Hello, I would like to use my controller for homekit control. I found out from the instructional videos that Relay 3 and 4 are on pins 2 and 15.
I would like to use more relays, and configure digital inputs as switches.
In further configuration I would like to use analog inputs and a temperature sensor.

#include <DS18B20.h>

DS18B20 ds(27);

void setup() {
    Serial.begin(9600);
}

void loop() {
 
    Serial.print(ds.getTempC());
    Serial.print("℃");
    Serial.println();
}

Can you please confirm the following wiring of the RC snubber with a KC868-H32B for a furnace valve is OK ?

Hi, I have a problem with one of my setups. H32B and input panel stops communicating after 6-10 tries.
After deset it is ok gor 6-10 tries and then stops.

We changed the input panel and it is the same problem. Communicating with Home assistant and mode red is working, Just the connection with panel and contoller.
H32B was not replaced.

Any suggestions?

Hi
I am designing a pressure controlled vacuum tank.
Software of ESP32 and
Nextion screen is OK

But I have problem when
I get digital input from (TMCB)
thermal magnetic circuit protector( schneider gv2me14)
When red fault contacts close I want to get information of fault of motor.  But esp32 reset itself .
