Smart Home Automation Forum

Dear Kincony-Team,
 
I'm currently looking for a suitable circuit board to realize a new project. At my search I found your website and some boards that could be the right one (for example the KC868-AI) but I’m not sure which one is the right one. Can you possibly tell me if the KC868-AI is the right one respectively which of your boards would be suitable?
 
I have 13 windows in my house and every window has an sensor for the status (open, closed and tilted). I want to integrate these sensors in my already existing Home Assistant installation. I think the integration via ESP could be one solution.
Here the information about the sensors:
 

• 7-wire cable
  • 2 wires for the sabotage loop / sabotage line
    
  • 2 wires for the signaling contact (generally open/closed)
    
  • 3 wires for the open/tilted state (common "ground")
    

 
According to the instructions, there are also the following technical data:

• General:
  • Switch voltage max. 48V DC
    
  • Contact resistance max. 150mOhm
    
• Surveillance:
  • Switching current max. 0.5A
    
  • Transport current max. 1.0A
    
  • Switch performance max. 10W pure ohmic load
    
• or for the tilt status query:
  • Switching current max. 0.25A
    
  • Transport current max. 1.2A
    
  • Switch performance max. 3W pure ohmic load
    

 
Attached you can find an extrude of the installation instructions.
 
It would be nice if you could tell me if the KC868-AI is suitable. If it is not, which of your boards would be suitable? Is there eventually already a program / yaml for ESP or Home Assistant is existing?
 
Thank you in advance.

KC868-AI have 48 channel digital input ports. 0V means ON, 12-24v DC means OFF. so you need to confirm your switch wire's voltage level. if only use by dry contact signal, it's no problem.

here is yaml file for KC868-AI , it can directly use in home assistant:

Sorry, I'm no electrician. So this is not so easy for me.
Is it possible to use KCOM of the KC848-AI for the wire to the sensor and the inputs for the wire from sensor to board? Or did I need an separate power source instead of KCOM?
Like it is written here:

most window sensor have two wires, not need power supply. two wire connect to KCOM and INPUT for KC868-AI, very easy.

Thank you for your confirmation. I think I will give it a try and order the board.

But two last Questions: Can you give me information what is present at KCOM (voltage / current)? And do you have an manual for the board?

ok

KCOM just GND. digital input short with GND means "trigger".
here is our firmware details: https://www.kincony.com/guide
i think you can using KC868-AI board, when have questions post at here is better do understand.

@admin

Now I want to install the board and integrate it in my Home Assistant. The problem is, ESP32 is a complete new world for me and I'm not sure what the next steps are / the right order is.

Is the following doing correct?

1) Connect the Board with the PC
2) Install the sketch from https://www.kincony.com/forum/showthread.php?tid=2017 via https://web.esphome.io/
    -> Before I need to modify the Home Assistent API because they have changed it. But where do I get the API-Key?
    -> Where do I set my Wifi access data?
3) Add the board via ESP integration to Home Assistant

Thank you in advance!

1. install home assistant on your server.
2. install ESPHome addon on home assistant
3. create controller in ESPHome, just copy our yaml file
4. download firmware by USB-Serial port.
