Esp8266 lamp controlled also from HA

Configuration Frontend
1

I have a lamp that is controlled by a esp8266 using a webserver, I want to also control that lamp from HA.

The relevant code from the lamp is this

  server.on("/LED", HTTP_POST, handleLED);  // Call the 'handleLED' function when a POST request is made to URI "/LED"
  server.onNotFound(handleNotFound);        // When a client requests an unknown URI (i.e. something other than "/"), call function "handleNotFound"

  server.begin();                           // Actually start the server
  Serial.println("HTTP server started");
  
}

void loop() {
  // Check the state of the foot switch and toggle the relay accordingly
  if (digitalRead(pinIntrerupator) != pozVeche) 
  {
    pozVeche = digitalRead(pinIntrerupator);
    digitalWrite(releu, !digitalRead(releu));
  }
  
  // Handle HTTP requests from clients if WiFi is connected
  if (WiFi.status() == WL_CONNECTED) {
    server.handleClient();
  }
  
  delay(100);
}

void handleLED() {                          // If a POST request is made to URI /LED
  digitalWrite(releu,!digitalRead(releu));      // Change the state of the LED
  server.sendHeader("Location","/");        // Add a header to respond with a new location for the browser to go to the home page again
  server.send(303);                         // Send it back to the browser with an HTTP status 303 (See Other) to redirect
}

void handleRoot(){                          // When URI / is requested, send a web page with a button to toggle the LED
   // server.send(200, "text/html", "<form action=\"/LED\" method=\"POST\"><input type=\"submit\"value=\"Comuta\"></form>");
    server.send(200, "text/html", "<form action=\"/LED\" method=\"POST\"><input type=\"submit\" value=\"Comuta\" align=\"middle\" style=\"display:block; margin-left:auto; margin-right:auto; margin-top:150px; background-color:#f44336; font-weight:800; height:230px; color:white; font-size:110px; width:50%;\"></form>");
}
void handleNotFound(){
   server.send(404, "text/plain", "404: Not found"); // Send HTTP status 404 (Not Found) when there's no handler for the URI in the request
}

I tryed doing what this tutorial says but couldn’t get it to work.

Then I tried this:

switch:
  - platform: rest
    name: Lampa Birou
    icon: mdi:cat
    resource: http://192.168.100.6/LED
    method: POST
    headers:
      Content-Type: application/x-www-form-urlencoded
    body_on: ""
    body_off: ""

but it also doesn’t work, it doesen’t even show me the switch in developer-tools/state.

I’ve only installed HA today so I don’t know anything, any help wold be appreciated.

Thanks!

If the lamp is controlled by a esp why is it not ESP-Home on it?

3

Besides, as Hellis81 said, that using ESPHome would make your life easier, did you confirm the HTTP call is working outside of HA, e.g. via curl, and with what command?

4

I’m not using ESPHome because I made that lamp years ago before I knew about HA or ESPHome. It’ s been reliable and I don’t intend to change it.

5

You have one input pin and one output pin to drive a relay.
That’s about six lines in ESP-Home.
I bet it will be faster to make it ESP-Home than trying to get this working.
You could actually buy a new ESP and preprogram it, then just make a quick swap.

Yes it works with:

curl -X POST http://192.168.100.6/LED

The physical installation isn’t exactly easily accesibile and right now I’m just playing with HA, I don’t know if I’ll keep using it so I preffer to not change what I have and is working.
But I’m more than happy to learn so if you could tell me those 6 lines of code I’d appreciate it.
Also in the original post I said that the switch doesen’t appear anywhere and I don’t know what I’m doing wrong so that that would be useful to know.

Have a good day and thank You!
