  Hardware issues
Posted by: ogo - 11-29-2024, 09:54 AM - Forum: KC868-A8 - Replies (1)

Hello,

I bought a KC868-A8 a while ago that I've been using to test things and learn. Today I finally wanted to configure it properly to controls some lights. I have two issues

  1. Output 3 and 4 don't work: when I enable the outputs via home assistant or KCS, the LEDs for the outputs don't turn on, and I can't hear the click on the relay.
  2. When activating output 8, outputs 5, 6, and 7 are also activated: When I activate output 8 via home assistant or KCS, the LEDs of outputs 5, 6, 7, 8 turn on, even though those relays aren't active.

Things I've done so far:
  • Remove everything from home assistant and install it again
  • Disconnect everything from the board
  • Flashed KCS instead of ESPHome
  • Factory reset using KCS
  • Flashed ESPHome again

Nothing seems to fix it, so I can only think it's a hardware issue, not software. The board version is 1.6, and it also has a 433 MHz receiver/transmitter.

Any ideas?

  Replacing KCS868-E8 relays with 24V
Posted by: Revinor - 11-29-2024, 09:24 AM - Forum: Development - Replies (1)

I'm using 24V output from KCS868-B16M for controlling few devices. At same time, I would like to use some of these outputs to drive 230VAC. Can I just replace all relays on KCS868-E8 with G2R-1A-E-24VDC, connect 24V supply and 24V outputs from KCS868-B16M there and everything will work? Or are there some parts there which won't work with 24V even if all relays are replaced?

* 1. When the ESP32 receives a heartbeat packet (55 AA 00 00 00 00 FF),
*    it sends a heartbeat response (55 AA 03 00 00 01 00 03).
* 2. When the ESP32 receives a product information request (55 AA 00 01 00 00 00),
*    it sends a product information response (55 AA 03 01 ...).
* 3. When the ESP32 receives a work mode request (55 AA 00 02 00 00 01),
*    it sends a work mode response (55 AA 03 02 00 03 10 1C 14 47).
* 4. When the ESP32 receives a network status request (55 AA 00 03 00 01 00 03),
*    it sends a network status response (55 AA 03 03 00 00 05).
* 5. Subsequent heartbeat packets (55 AA 00 00 00 00 FF) are responded to with
