Brewpiless runs better on esp32 or esp8266?

Hi, my first temperature controller was installed on an ESP8266, it runs great and sends me data to thingspeak every 30 seconds.

As I liked the operation so much, I decided to buy a pair of ESP32, thinking that everything would be much better, however I see that the ESP8266 is stable and the ESP32 suddenly stops transmitting data and stays in an idle state for a long time, so much so that I have to turn it off and on again for it to work again.

Maybe it could be some bad electronic connection that I cannot identify, but my esp8266 works very well and my 2 esp32s do not work as well as the esp8266.

Thank you

The answer is ESP32, it had electronic noise problems

• I have put a 4.7 pull up resistor in the middle of the SDA and 5V pin of the LCD display.

• I have put a 4.7 pull up resistor, in the middle of the SCL pin and 5V of the LCD display.

• I have put a ceramic capacitor in the middle of the 5V and GND pins that connect to the LCD display.

I think everything works correctly today

Apparently the problem was caused by electrical noise.
