQTT, but it not working.
I have this template:

Code:
mqtt:

  light:

  - name: 'KC868-AP-1-DIMM-1'

    unique_id: KC868-AP-1-DIMM-1

    schema: template

    state_topic: "KC868_AP/C82E18C85DFC/STATE"

    command_on_template: >

      {% if brightness is defined %}

      {"dac1":{"value":{{(brightness / 255  * 100) | int - 1}}}

      {% else %}

      {"dac1":{"value":255}}

      {% endif %}

    command_off_template: >

      {"dac1":{"value":0}}

    state_template: >

      {% if value_json.dac1.value == 0 %}

      off

      {% else %}

      on

      {% endif %}

    brightness_template: >

      {{ (value_json.dac1.value / 99 * 255) | int }}

when I change dimmer value in HA, message received on device and dimmer value is changed, but light state in HA still Unknown.
I try to check status JSON in linter and it have mistake:

Code:
{"input1":{"value":false},"input2":{"value":false},"input3":{"value":false},"input4":{"value":false},"input5":{"value":false},"input6":{"value":false},"input7":{"value":false},"input8":{"value":false},"input9":{"value":false},"input10":{"value":false},"input11":{"value":false},"input12":{"value":false},"input13":{"value":false},"input14":{"value":false},"input15":{"value":false},"input16":{"value":false},"input17":{"value":false},"input18":{"value":false},"output1":{"value":false},"output2":{"value":true},"dac1":{"value":0},"dac2":{"value":0},"dac3":{"value":0},"dac4":{"value":0},"dac5":{"value":0},"dac6":{"value":0},"dac7":{"value":0},"dac8":{"value":0},"dac9":{"value":0},"dac10":{"value":0},"dac11":{"value":0},"dac12":{"value":0},"dac13":{"value":0},"dac14":{"value":0},"dac15":{"value":0},"dac16":{"value":0},}

after "dac16":{"value":0}, has extra comma.
if I publish valid JSON in status topic without extra comma HA gets status of dimmer channel correct:

Code:
{"input1":{"value":false},"input2":{"value":false},"input3":{"value":false},"input4":{"value":false},"input5":{"value":false},"input6":{"value":false},"input7":{"value":false},"input8":{"value":false},"input9":{"value":false},"input10":{"value":false},"input11":{"value":false},"input12":{"value":false},"input13":{"value":false},"input14":{"value":false},"input15":{"value":false},"input16":{"value":false},"input17":{"value":false},"input18":{"value":false},"output1":{"value":false},"output2":{"value":true},"dac1":{"value":0},"dac2":{"value":0},"dac3":{"value":0},"dac4":{"value":0},"dac5":{"value":0},"dac6":{"value":0},"dac7":{"value":0},"dac8":{"value":0},"dac9":{"value":0},"dac10":{"value":0},"dac11":{"value":0},"dac12":{"value":0},"dac13":{"value":0},"dac14":{"value":0},"dac15":{"value":0},"dac16":{"value":0}}
