ESP8266 (nodemcu) send updates just once after startup

[andrewhack]

I noticed an issue (not sure if is my mistake) when using the library with nodemcu, no updates are send after the first one at the initial startup. For example, similar code with Arduino works fine.
Any suggestions?

The code:

WiFiClient client;
HADevice device;
HAMqtt mqtt(client, device);
HASensorNumber Sensor("Sensor");

void setup() {
..................................................
  device.setUniqueId(mac, sizeof(mac));
  device.setName("controller");
  device.setSoftwareVersion("1.0.dummy");
  Sensor.setIcon("mdi:flash-triangle");
  Sensor.setName("Sensor");
..................................................
  mqtt.onConnected(onConnected);
  mqtt.onMessage(onMessage);
  mqtt.begin(BROKER_ADDR, BROKER_USERNAME, BROKER_PASSWORD);
...................................................

void loop() {
........................................................
  mqtt.loop();
........................................................
}
void onConnected() {
    Sensor.setValue(float(sensor));
}

void onMessage(const char* topic, const uint8_t* payload, uint16_t length) {
 .......................................................
}

I encountered the same with my BinarySensor on ESP-32.

MQTT Explorer sees all the messages but Home Assistant does not recognize them as state changes for some reason.

Update: I have no idea why but changing MQTT broker from nanomq to mosquito helped and now everything works.

I am using mosquito and have the issue. Actually I don't see any updates to the broker.
The strange thing is when the controller performs another TCP operation, the update is sent.
The difference in the arduino code comparing with nodemcu code is this line (as per the example):

Ethernet.maintain();

Actually I am not sure what this do.
