ESP32: ETH + RELAY

[zital]

this code of python in esp32 works:

Code:

import network
import socket
from machine import Pin
import time

# Wi-Fi credentials
WIFI_SSID = "WIFI_NAME"
WIFI_PASS = "WIFI_PASSWORD"

# GPIO pins for relays (active LOW)
RELAY1_GPIO = 15
RELAY2_GPIO = 2

# Setup GPIOs
relay1 = Pin(RELAY1_GPIO, Pin.OUT, value=1)
relay2 = Pin(RELAY2_GPIO, Pin.OUT, value=1)

def set_relay(relay_num, on):
    gpio = relay1 if relay_num == 1 else relay2
    gpio.value(0 if on else 1)

# Connect to Wi-Fi
def wifi_connect():
    wlan = network.WLAN(network.STA_IF)
    wlan.active(True)
    if not wlan.isconnected():
        print(f"Connecting to {WIFI_SSID} ...")
        wlan.connect(WIFI_SSID, WIFI_PASS)
        while not wlan.isconnected():
            time.sleep(0.5)
            print(".", end="")
    print("\nConnected, IP:", wlan.ifconfig()[0])

# HTTP response helpers
def http_response(conn, body):
    conn.send(b"HTTP/1.1 200 OK\r\n")
    conn.send(b"Content-Type: text/plain\r\n")
    conn.send(b"Content-Length: %d\r\n" % len(body))
    conn.send(b"\r\n")
    conn.send(body)

# HTTP server
def start_server():
    addr = socket.getaddrinfo('0.0.0.0', 80)[0][-1]
    s = socket.socket()
    s.bind(addr)
    s.listen(1)
    print("HTTP server listening on port 80")
    while True:
        try:
            conn, addr = s.accept()
            print("Client connected from", addr)
            request = conn.recv(1024).decode()
            print("Request:", request)
            path = ""
            try:
                path = request.split(" ")[1]
            except:
                pass

            if path == "/":
                body = (
                    "ESP32 Relay Control:\n"
                    "/relay1/on  or /relay1/off\n"
                    "/relay2/on  or /relay2/off\n"
                )
            elif path == "/relay1/on":
                set_relay(1, True)
                body = "Relay 1 ON"
            elif path == "/relay1/off":
                set_relay(1, False)
                body = "Relay 1 OFF"
            elif path == "/relay2/on":
                set_relay(2, True)
                body = "Relay 2 ON"
            elif path == "/relay2/off":
                set_relay(2, False)
                body = "Relay 2 OFF"
            else:
                body = "Invalid path"

            http_response(conn, body.encode())
            conn.close()
        except Exception as e:
            print("Error handling connection:", e)

# Main app
wifi_connect()
start_server()

Now, I'm going to try to do it with Ethernet
