ESP32 and relay abnormal behavior

ESPHome
1

Yesterday, wanting to optimize the management of my aquarium, I programmed an ESP32 with esphome to use together with a display (model ST7735S), two temperature probes (models DS18B20) and a board with four relays (model Relay Module HL-545). Everything works fine except the relays that turn on and off continuously and very quickly (they seem to have gone crazy - HERE A VIDEO). What could it depend on? Is there a remedy? I also attach the script I created:

I hope you can help me.
Bye and thanks

What are these?
You need pullups/downs and some filtering there.

3

I wanted to read the status of the relays on the display (if you see the video you will understand better what I mean).
My intention is to read the status of each relay, the water temperature and the ambient temperature on the display.

Doesn’t make any sense to me.
If your relays are controlled by Esphome you already have the state.
But now you have gpios configured to change relay state every time they go high, either intentionally or just randomly as they are floating pins.

Edit:
You actually even correctly read the relay state:

Your binary sensors do nothing else than spam the relays.

Thank you very much to everyone who helped me, now thanks to your advice, everything works fine and I have even programmed four PINS to put 4 physical touch buttons and control the aquarium not necessarily from Home Assistant.
I write the code below:
