Hello everyone!
I need your help for my project which consists of automating the heating of my spa thanks to my solar thermal panel.
I made the code in Arduino IDE for my tests which works well.
The principle of the installation is a spa, a solar thermal panel. Each has a temperature probe, and depending on the temperatures collected, turn on or off the pump which circulates the water and therefore heats it or not.
This system is good, but I have no visual feedback of the data. So I would like to transform this .ino code into yaml to integrate it into EspHome of Home Assistant, first to see the temperatures and if the pump is running or not. Maybe after add a button to turn the pump on or off manually (2nd step that).
Here is my .ino code that works well:
#include <OneWire.h>
#include <DallasTemperature.h>
// Pin où les sondes DS18B20 sont connectées
const int ONE_WIRE_BUS = 4;
// Configuration du bus OneWire
OneWire oneWire(ONE_WIRE_BUS);
// Configuration du capteur Dallas Temperature
DallasTemperature sensors(&oneWire);
// Adresses des sondes détectées
DeviceAddress spaProbe = {0x28, 0x30, 0xA2, 0x6A, 0x00, 0x00, 0x00, 0xC8};
DeviceAddress panelProbe = {0x28, 0xDA, 0x86, 0x6C, 0x00, 0x00, 0x00, 0xC0};
// Pin de contrôle pour la pompe
const int POMPE_PIN = 2;
void setup() {
// Initialisation de la communication série
Serial.begin(115200);
Serial.println("Initialisation des sondes DS18B20...");
// Initialisation des capteurs
sensors.begin();
// Configuration de la pin de la pompe en sortie
pinMode(POMPE_PIN, OUTPUT);
digitalWrite(POMPE_PIN, LOW); // Assure que la pompe est éteinte au démarrage
}
void loop(void) {
// Demande de mise à jour des températures
sensors.requestTemperatures();
// Lecture des températures
float tempSpa = sensors.getTempC(spaProbe);
float tempPanel = sensors.getTempC(panelProbe);
// Affichage des températures
Serial.print("Température du spa : ");
Serial.print(tempSpa);
Serial.println(" °C");
Serial.print("Température du panneau solaire : ");
Serial.print(tempPanel);
Serial.println(" °C");
// Régulation de la pompe
if (tempPanel > tempSpa + 5 && tempSpa < 37) {
// Température du panneau solaire est suffisamment élevée et la température du spa est inférieure à 37°C
digitalWrite(POMPE_PIN, HIGH); // Activer la pompe
Serial.println("Pompe activée");
} else {
// Conditions non remplies
digitalWrite(POMPE_PIN, LOW); // Désactiver la pompe
Serial.println("Pompe désactivée");
}
// Attendre 5 secondes avant la prochaine lecture
delay(5000);
}
Here is my yaml code that does not work at all:

Thanks for your help, but maybe there is another way to do it than coding the yaml file.
