I have a project involving three motors that I would like to connect to a wind sensor, a light sensor, and a light LED sounder sensor. For power, I will use a solar panel connected to a battery, which will provide power to a relay controller. Which relay controller should I use, and what steps should I follow?
Thank you!

Dear,

Why add external relays if the controller A32 pro has its own internal relays?

Hello
How to get ssd1306 oled display to work in a same solution with digital in and out.
Both works in its own solution, but not together each others.
Looked like they are both using same clk and dma?

Hello, is there a way in the KC868-A32 to activate the output relays via HTTP commands?

Thanks,
Alan

Hi,

Do you have a scheme to explain how to connect a NTC Thermistor sensor B3950 10K to a KC868 S series (the wire and if something else is necessary to add) ?

thanks.

Modbus protocol:

A. input register function:

temperature : 16bit unsigned integer register
humidity: 16bit unsigned integer register

address    function
0000H        temperature value
            unit: ℃
            fixed 1 decimal
            (1) >0℃: register data<10000
                          for example: register value=250, actual temperature: 250*0.1=25℃
            (2) <0℃: register data>=10000
                          for example: register value=10250, actual temperature: -1*(10250-10000)*0.1=25℃
------------------------------------
0001H        humidity value
            unit: %RH
            fixed 1 decimal
                          for example: register value=500, actual humidity: 500*0.1=50(%RH)
------------------------------------
0002H        temperature value
0003H        unit: ℃  decode: 32bit float data
------------------------------------
0004H        humidity value
0005H        unit: %RH  decode: 32bit float data


B. Hold register function:
The contents of the register are saved when power is turned off. The holding register is a readable and writable register. The value in each register is a 16-bit unsigned integer.

address    function
0000H        temperature value
            unit: ℃
            fixed 1 decimal
            (1) >0℃: register data<10000
                          for example: register value=250, actual temperature: 250*0.1=25℃
            (2) <0℃: register data>=10000
                          for example: register value=10250, actual temperature: -1*(10250-10000)*0.1=25℃
------------------------------------
0001H        humidity value
            unit: %RH
            fixed 1 decimal
                          for example: register value=500, actual humidity: 500*0.1=50(%RH)
------------------------------------
0002H        temperature value
0003H        unit: ℃  decode: 32bit float data
------------------------------------
0004H        humidity value
0005H        unit: %RH  decode: 32bit float data
------------------------------------
000AH        RS485 bus address(1-255), default:1 
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.
------------------------------------
000BH        Baud rate setting:
            0:4800  1:9600(default) 2:14400 3:19200 4:38400 5:56000 6:57600 7:115200
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.
------------------------------------
003DH        Parity settings
            0:None(default)  1:odd parity 2:even parity
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.

modify RS485 setting command:

register:
1001：SLAVE address 1-250
1002：Baud rate: baud_arr[8] = {4800,9600,14400,19200,38400,56000,57600,115200}
1003: Parity bit: parity_arr[3] = {UART_PARITY_NONE,UART_PARITY_EVEN,UART_PARITY_ODD}


how to remember RS485 address if you forget it.
1: every time power on will output board information by RS485 (9600,8,N,1) if you forget the board's address.
2: hold on button > 2 seconds, will reset to factory setting, default RS485 address=1

Hi,

I came across your Youtube channel and was wondering if you would help me design a solution for my Off Grid Expedition Camper Truck.

I would like to monitor and ultimately control all items via Alex Hub.

I am currently in the process of building the vehicle and all electrics are going to be supplied using Victron System (Inverter), via Batteries/Solar/240V hook up.

The system will have a 240V AC requirement with 17 Circuit Breakers and a 12V Circuit with 36 fused (Spade type or can be railed DC Breakers).

Is this something you can help with?

I wait your reply.

Many Thanks

Dion Mack

hi, i would be interested in using kc868 M16-V2 with home assistant. but i would need to know the power of each channel (and not the current) can the board calculate it for each channel?

Good afternoon, I have a Kincony F16 and I am interested in removing Tuya from the .yaml file and keeping only ESPHome. I do it another way to connect from outside the home and I don't need Tuya. Could you tell me exactly what I have to remove so that nothing remains of  en el archivo .yaml "F16-HA.txt". I'm afraid I won't be able to connect if I delete something by mistake. Thank you.
