Hi Have a question about a how best to connect a signal that is about 1.2 - 2 volt. 
I presume I can not use the dry contact input 1 - 8 a they are 12v ?


Is there a way to get the board to detect a small 1.2 volt signal
Can I use inputs S1 - S4?

Thanks

I request a KC868-A4 equipment for education. I work for a school in Spain and we want to teach our students microcontroller programming and basic concepts of electricity and electronics.

Hi, I have the KC868-H32B board. I'm interested in how: can I connect the ZP13 Smoke Gas Sensor (like 7 sensors to one input slot)


All information about the module is provided here: https://www.winsen-sensor.com/d/files/manual/zp13.pdf
For this module's physical interface: XH2.54-4P terminal socket.


If this module is not compatible, could you recommend another one? But I need a module only.



Thx for your time and help who can replay me

Hi,

Is it possible to connect a 2-wire PT1000 sensor to the KC868-A8 (by using ADC)?
I connected my PT1000 to A1 and GND, but i get these readings in esphome:

[12:20:21][D][sensor:094]: 'Temperature_4': Sending state 0.14200 V with 2 decimals of accuracy
[12:20:22][D][sensor:094]: 'Temperature_3': Sending state 0.14200 V with 2 decimals of accuracy

with this setup:
sensor:
  - platform: dallas
    address: 0x453c3ee381b36028
    name: "Temperature_1"
    id: Temperature_1
   
  - platform: dallas
    address: 0x783ce104577f4c28
    name: "Temperature_2"
    id: Temperature_2    
  - platform: adc
    pin: 34
    name: "Temperature_3"
    update_interval: 5s
    attenuation: 11db
  - platform: adc
    pin: 35
    name: "Temperature_4"
    update_interval: 5s
    attenuation: 11db  



I found this picture bellow, do I have to add 12v to the sensor? How do I do that if my PT1000 sensor has 2 wires? 

Hi, I'm trying to connect the DHT21 sensor to the KC868 - A4S board but the firmware doesn't work. who can help me?

Hello,

I have ordered a wall switch panel recently, however the the metal frame size is 86mm x 86mm and in EU the frame size is 73mm x 73mm.

It makes impossible to to put more that one switch next to each other. I added a photo of the EU electric round outlet boxes installed to a wall.

Do you have EU size frames or e a 3d model of the metal frame, I would make it smaller and print it on a 3d printer?

Thank you in advance!

   

Hello engineer

We need  to restart the kc868-server daily  at an exact time to save fresh system 

So How can we do that in Home Assistant?

Hello engineer

I want to config Kc868-server to home Assistant by Esp

So can you give me Config file .Yamal

Hello ingneer 

I have KC868-A128 esp

I used esp protocol 

But we need to make interlock fo curtains and shutters.. 
 Can you give me the code for this operation

KinCony DO8 is PCF8574 IO Expansion i2c relay board. extend 8 channel 10A relay. manual control buttons on board can control relay ON/OFF directly without any software. manual control buttons control relay’s coin physically. A0,A1,A2 PCF8574 i2c address can set by DIP switch. DO8 support install on DIN RAIL.

it's open source board.

it support integrate to home assistant by ESPHome.
