  Analog Input NTC
Posted by: Gazura36 - 10-22-2025, 09:22 AM - Forum: KC868-A16 - Replies (3)

Hello,
I’m trying to connect a 10 kΩ NTC temperature sensor to my KC868-A16 board.
Unfortunately, I don’t get any readings at all.
Which GPIO pins are actually used for the analog inputs?
I used the example code from this forum, but I don’t get any plausible values on any pin.
I also tested by connecting each pin to GND to rule out a sensor issue, but the readings still don’t change.
I’m stuck now — what is the correct code to read the analog inputs properly?
Thanks in advance for your help!

  IIC Not working
Posted by: Eggman - 10-22-2025, 08:16 AM - Forum: KC868-A series and Uair Smart Controller - Replies (4)

All of a sudden none of my sketches using IIC work on my boards.  In the past I have used the sketch below to scan the IIC bus,  I would expect to see several devices detected by default.  However it just says " "No I2C devices found".  I have tested this on several K868 boards.  How could this happen all of a sudden?  It is due to a change in the Arduino IDE environment?  Is it possible that something has changed withing Wire.h?

Many thanks for any assistance.

Photo receive data from switch by RS485 and control output of KC868-A16
Posted by: edg72022 - 10-21-2025, 08:04 PM - Forum: KC868-A16 - Replies (3)

I try to find the way to control Output of KC868-A16.

I found the way to send information from KC868 but not on the other way.

Below a print screen of the way I used to do it.
and the link of data information

  MODBUS RTU comunication KC868 wich Siemens S1200 RS485
Posted by: naurismaculskis - 10-20-2025, 08:06 PM - Forum: KC868-A6 - Replies (3)

Hello. I have siemens S1200 PLC and I try to comunicate over Modbus RTU and can't get KC868-A6 comunicate over Modbus. Maybe someone has been seting up MB master and has some example in TIA portal? Or maybe someone knows MB Master Data addr?

I was trying to find register addres in  "KC868-A series board protocol – Modbus"  file but there it says that register is 0000 which does not work. 

I added MODBUS file in attacment for  KC868 series.

  a8v3 - RXTX and 4 pulse counters
Posted by: rockyhopper - 10-18-2025, 04:30 PM - Forum: KC868-A8v3 - Replies (1)

Hello,

I plan to buy a8v3 and use it with ESPhome.

But, I would need:
- RXTX (https://esphome.io/components/uart/#uart) ideally on external connector
- 4 Pulse Counters (PCNT, https://esphome.io/components/sensor/pulse_counter/) on external connector

Could you confirm that:
- for RXTX, I can re-assign pins used for Analog Input (AI-1 and AI-2) and map RXTX on it.
  Would I lost any other feature (than ADS) from a8v3 in that case (I think that ESP32-S3 is limited to 2 end-user RXTX)? 
  If that's not possible, can I directly re-use the RS485 connector (for my RXTX pins) as I don't plan to use RS485.

- for my 4 pulse counters, can I re-use the 4 "one-wire with pull-up" (S1 to S4)?
  (I plan to add 1-wire over i2c -- DS2484 to support 1-wire sensors, then I don't need those S1-S4 pins).

Thanks in advance for your support.

Lightbulb Centralized vs distributed control boards
Posted by: TonyB - 10-16-2025, 12:47 PM - Forum: DIY Project - Replies (3)

Hi everyone, I'm designing a new electrical system with Home Assistant integration for a 120 m² apartment with 8 rooms. I’m currently trying to decide on the best approach for the control boards.
Would you recommend using a single central control board to manage all lights, sockets, and other devices, or would it be better to install multiple smaller boards distributed around the apartment to keep wiring shorter and more efficient?

Any suggestions or examples from similar installations would be really appreciated!
Thanks in advance for your help.
