LDR Light Sensor

[N5NMR]

Following the Example Code for Light Sensor with an LDR. Sensor shows value in Serial Monitor and is accepted by Apple Home as a new sensor BUT HomeKit says that this Sensor is not supported.

Any ideas?

@N5NMR Can you post the code for reference?

[N5NMR]

Sure, Here it is:

include

include

include "wifi_info.h"

const int ldrPin = A0;

define LOG_D(fmt, ...) printf_P(PSTR(fmt "\n") , ##__VA_ARGS__);

void setup() { Serial.begin(9600); wifi_connect(); // in wifi_info.h //homekit_storage_reset(); // to remove the previous HomeKit pairing storage when you first run this new HomeKit example my_homekit_setup(); }

void loop() { my_homekit_loop(); delay(10); }

//============================== // HomeKit setup and loop //============================== extern "C" homekit_server_config_t config; extern "C" homekit_characteristic_t cha_light;

void my_homekit_setup() { arduino_homekit_setup(&config); }

static uint32_t next_heap_millis = 0; static uint32_t next_report_millis = 0;

void my_homekit_loop() { arduino_homekit_loop(); const uint32_t t = millis(); if (t > next_report_millis) { // report sensor values every 10 seconds next_report_millis = t + 10 1000; my_homekit_report(); } if (t > next_heap_millis) { // Show heap info every 5 seconds next_heap_millis = t + 5 1000; LOG_D("Free heap: %d, HomeKit clients: %d", ESP.getFreeHeap(), arduino_homekit_connected_clients_count());

}

}

void my_homekit_report() { float ldrValue = analogRead(ldrPin); //int float licht = map(ldrValue, 0,1024,0,100); cha_light.value.float_value = licht; homekit_characteristic_notify(&cha_light, cha_light.value); LOG_D("Lichtlevel: %.1f", licht); }

This part of the code looks good, could you post the accessory (services, characteristic) setup too?

[N5NMR]

Sure, Thanks

include <homekit/homekit.h>

include <homekit/characteristics.h>

void my_accessory_identify(homekit_value_t _value) { printf("accessory identify\n"); }

// format: float; min 0.0001, max 100000 homekit_characteristic_t cha_light = HOMEKITCHARACTERISTIC(CURRENT_AMBIENT_LIGHT_LEVEL, 1);

homekit_accessory_t accessories[] = { HOMEKIT_ACCESSORY(.id=1, .category=homekit_accessory_category_sensor, .services=(homekit_service_t[]) {

    HOMEKIT_SERVICE(ACCESSORY_INFORMATION, .characteristics=(homekit_characteristic_t*[]) {
        HOMEKIT_CHARACTERISTIC(NAME, "Light Sensor"),
        HOMEKIT_CHARACTERISTIC(MANUFACTURER, "Jann´s Bastelbude"),
        HOMEKIT_CHARACTERISTIC(SERIAL_NUMBER, "23001"),
        HOMEKIT_CHARACTERISTIC(MODEL, "ESP8266 LDR"),
        HOMEKIT_CHARACTERISTIC(FIRMWARE_REVISION, "1.0"),
        HOMEKIT_CHARACTERISTIC(IDENTIFY, my_accessory_identify),
        NULL
    }),
    NULL
}),
NULL

};

homekit_server_config_t config = { .accessories = accessories, .password = "111-11-111" };
