Hello,

I have a Kincony A16v3. I use the native mqtt integration for home assistant. ( MQTT(HA): ) and can see that the device is continuously updating the binary_sensors. I was wondering why you do this....

I would expect only mqtt messages are send when changes occur... not all the time. So if the input changes, then only at that time a mqtt message is send.

Can this be altered please? I'm considering buying the KC868 but then the mqtt broker will be flooded with messages.

Thanks in advance

Hi, I am Sim7600E kc868_A4S Model to call website URL after Internet activation. 

SIM Yellow Light is blinking. 

SIM call and SMS are working. But, Internet is not working. I have changed SIM Provider APN details


#include <HardwareSerial.h>

    Serial.println("No IP Address Assigned");
  }
}

OutPut  
13:57:40.249 -> >> AT
13:57:42.215 -> !! Timeout or Unexpected response:
13:57:49.212 -> SIM7600 not responding!


Note : SIM calling is working 
Note 2: SIM SMS are working.
Only Internet is not activated. I have to call website URL after Internet connected. 


   

Hello,

Who can help me, I have a KS868-A16 I would like 
to connect an I2s display 20x4) and show DS16B20 sensors on the 
display but I can't do it.

i use esphome, I have some DS16B20 sensors and they already work well with KS868-A16.

Greetings Mark

Hi,

I am using Serial.begin() and Serial.println() but I see nothing in my Serial Monitor (Platformio). What could the problem be?

I am using 115200 as monitoring speed (configured in platformio.ini) and my Serial monitor is configured with the same rate.

I am using the demo code below:

Tried to copy some RF-remotes i had laying around.
I go the RF-page and hit the "learn" button. all i got is a timeout.

Is there anything that needs to be done first to receive the RF-signals?
I tried this running v3.9.1.

Hi everyone,
I'm using the Kincony KC868-A6 V1.4 board and planning to connect several DS18B20 temperature sensors. I know these sensors can work with 3.3V, but they tend to be more stable with a 5V power supply—especially when using longer cables.
Does this board provide a dedicated 5V output pin that I can use to power the DS18B20 sensors? If so, where exactly can I find it on the board?
Any help or insights would be greatly appreciated!
Thanks in advance!

Can somebody test my code my wifi is dropping and cant connect to it after the update esphome

Hi, NooB Here.

Trying to program the ESP32 in PlatformIO:

1. Which ESP32 S3 chip should I configure when creating the project in PlatformIO?

2. How do I make it connect to upload? Do I need to hold a button before uploading? I tried holding the DL button but it didn't connect. Same for the RST button.

Thanks

Can I use 24V DC instead of 230V AC on relays?

I would like to use them to activate my 24VDC activated contactor (and then contactor would let 230V AC to pass through).
