Hallo Community,
ich baue grade einen "Finger" also Servo, welcher per Alexa auf einen Knopf drücken soll (SwitchBot).
Zum Start habe ich das FauxMo Beispiel-Skript versucht zu erweitern.
Dazu habe ich FauxMo auf meinem 8266 ESP WeMos Mini laufen. Alexa erkennt das Gerät auch prima.
Bei "Alexa schalte Finger ein" dreht er ein Stück, aber nicht mehr zurück. Er dreht auf die erste Postition, aber nicht mehr auf die zweite Position. Warum nur?
Im Skript seht ihr wie der Servo laufen muss. Er muss also um einen Knopf zu drücken einmal auf 10 Grad und dann 170 und dann wieder 10. Aktuell geht er nur auf die erste Position...
Was übersehe ich? (ganz unten im Skript - "myservo.write ...") - Delays habe ich mehrere probiert..
DANKE FÜR JEDEN TIPP! Bin noch recht neu im Thema...

// 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()

// You can enable or disable the library at any moment
// Disabling it will prevent the devices from being discovered and switched
fauxmo.enable(true);
// You can use different ways to invoke alexa to modify the devices state:
// "Alexa, turn yellow lamp on"
// "Alexa, turn on yellow lamp
// "Alexa, set yellow lamp to fifty" (50 means 50% of brightness, note, this example does not use this functionality)
// Add virtual devices
fauxmo.addDevice(ID_SERVO);
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);
// Checking for device_id is simpler if you are certain about the order they are loaded and it does not change.
// Otherwise comparing the device_name is safer.
if (strcmp(device_name, ID_SERVO)==0) {
digitalWrite(PIN_SERVO, state ? HIGH : LOW);
myservo.write(180); // tell servo to go to position in variable 'pos'
delay(50);
myservo.write(10);
delay(50);
myservo.write(180);
}
});
}
void loop() {
// fauxmoESP uses an async TCP server but a sync UDP server
// Therefore, we have to manually poll for UDP packets
fauxmo.handle();
// This is a sample code to output free heap every 5 seconds
// This is a cheap way to detect memory leaks
static unsigned long last = millis();
if (millis() - last > 5000) {
last = millis();
Serial.printf("[MAIN] Free heap: %d bytes\n", ESP.getFreeHeap());
}
// If your device state is changed by any other means (MQTT, physical button,...)
// you can instruct the library to report the new state to Alexa on next request:
// fauxmo.setState(ID_SERVO, true, 255);
}
Danke und LG

Parallel zeichne ich eben ein Gehäuse dafür, so dass man es mit PLA 3D ausdrucken kann... Wie soll sonst meine Senso angehen
