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: 457)

bootloader.exe tool: 
  KC868 Controller Bootloader.zip (Size: 8.56 KB / Downloads: 728)
   
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

[17:49:15.467][D][modbus_controller:039]: Modbus command to device=2 register=0x100B no response received - removed from send queue [17:49:15.705][W][modbus_controller:284]: Duplicate modbus command found: type=0x4 address=4107 count=1 

any user tryed this wall pad?

I have 4 KC868-E16P-V2.3 with firmware version 2.2.14, after about one week, they go offline, no TUYA access(TUYA show Offline), and there is no Web-access. I have to power off/on to make them come online. It's random witch controller who goes offline, but all of them goes offline during one week or so.
They are powered by a MeanWell 12V 2.5A DIN-rail powersupply.

Hello

What is the suitable power supply voltage for KC868-16 - is the 13,5 V ok as well? Whats the minimum?

Hey there, 

some feedback and problems we detected on two N30 devices.

• Flash Guide with ESP Download Tool is incomplete, the guideline let you think to use the KCS bin file only. This is not correct, you will need more files (partion etc) to be able to flash.
  ESPHome Webflasher is the solution as it also accept the KCS Firmware File.
  

• EnergyConsumption in kWh seems to be not working in KCS Firmware (major bug!) Same problem as in Link
  

• Voltage Calibration is not possible in KCS Firmware
  
  
• Are negative power readings possible? 
  

• If yes, can there be an independent energy calculation per input for positive/negative consumption readings?
  

Hello,
I am looking for a KinCony solution for a professional home lighting automation setup.
Requirements:

• 16-channel relay controller (220V AC)
  
• Use of standard mechanical wall switches (2-way / 3-way)
  
• Real light state feedback (Home Assistant must always know ON/OFF state, even when switched manually)
  
• Mandatory Home Assistant integration (MQTT / ESPHome / native)
  
• Minimal GPIO usage (no one-GPIO-per-switch design)
  

1. Which KinCony model(s) do you recommend?
   
2. How is state feedback implemented (dry contact, relay feedback, current sensing, etc.)?
   
3. Do you have wiring diagrams or documentation for this scenario?

The DO1 output physically shows a high state. After uploading new software, when logging in directly to the controller, the inputs and outputs are disabled, but DO1 physically remains on all the time. I have no idea what is causing this. I haven’t connected any relays to the outputs yet.
