Contact sensor on Arduino IDE - Trigger Alexa routine (MEGH-5311)

[lukeferrero]

Is your feature request related to a problem?

I need to trigger Alexa routines, to do this I need a contact sensors or motion sensor type device. In the examples there are only "standard device". Is it possible to obtain an example with this kind of device? I also tried to modify the switch example but those standard types seems not available. Thank you.

Please check out the custom air cooler example for reference. There you will see that custom device type my.device.air-cooler has been used while defining a device . Similarly, some parameters are defined like here, with the types (Eg. ESP_RMAKER_PARAM_MODE) passed explicitly. Just use standard sensor device types and the corresponding param types from this page, and that should be sufficient.

Thank you. I try the example.

When i try to compile with a standard sensor type like "doorbell" i've a compilation errror, "not recognized type":

my_switch = new Doorbell("Doorbell", &gpio_switch);

It seems very simple but it doesn't work for me... Thanks

[lukeferrero]

Another question, If I have to create a new device, how should I declare a parameter so that Alexa interprets it as a contact or a motion sensor so that I can trigger a routine? Thanks

[lukeferrero]

This is code, I just need to create a device recognized by Alexa as a button to trigger a routine

//This example demonstrates the ESP RainMaker with a custom Air Cooler device

include "RMaker.h"

include "WiFi.h"

include "WiFiProv.h"

define DEFAULT_doorbell false

const char service_name = "PROV_123"; const char pop = "abcd123";

static int gpio_doorbell = 17; static int gpio_reset = 0;

// The framework provides some standard device types like switch, lightbulb, fan, temperature sensor. // But, you can also define custom devices using the 'Device' base class object, as shown here static Device *my_device = NULL;

// WARNING: sysProvEvent is called from a separate FreeRTOS task (thread)! void sysProvEvent(arduino_event_t *sys_event) { switch (sys_event->event_id) { case ARDUINO_EVENT_PROV_START:

if CONFIG_IDF_TARGET_ESP32S2

    Serial.printf("\nProvisioning Started with name \"%s\" and PoP \"%s\" on SoftAP\n", service_name, pop);
    printQR(service_name, pop, "softap");

else

    Serial.printf("\nProvisioning Started with name \"%s\" and PoP \"%s\" on BLE\n", service_name, pop);
    printQR(service_name, pop, "ble");

endif

    break;
case ARDUINO_EVENT_PROV_INIT:
    wifi_prov_mgr_disable_auto_stop(10000);
    break;
case ARDUINO_EVENT_PROV_CRED_SUCCESS:
    wifi_prov_mgr_stop_provisioning();
    break;
default:;
}

}

void write_callback(Device device, Param param, const param_val_t val, void priv_data, write_ctx_t ctx) { const char device_name = device->getDeviceName(); const char param_name = param->getParamName();

if (strcmp(param_name, "doorbell") == 0) { Serial.printf("\nReceived value = %s for %s - %s\n", val.val.b ? "true" : "false", device_name, param_name); bool doorbell = val.val.b; (doorbell == false) ? digitalWrite(gpio_doorbell, LOW) : digitalWrite(gpio_doorbell, HIGH); param->updateAndReport(val); } }

void setup() { Serial.begin(115200); pinMode(gpio_reset, INPUT_PULLUP); pinMode(gpio_doorbell, OUTPUT); digitalWrite(gpio_doorbell, DEFAULT_doorbell);

Node my_node;
my_node = RMaker.initNode("ESP RainMaker Node");
//my_device = new Device("Doorbell", "my.device.doorbell", NULL); 
my_device = new Device("Doorbell", NULL, NULL); 
if (!my_device) {
    return;
}

Param sensor("doorbell", ESP_RMAKER_PARAM_TOGGLE, value(DEFAULT_doorbell), PROP_FLAG_READ);
sensor.addUIType(ESP_RMAKER_UI_TOGGLE);
my_device->addParam(sensor);

my_device->addCb(write_callback);

//Add custom Air Cooler device to the node
my_node.addDevice(*my_device);

//This is optional
// RMaker.enableOTA(OTA_USING_TOPICS);
//If you want to enable scheduling, set time zone for your region using setTimeZone().
//The list of available values are provided here https://rainmaker.espressif.com/docs/time-service.html
// RMaker.setTimeZone("Asia/Shanghai");
//Alternatively, enable the Timezone service and let the phone apps set the appropriate timezone
// RMaker.enableTZService();

//RMaker.enableSchedule();

//RMaker.enableScenes();

RMaker.start();

WiFi.onEvent(sysProvEvent);  // Will call sysProvEvent() from another thread.

if CONFIG_IDF_TARGET_ESP32S2

WiFiProv.beginProvision(WIFI_PROV_SCHEME_SOFTAP, WIFI_PROV_SCHEME_HANDLER_NONE, WIFI_PROV_SECURITY_1, pop, service_name);

else

WiFiProv.beginProvision(WIFI_PROV_SCHEME_BLE, WIFI_PROV_SCHEME_HANDLER_FREE_BTDM, WIFI_PROV_SECURITY_1, pop, service_name);

endif

}

void loop() { if (digitalRead(gpio_reset) == LOW) { //Push button pressed

    // Key debounce handling
    delay(100);
    int startTime = millis();
    while (digitalRead(gpio_reset) == LOW) {
        delay(50);
    }
    int press_duration = millis() - startTime;

    if (press_duration > 10000) {
        // If key pressed for more than 10secs, reset all
        Serial.printf("Reset to factory.\n");
        RMakerFactoryReset(2);
    } else if (press_duration > 3000) {
        Serial.printf("Reset Wi-Fi.\n");
        // If key pressed for more than 3secs, but less than 10, reset Wi-Fi
        RMakerWiFiReset(2);
    } 

}
delay(100);

Hello, I'd like to develop a project with Espressif but I've to solve the problem described, can you help me? Thanks in advance, Luca

@lukeferrero Please check the pointers in my comment above once again for better understanding.

Your code has the device defined as my_device = new Device("Doorbell", NULL, NULL);. Instead it should be my_device = new Device("Doorbell", "esp.device.doorbell", NULL);

Please refer the standard types document once again to understand valid device types and the parameters required under them.

[lukeferrero]

Thank you very much Piyush Shah.

I modified the code but Alexa still to recognize the device not as a valid trigger for routine... I also tried to modify parameter, etc. but nothing. I just need a working example...

I read in details this post https://github.com/espressif/esp-rainmaker/issues/174 I tried to create a Lock (in Arduino) but the parameter ESP_RMAKER_PARAM_LOCKSTATE is not recognized. Any suggestion? Thanks

[shahpiyushv]

Did you also you try creating the parameter using Param sensor("lockstate", "esp.param.lockstate", value(0), PROP_FLAG_READ);

[lukeferrero]

It works! Thank you
