fauxmo.onMessage

So i was working on a project with alexa and I got this error message

Arduino: 1.8.6 (Mac OS X), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, 4M (1M SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

   fauxmo.onmessage(callback);
          ^
exit status 1

This report would have more information with

and I dont know how to fix it. Here is the code:

ANY HELP IS APPRECIATED!!!

Where did you get the idea that the library has a method called onmessage ?

Look in the fauxmoESP.h file to see which methods are available

Hello!

Have the same issue and I have no clue how to solve the issue:

#include <Arduino.h>
#include <fauxmoESP.h>
#include <ESP8266WiFi.h>

#define WIFI_SSID "******"
#define WIFI_PASS "******"
#define SERIAL_BAUDRATE 115200

fauxmoESP fauxmo;

// -----------------------------------------------------------------------------
// Wifi
// -----------------------------------------------------------------------------

void wifiSetup() {

// Set WIFI module to STA mode
WiFi.mode(WIFI_STA);

// Connect
Serial.printf("[WIFI] Connecting to %s ", WIFI_SSID);
WiFi.begin(WIFI_SSID, WIFI_PASS);

// Wait
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
delay(100);
}
Serial.println();

// Connected!
Serial.printf("[WIFI] STATION Mode, SSID: %s, IP address: %s\n", WiFi.SSID().c_str(), WiFi.localIP().toString().c_str());
}

void callback(uint8_t device_id, const char * device_name, bool state) {
Serial.print("Device "); Serial.print(device_name); 
Serial.print(" state: ");
if (state) {
Serial.println("ON");
digitalWrite(D2,HIGH);
} else {
Serial.println("OFF");
digitalWrite(D2,LOW);
}
}

void setup() {
// Init serial port and clean garbage
Serial.begin(SERIAL_BAUDRATE);
Serial.println("FauxMo demo sketch");
Serial.println("After connection, ask Alexa/Echo to 'turn <devicename> on' or 'off'");

pinMode(D2,OUTPUT);

// Wifi
wifiSetup();

// Fauxmo
fauxmo.addDevice("Fish Tank");
fauxmo.onMessage(callback);
}

void loop() {
fauxmo.handle();
}

Do you really have the same error?
The other guy seems to have had a problem with camelCase.

Please post your error message(s)

As per reply #1 there is no onMessage method in the faxuMoESP library.

It looks like you and the original poster are both borrowing code from this guide at the Adafruit website.

I don't know what happened for sure, but it looks like the library has changed and the Adafruit website is out of date.

Maybe you can get hold of an old version of the library that still has the onMessage method.

Hello!

Fish_TANK:62:16: error: 'class fauxmoESP' has no member named 'onMessage'

As previously noted the fauxmoESP library has no function named onMessage, hence the error message.

Please post the fauxmoESP.h file here

Here's an extract from the changelog in that library.

## [2.3.0] 2017-11-08
...
### Deprecated
- Use onSetState callback instead of onMessage callback
- Use onGetState callback instead of setState method

I can't tell if it's a straight name change, but it looks like the onMessage has been replaced by onSetState.

{edit - date of changelog entry added}

As suspect the library has no function named onMessage() so it looks like it has either been changed or there is more than one version of it
