  Power supply via UPS, leakage sensor, other UART devices
Posted by: gasinskiy - 09-17-2023, 10:56 PM - Forum: KC868-A series and Uair Smart Controller - Replies (3)

1. Can I supply voltage to the KC868-A8S module from an uninterruptible power supply, which produces 13.8 V when powered from the mains. And what is the lower voltage threshold at which the board will stop working?

2. Can I connect any other UART device instead of the telephone module? For example PZEM-004T?

3. Can I connect the Neptune SV005 leak sensor this way? It has 12 V, in the case of a UPS 13.8 V voltage between ground and output, when triggered 0V. 

Thank you!

  KC868-A8M and PCF857x error
Posted by: Madjo - 09-17-2023, 05:02 PM - Forum: KC868-A8M - Replies (8)

Hello.
I have new board KC868-A8M v1.1 from Aliexpress.
Firmware: KCS_KC868_A8M_V2.1.4.bin

There is no reaction to the inputs in the web interface, mqtt and others. When the outputs are turned on in the web interface, the LEDs on the board do not light up.

Not working (from first sartup) inputs and otuputs. Debug show:
I (2981) RF: Start RF receiver
E (3982) pcf857x: pcf_0 read error!
E (3983) pcf857x: pcf_0 write error!
I (3987) pcf857x: pcf857x init.

I have verified the SLA and SDA lines - they are alive. Voltage on PCF - 3,2V

I2C scanner found PCF module:
I2C scanner. Scanning ...
Found address: 34 (0x22)
Found address: 36 (0x24)
Found 2 device(s).

Sketch [Arduino source code for KC868-A8M]-03 INPUT} with Serial.print ("In 1: "); - working, but LED on OUT don't light. I see a reaction to a short circuit in the terminal, with the modified code

Sketch [Arduino source code for KC868-A8M]-05 OUTPUT - not working. Not LED light on out.

In library PCF8574.h for 0x24 sketch print "Init pcf8574...KO". Not ''OK"

Exclamation KC868-A8 Ethernet Problem
Posted by: msinfo - 09-16-2023, 03:32 PM - Forum: KC868-A8 - Replies (15)

Hello, i have a KC868-A8 Board connected with ethernet cable but the port suddenly stopped working. The port indicators are both flashing and the board keeps restating every 15min because it searches for a ethernet connection. I use it with ESPhome and home assistant. If i re-flash the esp32 with a WIFI configuration everything works but when i try to use the Ethernet port i get an error and it goes offline in esphome. (Component ethernet was marked as failed.)
Here is my code -

ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0

manual_ip:
  static_ip: 192.168.1.154
  gateway: 192.168.1.1
  subnet: 255.255.255.0

Any ideas on how to fix this ?

I flashed A16 with ESPHome and all sensors are ON, they don't change state when I change the input.

  m16v2 - Unable to read voltages
Posted by: sure - 09-13-2023, 04:59 PM - Forum: KC868-M16 / M1 / MB / M30 - Replies (10)

I've received an m16v2 today.

I've have flashed it with esphome with the provided yaml file you've provided. After that, the onboard LCD screen began working.

I've included the zmpt101b/ folder and have confirmed that this code is getting included in and compiled in the binary firmware.

Unfortunately, I'm not able to get any voltage readings from the zmpt101b chips. I've tried voltage_1 & voltage_3. Neither return any values.

I'm confirming that nothing is sent not only via the LCD display (which defaults to voltage_1), but also in Home Assistant where I've set up the device to log the data.

Everything else appears to be working fine, just the voltage is not showing up.

Any idea what needs to be done to get the voltage sensors working correctly?
