We have developed the first DIY product for smart home enthusiasts to cultivate everyone’s interest in electronic technology. “KC101” is 4 channels universal WiFi wireless smart switch with RF 433MHz module, it’s a DIY kit for DIYer. it for your smart home system to remotely and automatically turn ON/OFF home appliances and electronic devices by mobile phone APP. We have opened schematic, components list and all details. Also have made the video tour step by step help you easy to DIY make it.

Hello!

I install kc868 meter 4py to my distribution box and i connect it to my COLB with RS485 port.
I managed to get the readings  to the smart board controller software.

How to connect it with home assistant to appear the data?

Hi there!
 Your products are very interesting and quite comfortable in use but finding technical data about product is utterly frustrating
   Could you make it clear, what pins on mcu are corresponded to the upper side? I mean where are the temperature sensors pins on pcb? There is not the place which is the only where I can find all the data about product. I have to get through all your webite, to find any info pice by pice: picture with pinout is on home page, schematic diagramm is on absolutely different page, pins defines is on the forum. And all of this info conflicts to each other. 
 

  where is the temp sensor inputs on the picture? Why  in the description   it's sad there are only two analog inputs, but on the picture and pcb i can see 4 ones? What are the io-1 and  io-2 on the picture of the board? Are they temp sensor input? ok, but why they have absolutely different name wich aren't somewhere else? why is all the info so inconsistent?

  And why dont't you place all the information related to product the right on the product page?

We have designed new version KC868-E16 V2 extend relay module. Now every relay have COM, NO, NC port and use by metal manual control switch buttons.

Hi Kincony,
I was buy K868-A16 board. rev 1.5
I need an Arduino source to communicate with the Ethernet port.
Tasmato or Home assistant is not helpful.
Is there an example source for socket communication with the LAN port? (i don't use wifi..because of the reliability..)
Please guide me.

thank you,

Hi
Can I use AT32F415RBT7 MCU Chip with my KC868-H8 board if I want to have MQTT support with new firmware in my board?

Hello admin,

thanks a lot for these really nice PCB, which allow lot of powerful projects!

I've checked the circuits of KC868-A4 (and other KC868-versions) and you are right, the direct GPIO-communication is easier to handle for Arduino-newbies than bus-connected parts.
Nevertheless I found out some optimization for KC868-A4-hardware. Maybe you can use it for an future hw-update.

• cancel RS232 (saves lot of space + USB-C is sufficient for controlling the PCB directly)
  
• change IRD/IRS & 433MT/433MR to 1x I2C-bus (2x ordinary 4-Pin-connectors, i.e. for display & other I2C-parts)
  
• add a connector for an accurate working I2C-DS3231 RTC-modul
  
• make the 2x 0-10V-DAC jumperable also to 2x 0-5V (to control 0-5V-devices)
  
• a relay OR mosfet option would be great (or to get only 1 PCB => 2x relay + 2x mosfet)
  
• ESP32 on a socket => stackable ESP32 (allows different ESP32-versions (i.e. with external antenna) and change of controller, if there is a problem). I know it's more expensive, but fast changing a small ESP32 is a superior feature. I.e. a company can send only the small ESP32-modul to consumer, if somthing went wrong.
  

Hi KinCony IoT,

Is it possible to reach the WebUI over Wifi in STA mode to manage the relays?
I can reach the webUI over LAN port.
Both Ethernet and Wifi are set to TCP-Server.
I was able to configure Wifi in STA mode and connect to my Wifi router. Then I disconnect the wired LAN port, but when I try to connect to the relay over the Wifi IP it doesn't give back the Relay Web UI, but the Wifi ESP32 config UI.
I would like to use HTTP commands over Wifi. Is it possible?
