Good morning,

I wanted to know which sensors can be used for the analog inputs of COL. from the textbook it says 0-5V, but often the sensors are resistive.

I would need to monitor a temperature from 0 to 100 degrees.

thank you

1. install rpiboot.exe for Raspberry Pi Compute Module 4 eMMC USB driver.
    For Windows Installer
    For those who just want to enable the Compute Module eMMC as a mass storage device under Windows, the stand-alone installer is the recommended option.

        1. Please ensure you are not writing to any USB devices whilst the installer is running.
        2. Download and run the Windows installer to install the drivers and boot tool.

  rpiboot_setup.zip (Size: 9.9 MB / Downloads: 761)
        3. Plug your host PC USB into the KC868-Server USB port, making sure you have setup the board as described above.
        4. Apply power to the board; Windows should now find the hardware and install the driver.
        5. Once the driver installation is complete, run the RPiBoot.exe tool that was previously installed.
        6. After a few seconds, the Compute Module eMMC will pop up under Windows as a disk (USB mass storage device).

2. install home assistant OS to Raspberry Pi Compute Module 4's eMMC.

    Write the image to KC868-Server. if CM4 have eMMC, not need insert SD card. if CM4 without eMMC, Attach the Home Assistant boot media (SD card) to your computer or by USB card reader.

    1. Download and start Balena Etcher tool.
    2. Download home assistant for Raspberry Pi image:  https://github.com/home-assistant/operat...7.4.img.xz and unzip it.

    3. Select “Flash from file”


    4.  “Select target”



    5. Select the SD card or eMMC driver you want to use for your Raspberry Pi


    6. Click on “Flash!” to start writing the image

    7. When Balena Etcher is finished writing the image you will get this confirmation


START UP YOUR KC868-Server
    1. Insert the boot media (SD card) you just created. if use eMMC , skip this step.
    2. Attach an Ethernet cable for network.
    3. Attach the power cable.
    4. In the browser of your Desktop system, within a few minutes you will be able to reach your new Home Assistant on homeassistant.local:8123.

    If you are running an older Windows version or have a stricter network configuration, you might need to access Home Assistant at homeassistant:8123 or http://X.X.X.X:8123 (replace X.X.X.X with your KC868-Server's IP address).
    With the Home Assistant Operating System installed and accessible you can continue with onboarding.

Hello

Today I have powered off the server which runs Home Assistant and Mosquitto Broker for maintenance. I have several wall switches connected to Dimmer D8 and the Dimmer D8 work mode is set to MQTT and switcher workmode to 1 key. I have observed that without an active MQTT broker all the wall switches are unresponsive. Have to press several times to turn on/off the lights. 
After the MQTT broker gets online again the wall switches are working fine again. 

Could you please take a look to this problem.

Thank you.

Hi

What is the exact procedure to flash that device ? and please don't send me your useless youtube videos !! I have applied 12V on board (board starts well) I plugged the USB cable between my computer or my Home assistant system and the board but ESPHome never succeeds to communicate through the USB port to flash the board  Got no problem to flash the K868-AG and the K868-Uair but not that device..

Here is my basic code used for now:

If you want your home become smart, many people don't know how to design and choose products. This article / video will explain what to consider and how to choose KinCony products before preparing to build a smart home.

1: Function
2: Reliability
3: Expansibility
4: Select products

1. function

    a. What load needs to be controlled?
    b. What software platforms need to be used?
    c. Smart control your device in your home or outside of home?

        a.Lighting, curtains, shutters, air conditioners, televisions, multimedia players, LED strip, cameras, security systems, environmental detector, valves, garage doors, etc.

            Select the corresponding hardware products according to the equipment to be controlled.

        b.mobile phone? computer? PAD? voice?

            You can use kincony's own software or home assistant software.

        c.Only need to be used at home? Or do you need remote control?

            You can use kincony's own software or home assistant software.

2. reliability

    a. Whether can pull new cable? If there is no way to pull the wire, only wireless products can be used. The core control system strongly recommends wired products, because the stability of wired solution is better than that of wireless solution.

    b. It is suggested to use the solution of separation of controller + relay driving unit. Because of the separation design of High voltage circuit and low voltage circuit, it has good anti-interference, but takes up more space. However, if the relay is damaged in furture, it can be easily replaced by yourself.

    c. For the core control system, we strongly recommend the wired solution. If use sensor products, we should also choose wired products as far as possible. Due to limited conditions, we can choose wireless products.

    d. For the smart home system, we hope that there are manually controlled switches at the same time. Even if there is no Internet or LAN, your router is damaged and your controller is damaged, the manual switch should still be able to turn on / off those important devices, so as not to affect the daily work. This is a very important point! No system is guaranteed to be foolproof. Add the KC868-E16 or KC868-E8 can do this.

3. Expansibility

    a. Selection of communication interface: Ethernet, WiFi, RS485, RS232, Bluetooth

        It is recommended to use Ethernet and RS485 wired communication solution products with long distance
        RS232 is about 12 meters
        WiFi as the last option

    b. What are the communication protocols: mqtt, HTTP, MODBUS, TCP private protocol

        Mqtt, HTTP and TCP private protocol are ways to integrate hardware products into third-party platforms based on network way.
        Modbus is a way to integrate hardware products into a third-party platform using RS485 bus
        It is recommended to use Ethernet to connect all hardware devices to the home network, which is more flexible and convenient.

    c. Firmware upgrade: according to different hardware products, firmware upgrade through network, RS232 and RS485, obtain the latest functions and fix some bugs.

4. Select products

    a. Interface definition
    b. Supported software
    c. Shell
    d. Match the available products of different models according to the load control mode
    e. Automatic control solution

        a. The core controller is distinguished according to the interface definition:

            KC868-Server / KC868-H32BS: connect with wall switch button directly, support RS485 modbus, support remote control, MOSFET output, Ethernet and WiFi can work at the same time. MOSFET output need add extend relay module (KC868-E16 / KC868-E8) or DC contactor for loads.

            KC868-HxB series: need add switch terminal board for wall switch panel, without RS485, with relay inside. Ethernet and WiFi can work at the same time.

            KC868-A series: some models of MOSFET output, some models of relay output, Ethernet and WiFi can’t work at the same time, you can use ethernet or use WiFi. MOSFET output need add extend relay module (KC868-E16 / KC868-E8) or DC contactor for loads.

        b. Supporting software:

            KC868-Server/KC868-H32BS/KC868-HxB series:

            1. KinCony Smart Home App (need internet)
            2. KBOX App (without internet)
            3. PC software (without internet)
            4. Open communication protocol, provide software demo source code, but CPU program is not open source.

            KC868-A series:

            1.Support for open source firmware -- Tasmota
            2.You can write programs using ESPHome tool
            3.You can write programs using the Arduino ide
            4.All hardware and software are open source

        c. Shell

            KC868-Server / KC868-H32BS / KC868-HxB series: industrial grade metal shell
            KC868-A series: plastic shell

        d. Match the available products of different models according to the load control mode

            ON/OFF Switch type: such as light, curtain, shutter, valve, garage door
            Products: KC868-Server / KC868-H32BS / KC868-HxB series / KC868-A series

            38kHz infrared signal, 433MHz RF signal type: curtain, shutter, air conditioner, TV, multimedia player
            Products: KC868-Server / KC868-AG / KC868-Uair / KC868-G
            KC868-Server / KC868-AG / KC868-Uair : need write arduino IDE code or config in ESPHome to use.
            KC868-G: only directly use by "KinCony Smart Home" app or integrate into third part software platform.

            Dimming type: dimming bulb, RGBW LED strip
            Products: KC868-Server / KC868-A series / KC868-D8

            KC868-D8: 12V LED Driver or AC110V-380 SSR load driver (For SSR, if want install on DIN RAIL, just add the heat sink)

        e. Automatic control solution

            KC868-Server
            Node-Red / home assistant installed on raspberry pi
            Make logical or write code for any functions by yourself
            Logical control by raspberry pi

            KC868-COLB
            Just use KC868-COLB’s software to config and set directly.
            It’s easy to use, not complex logical conditions. Logical control by local CPU inside.
            KC868-COLB can be integrate with KC868-Server

            KC868-COLB is a input module , connect with all sensors, it can do IFTTT automatic command to control KC868-H32BS or KC868-H32B controller. KC868-Server also can make logical , it have 16 channel DI and 4 channel AI and some GPIOs for DIY, if not enough input ports for use, then you can integrate KC868-COLB to KC868-Server by MQTT, so that will add 16 channel DI + 16 channel AI +5 channel temperature sensors.
