Question: According to the description, the KC868-A8v3 board has an ESP32-S3-WROOM-1U (N16R8) installed, right? 
According to the datasheet, it is built around the ESP32-S3 series of SoCs, Xtensa® dual-core 32-bit LX7 microprocessor, flash up to 16 MB, 
and PSRAM up to 16 MB, so 16 MB is installed! 
Do I need to specify this in the configuration?

esp32:
 board: esp32dev
 flash_size: 16MB
 framework:
   type: esp-idf

esp32:
  board: esp32-s3-devkitc-1
  framework:
    type: arduino

Hello.

I bought N30. Download and write KCS v3.15.0 firmware for N30.

Some observations.

After changing Current Factor to take effect Reset ARM CPU button must be pressed.
Current Factor:
In youtube video Current Factor mean:
Value*CurrentFactor=desired value.

It's not TRUE. It works like:
Value/CurrentFactor=desired value.



I use CT 3000/1 and need to correct values. N30 gives 0.12A instead real value is about 0.17A

Next one. I connect to N2L2 to power source.



And I have Power Factor is 0.00. Is it correct?
Voltage and 228.9Frequency are shown correctly.

Best wishes.

Hi,

I wonder if there is any board that fits my needs...

I'm driving lights & blinds using 24VDC relays and all over the house I have buttons(lights) or up/down buttons(blinds). All this buttons have 24VDC and are connected to main junction box that has all this relays which drive 240VAC lights/blinds.

I want board that has single pin(so I need to connect just 1 wire, per light) that reads that wire 24V via optocoupler at same time board has on same pin MOSFET that can drive that relay.

So idea is, that I can detect when user is pressing some button and they drive lights, but at same time I can drive lights and in both cases I want to read this signals.

Does such board exist?
I already have KC868-A16 but as far as understand I need additional optocoupler, since I'm not allowed to connect 24VDC on input, so I need external optocoupler to simulate dry contact on KC868-A16 and makes everything ugly with additional optocoupler and 2 wires per relay.

Thanks,
David

Hello, 
I have 3x a16 added to HA, but when HA is not availble,i have restart from time to time.
I added api, reboot_timeout 0, but not help.
Now i see on debug no client connected, rebooting.
Is it any sollution to fix restarts when a16 with esphome can working stand alone?
Mayby connect a16 together? Then any a16 will be as serwer and client?
I made light shaft and any reboot reset relays..
Need solution,please.
Regards

I would like to use the discoverable entity for homeassistant , is it possible that the 485 interface HAv2 can also be adopted this way into home assistant?

Hello, can I read and display an "RS485 Temperature and Humidity Sensor Modbus RTU Use By SHT30" using KCS v3 (3.15.0)?
Under Sensors “Type,” I can only set TR (RS485) and TS (RS485).

Prezada Equipe de Suporte Técnico da KinCony,
Estou usando a placa de automação residencial inteligente KC868-A6 V1 4SP .
Preciso saber se é possível usar o controle de fluxo de hardware RTS/CTS (Request To Send / Clear To Send) nas portas seriais RS232 e/ou RS485 integradas .

• Em caso afirmativo: Poderia especificar quais pinos da placa estão atribuídos aos sinais RTS e CTS para as interfaces RS232 e/ou RS485?
  
• Caso a resposta seja NÃO: Você poderia recomendar um modelo alternativo de placa KinCony que suporte o controle de fluxo de hardware RTS/CTS por meio de sua interface RS232?
  

Muito obrigado,

Hello,
Is there an MQTT command to update the D16 dimmer's stored brightness memory value WITHOUT actually turning on the dimmer?

Current behavior:

• Send
  
  Code:

  {"dimmer1": {"value": 50}}
  → Light turns on at 50%
  
• Send
  
  Code:

  {"dimmer1": {"value": 0}}
  → Light turns off, hardware remembers 50%
  
• Physical button press → Light restores to 50%
  

• While dimmer is OFF, update the stored memory to a different value (e.g., 30%)
  
• So next physical button press turns on at 30%, not 50%
  
• Without the light briefly flashing on
