Dear community,
I have successfully build a 4 temperature sensor using an ESP8266 including an OLED and upload of the measurements to thingspeak.
Now I would like to include Alexa controls. Do I have included the following libraries as described in many tutorials:
#include <AsyncPrinter.h>
#include <async_config.h>
#include <ESPAsyncTCP.h>
#include <ESPAsyncTCPbuffer.h>
#include <SyncClient.h>
#include <tcp_axtls.h>
#include <fauxmoESP.h>
Defined the following:
#define ID_OLED "OLED Display"
fauxmoESP fauxmo;
and then the following setup for the Alexa control:
//Setup Alexa control
//------------------------------------------
void FauxMoSetup(){
// By default, fauxmoESP creates it's own webserver on the defined port
// The TCP port must be 80 for gen3 devices (default is 1901)
// This has to be done before the call to enable()
fauxmo.createServer(true); // not needed, this is the default value
fauxmo.setPort(80); // This is required for gen3 devices
// You have to call enable(true) once you have a WiFi connection
// You can enable or disable the library at any moment
// Disabling it will prevent the devices from being discovered and switched
fauxmo.enable(true);
// Add virtual devices
fauxmo.addDevice(ID_OLED);
}
fauxmo.onSetState([](unsigned char device_id, const char * device_name, bool state, unsigned char value) {
// Callback when a command from Alexa is received.
// You can use device_id or device_name to choose the element to perform an action onto (relay, LED,...)
// State is a boolean (ON/OFF) and value a number from 0 to 255 (if you say "set kitchen light to 50%" you will receive a 128 here).
// Just remember not to delay too much here, this is a callback, exit as soon as possible.
// If you have to do something more involved here set a flag and process it in your main loop.
Serial.printf("[MAIN] Device #%d (%s) state: %s value: %d\n", device_id, device_name, state ? "ON" : "OFF", value);
if ( (strcmp(device_name, ID_OLED) == 0) ) {
// this just sets a variable that the main loop() does something about
Serial.println("OLED display switched by Alexa");
if (state) {
displayState = true; //Flag to switch on the display in the Mainloop
} else {
displayState = false; //Flag to switch off the display in the Mainloop
}
}
});
I get the following error message when compiling:
HTTP_DS18B20:279:2: error: 'fauxmo' does not name a type
fauxmo.onSetState([](unsigned char device_id, const char * device_name, bool state, unsigned char value) {
^
HTTP_DS18B20:298:4: error: expected unqualified-id before ')' token
});
^
exit status 1
'fauxmo' does not name a type
Can anyone point me in the right direction on how to resolve this issue?
Thanks a lot in advance!
