Good morning,

I need to know how to enable the Modbus RS485 port in ESPHome for this board KC868-A16S.

I have this question because I need to control 6 fancoils Ideal Clima Ikaro with modbus protocol.

I attach pages of the service manual about modbus to understand if it is possible and how to do.

Why does it have so few dry-contact inputs? only 12 ...
old ESP32 AIO has 56

Is there any option to increase this and have external inputs available in one KCS v3 configuration (to use any input from outsite AIO Hybrid in AIO Hybrid IFTTT)?

Hello 

I am looking for some help with wiring my PIRs to the KC868-A16 as I am not getting any reading when motion is detected.

My PIRs have 6 terminals:

1. +12V
2. -12V
3. ALM
4. ALM
5. TAMPER
6. TAMPER

   

Power is supplied successfully via the +12V terminal.  The PIR was wired to the old board with one of the ALM terminals (left) and a TAMPER terminal. 

I have attempted to wire to a digital input on the KC868 and GND. On the PIR I tried the ALM and TAMPER terminals which did not work. And I also tried ALM (left) and ALM (right) terminals which also didn't work. I also read I needed to jumper the TAMPER terminals together but that did not work either.

If I short the blue and yellow wires connected to the digital input and GND I do get a reading, therefore the issue is on the PIR side.

Has anyone successfully wired a PIR like this? 

Thanks for your help in advance.

Hey!

I've been looking for the A2V3 board schematic, but could'nt find it on the forum or on the kincony webpage.
Is it publicly accessible? If so, could someone provide it for me?

Thanks!

Since the Inputs A1 to A4 have an internal pull up resistor the analog voltage should read 3V when the input is open. For some reason I am unable to read the voltage of a open input and it returns 0.075V.

Am I correct that the reading should read around 3V because of the internal Pull-up resistor?

The input config is:

sensor:
  - platform: adc
    pin: GPIO14
    name: "Analog Input A1"
    update_interval: 5s

What am I doing wrong?

KC868A8-V3 under ESPHome 2025.8.4

Hello,
Question: Can the 1-wire GPIOs be connected to the (with pull-up resistance on PCB):
S1:GPIO40
S2:GPIO13
S3:GPIO48
S4:GPIO14

Can other sensors be connected that do not require a pull-up resistor?
For example one:
- platform: ledc
  id: solar_pum_speed
  pin: GPIO40
  inverted: false

I'm unable to update firmware on my A32Pro.  

The flash downloader works fine, ESP32S3, develop, USB.  Port COM3 good.  Start.  Green bar grows, but finishes at 40% (between STOP and ERASE).

Tried holding DL button and turn on device.  No change.

Device now appears to be locked.  No LCD display, no network connection, no Wifi.

How do I restore to factory and or hard reset?
