The pi doesn't send the information to mqtt

[Idaho947]

Hello,

I have installed the program and I can read the value of the consumption index. However, I can't see anything in my MQTT broker (installed via mosquito). I don't see any error lines or problems in my configuration. Where can I look for more information (logs..)?

Hello,
I had the same problem as your description.
I found it was due to missing "client_id" when creating mosquitto client instance (https://mosquitto.org/api/files/mosquitto-h.html#mosquitto_new)

int main(int argc, char *argv[])
{
        struct tmeter_data meter_data;
        struct mosquitto *mosq = NULL;
        char buff[MQTT_MSG_MAX_SIZE];
        char meter_id[12];
        char mqtt_topic[64];

        sprintf(meter_id, "%i_%i", METER_YEAR, METER_SERIAL);


        mosquitto_lib_init();
-        mosq = mosquitto_new(NULL, true, NULL);
+        mosq = mosquitto_new("cc1101", true, NULL);
        if(!mosq){
                fprintf(stderr, "ERROR: Create MQTT client failed..\n");
                mosquitto_lib_cleanup();
                return 1;
        }

After having recompiled, I could get this result :

$ ./everblu_meters 
Client cc1101 sending CONNECT
Client cc1101 received CONNACK (0)
Client cc1101 sending SUBSCRIBE (Mid: 1, Topic: WaterUsage , QoS: 2, Options: 0x00)
Client cc1101 received SUBACK
Subscribed (mid: 1): 2

I hope it will help.
