Lightbulb KC868-A2 + SIM7600 LTE + Home Assistant – Relays & Sensors over LTE?
Posted by: WestfieldGhost - 11-27-2025, 07:15 AM - Forum: KC868-A2 - Replies (3)

Hi everyone,

I’m working on a setup with a Kincony KC868-A2 and a SIM7600 LTE module and I want to connect it to Home Assistant over LTE only.
At the moment I’m using Tuya Cloud, because it seems to be the only solution that officially supports LTE with this board.
My goal is to:

• Control the relays from Home Assistant
• Read inputs and sensor values (ADC, 1-Wire, etc.) remotely via LTE

Current situation:

  • The device works fine in the Smart Life / Tuya app over LTE
  • It also appears in my Tuya Developer account
  • But in Home Assistant it shows as unsupported and I currently have no control at all
So my question is:
Is this device limited when used via Tuya Cloud, or has anyone managed to get full relay + sensor integration over LTE with it?
I’m not fixed on Tuya – it’s just the only LTE-supported method I’ve found so far.

If there is a better approach, I’m open to alternatives.

Has anyone here done this using:
• MQTT over LTE
• Or flashing the ESP32 with ESPHome or other custom firmware (without the original Kincony firmware)?

Important:
? I want to avoid any additional hardware or gateways.

Just the KC868-A2 + SIM7600 + LTE + Home Assistant.

Any ideas or real-world experience would really help.

Thanks in advance!

Information Automation lamps A16_V3+E16_V2 with traditional switch
Posted by: ArlokBR - 11-26-2025, 08:00 PM - Forum: KC868-A16v3 - Replies (8)

Hello,
After watching some videos on YouTube, I started my home lighting automation project.

Using the A16_V3 + E16_V2 hardware and KCS v3.15.0 software.

I'm using a traditional doorbell switch as input and I'm having trouble getting it to work.
   
I made the connection between A16_V3 and E16 as follows:
I suspect my problem is that I'm connecting to digital input 1 + GRD.
Where am I going wrong? How do I use it with a traditional switch?

  Recommended way to integrate into home assistant
Posted by: bernieke - 11-26-2025, 08:25 AM - Forum: F24 - Replies (1)

Hi,

Can you tell which is the recommended way to integrate with home assistant OS running on a raspberry pi 5? I'm looking for the most reliable method with a latency of less than 200ms to activate a relay.
* kcs firmware with mqtt over wifi
* esphome firmware with esphome over wifi
* usb (is this supported on home assistant OS?)
* bluetooth (is this supported as a client, and is it supported on home assistant OS?)
* ...?

Thank you,
Bernard

  DM16 output not turning off LED fully
Posted by: autolifetech - 11-25-2025, 08:23 AM - Forum: DM16 - Replies (26)

Hi,

I am using kincony DM16 as controller and Meanwell pwm 200 series for led driver to control my 24V LED strip

I am using the ESPhome code that was provided by you in the forum.
Issue now is I cannot turn the LED off fully when it is at 0%. When I short the wire to GND directly, the light can turn off, but when i use the channel, the light cannot off at 0%. How to solve this issue?

At this moment i cannot afford to buy new LED driver.

  Problem with A16 inputs 9-16
Posted by: jarekD - 11-23-2025, 07:25 PM - Forum: KC868-A16 - Replies (7)

On my A16, inputs 9-16 show all on, while nothing is physically connected.
I tested with a multimeter and there is +12V between GND and any input pin. It's the same on Inputs 1-8 btw, but they work just fine.

My device is connected to Home Assistant as ESPHome, below is the programmed YAML's relevant parts. I compared this with the recommended settings and it looks pretty much the same. Any clue what is wrong, or am I missing something in the config?

Code:
i2c:
  sda: 4
  scl: 5
  scan: true
  id: bus_a

pcf8574:
  - id: 'pcf8574_hub_out_1'  # for output channel 1-8
    address: 0x24
    pcf8575: false

  - id: 'pcf8574_hub_out_2'  # for output channel 9-16
    address: 0x25
    pcf8575: false

  - id: 'pcf8574_hub_in_1'  # for input channel 1-8
    address: 0x22
    pcf8575: false

  - id: 'pcf8574_hub_in_2'  # for input channel 9-16
    address: 0x21
    pcf8575: false
Code:
binary_sensor:
#skipped inputs 1-8, they work fine
  - platform: gpio
    name: ${input9_name}
    pin:
      pcf8574: pcf8574_hub_in_2
      number: 0
      mode: INPUT
      inverted: true

  - platform: gpio
    name: ${input10_name}
    pin:
      pcf8574: pcf8574_hub_in_2
      number: 1
      mode: INPUT
      inverted: true
# and so on for 11-16...
