Use case - possible?

Posted by: CG25 - 03-16-2025, 07:54 AM - Forum: KC868-A series and Uair Smart Controller - Replies (7)

	Can I use the product for this use case: - recieve RS232 signals from external source for open/close of the relay - attach OLED screen and configure display myself - read signal from distance sensor (ultrasonic analog / laser digital) - read temperature to adjust ultrasonic measurement (hot/cold air) - send measurements to server via HTTPS over LAN

multiple power distribution boxes

Posted by: daniel45 - 03-15-2025, 10:54 AM - Forum: DIY Project - Replies (1)

Hi all,

Thanks to join your forum.

I'm preparing a home installation based on HOME ASSISTANT using KC868 with rapsberry.

I need multiple power distribution boxes in different buildings based on :

One main power box ( with KC868)
3 remote connection power boxes. (with relays and analog input )

So, could you help me on which communication hardware and protocol I can use ? ( cables CAT 6 are dispached between each boxes.).

Hope my explaination are clear . Big Grin

Great thanks

Daniel

Inquiry About Sensor Compatibility with the Board

Posted by: engrezk - 03-15-2025, 07:06 AM - Forum: DIY Project - Replies (1)

The water level sensor is malfunctioning and has three terminals: two for 12 volts (one positive and one negative) and one for data. The new locally available sensor, however, has only two terminals: one for 12 volts positive and one for the data point. I will attach pictures for reference. My question is: should I connect the positive terminal to the 12-volt power source and the data terminal to the data point on the board? Is this the correct approach?

Relays on ESPHome not working

Hey everyone!!
I just configure my brand new KC868-A16 REV 1.6 on EspHome with this code:

Code:
esphome:

  name: calefaccion-central

  friendly_name: Calefaccion Central

esp32:

  board: esp32dev

  # Enable fallback hotspot (captive portal) in case wifi connection fails

  ap:

    ssid: "Calefaccion-Central"

    id: sw_caldera #1

    pin:

      pcf8574: outputs_1_8

      number: 0

      mode: OUTPUT

      inverted: true

I erase all the unecesary code.

The board seams to work ok, but I cant get the realys to work.
Here is the log from ESPHome:

KC868-AG board type

Posted by: powerup - 03-12-2025, 01:33 AM - Forum: KC868-AG / AG Pro / AG8 / Z1 - Replies (3)

	Hi, i am programming myself the KC868-AG, i bought 2 units. 1 of them died after 1-2hrs, the other unit is working fine. The first one is giving USB device not recognized. Same cable is working fine for the other device. Q1: what chip do I choose for this device. Q2: what is the memory limit of this device, does it have enough space for OTA updates and save many RF signals? Thank you.
