Dear Sir

I have a problem on my Node-red with relay H32B Pro, when i connect to relay and debug it alway run message "RELAY-STATE-255,0, 1,0,0, OK" at every 2 second.
Can you tell me what wrong?

Any plans on making a KC868-H16BS or KC868H8BS?

In the case of using the home assistant

How can a custom dashboard be made for each user, separate from the other user?
So that no user can access the page of the other user

Hi,
I was able to connect my hb868 32 pro to my local mqtt.
I have few questions
1. the mqtt broker seems to work only on wifi - when I try to configure the local ip on the ethernet interface it does not change the default ip. is this the case?
2. is it possible to configure a feedback on mqtt of the pressed button? like, when I press my switch 3 to send an mqtt message that relay3 is on. 
3. how can I configure the behavior for multiple clicks?

Thank you!

Hi,

i use this simple code for read value from pins anolog input (0-5V) PIN A3 and A4. At pin A3 connect 0V at pin A4 connect stable 2.5 V and reading value.

#define ANALOG_PIN_A3  32
#define ANALOG_PIN_A4  33

void setup() {
  // put your setup code here, to run once:
Serial.begin(115200);
pinMode(ANALOG_PIN_A3,INPUT);
pinMode(ANALOG_PIN_A4,INPUT);
}
int analog_value_3 = 0;
int analog_value_4 = 0;
void loop() {
  // put your main code here, to run repeatedly:
analog_value_3 = analogRead(ANALOG_PIN_A3);
analog_value_4 = analogRead(ANALOG_PIN_A4);
Serial.printf("Current reading on Pin (%d)=%d\n",ANALOG_PIN_A3,analog_value_3);
Serial.printf("Current reading on Pin (%d)=%d\n",ANALOG_PIN_A4,analog_value_4);

delay(2000);
}


At serial monitor i see this result

Current reading on Pin (33)=1889
Current reading on Pin (32)=0
Current reading on Pin (33)=1872
Current reading on Pin (32)=0
Current reading on Pin (33)=1875
Current reading on Pin (32)=0
Current reading on Pin (33)=1875
Current reading on Pin (32)=0
Current reading on Pin (33)=1872
Current reading on Pin (32)=0
Current reading on Pin (33)=1920
Current reading on Pin (32)=0
Current reading on Pin (33)=1872
Current reading on Pin (32)=0
Current reading on Pin (33)=1873
Current reading on Pin (32)=0
Current reading on Pin (33)=1879
Current reading on Pin (32)=0
Current reading on Pin (33)=1872
Current reading on Pin (32)=0
Current reading on Pin (33)=1872
Current reading on Pin (32)=0
Current reading on Pin (33)=1873
Current reading on Pin (32)=0
Current reading on Pin (33)=1888
Current reading on Pin (32)=0
Current reading on Pin (33)=1871
Current reading on Pin (32)=0
Current reading on Pin (33)=1865



VALUE of PIN 4 (33)  is NOT STABLE the value varies, it pulsates +/-20 or more, max 1920 , minimum 1865. It is normaly ? Can i solve it ?

Hello,
I'm trying to use MCCI LoRaWAN LCCI library to connect to the Things Network, however the library requires IO1 pin of the SX1278 module to be connected to an GPIO of the ESP32.

I soldered a wire from SX1278 IO1 to ESP32 GPIO13 as that appears free and looks like a suitable pin.  However after doing that, the serial port would no longer appear on my PC, when i removed the jumper wire everything returned to normal.

Can you suggest any solutions?  Is GPIO13 ok for use?

Thanks in advance.

Hi all,

I want to measure Carbon dioxide PPM levels using the MH-Z19B sensor with my KC868-A4. The sensor uses UART and that means I need to use IO17 (#28 U2T) and IO16 (#27 U2R) but these are being used in the RS232 connector:

   

I see that I can easily use the IO16 (Number 9 from above picture) from the DB9 connector, but I don't know what is happening to IO17 (Number 10 from above picture).

To summarize my question, how can I utilize IO17 and IO16 from a KC868-A4 board? Is it even possible to use MH-Z19B sensor with it? I'm using Tasmota on it.

I'm apologize if this is a dumb question, I'm new to all this.


Thank you in advance

Hey!

Im new and just discovered the Kincony relays and its probably the best solution for my problem

My goal is basically: I want to be able to get an event in home assistant when I press the RF remote or a toggle switch to open the garage/gate door, so I can create an automation primarily to turn on the lights at night
I would only use the Kincony relay for the garage door and gate, my lights are already connected to home assistant

eg
toggle switch button was pressed, garage door opens -> turn on lights for 5min
or RF remote button was pressed, garage door opens -> turn on lights for 5min

Im a bit confused on 2 things
It says on the website the outputs are "277VAC 10A, 125VAC 12A", and I see nearly all other relay described as AC output aswell, the garage door and the gate is a 12v relay, can I still connect it?
When I connect a normal toggle light switch on the inputs to open the garage, can I set it up in "hold" and "toggle" mode or how is that managed? 

Thank you!

Here is KC868-A16 integrate with home assitstant by MQTT via "KCS" v1.0.15 firmware.
