Hello,

In the pin definition for the T16M, it shows the Eprom on the I2c bus.

How can we use the Eprom in ESPHome, and what is the size of the storage?


Thanks, Rob

Hi,
Finally I've received the kc868-a16 unit and got it working. Or at least somewhat working. I've flashed the kcs_kc868_a16_v2.2.18 firmware and it seems to be working. The board boots up and I can connect to it through the browser but I can't control it.
In the monitor tab there is the output section and I can click on ALL ON or ALL OFF and the squares go green or gray but the board doesn't do anything. The led indicators don't turn on and checking with a multimeter there isn't anything opening or closing.
I've tried shorting the digital inputs but that doesn't do anything either.

Am I missing something? Do I need to set up anything else? 

Thanks!

Hello,

I have a T16M (ESPHome), and I need to connect 4 Wiegand keypads (8 GPIO required).  There are 7 GPIO, and 2 RS485 available.

Are the RS485 connections just a UART, and can be used for a Wiegand D0/D1 ?

------

I have noticed in your videos on Wiegand that you use the UART rx/tx connections on the example boards.
Is that because they are 5v logic, and are required to connect the 5V D0/D1 from the Wiegand keypad?

I assume the ESP32 will be damaged if I connect the D0/D1 to the GPIO connections of an ESP32 based board like the T16M?

Thank you.

Rob

Hello,

My KC868-COLB is no longer visible on my network,

The UDP Blue LED and Server Yellow LED are flashing on and off together for approx 2 sec on, 2 sec off.

I have tried pressing and holding the Ethernet M button as described in the user guide but the LED's are not lighting up to switch modes. Nothing happens when i hold this button in.

Is there a way to do a reset on this board?

My tiny alarm seems to be transmitting a wifi signal (AP?)  "SmartLife-C886" how do i disable that?

Hello,
I started working over new home automation project and I bought Server 16 with raspberry pi & nodered. Board is working fine with rs485 sensors, but I'm planning to use relays to control electric circuits and I have two major difficulties :
1) by default I want to have circuits off (NC), I changed settings of all relays in nodered to invert switches, but when board starts it triggers all relays for a moment ON and after moment all goes to OFF. It means that all connected electric equipment will start for a less a second - this is very unwanted behaviour, how to avoid that?
2) I'm planning to use digital inputs to control relays with momentary buttons, but input seams to be connected with relays and input has to be shorted with GND all the time, how to change that, so relay will be toggled wen button is pushed for a moment?  I don't want to use bistable buttons, as relay will be connected with nodered and homeassistant in parallel and wall buttons will have different state than circuit 

Beet regards 
Podlak

1. fixed bug: update energy data to home assistant by MQTT.

1. fixed bug for energy data and power factor.
you can download by bootloader.exe tool by RS485.
ARM BIN file download:

  N10203060_KU_V20_251231.zip (Size: 13.11 KB / Downloads: 148)

bootloader.exe tool: 
  KC868 Controller Bootloader.zip (Size: 8.56 KB / Downloads: 130)
   
1. set baud rate=38400bps.
2. open com port.
3. power on Nx board, during LED fast blink when the "bootloader Detect" button right now. Then board will go to bootloader mode.
4. open BIN file
5. press "Download" button, begin download firmware, after finished, press "Run" button, ARM CPU begin work.
   

Hi, 

in the modbus specifiaction from N30 it is mentioned that Energy Sensor from BL0910 has a resolution of 1kWh only.

Is there any way to get a more accurat reading? For power circuits with low consumption it is misleading to see 0kWh consumption on end of day.

Does the BL0910 has a possibility to report for example 0,1kWh as resolution for Energy Consumption?

Thank you.

Hello
I need help with setup wallpad using modbus:
google drive with manual:
https://drive.google.com/drive/folders/1...drive_link

i have some errors, code from ai

any user tryed this wall pad?
