I'm not able to see my 'device/entitiy' in Home Assistant. about hamqttdevice

Additional info.
I have changed again the discovery_prefix in this way:
HAMqttDevice light("My Nice Lamp", HAMqttDevice::LIGHT, "homeassistant");
And in the code:
client.subscribe("/homeassistant/status", [] (const String &payload)
In this way now I'm able to see the entity inside the list of entities (not visible in the MQTT integration, but I'm not sure if this is an error).

Did you ever get this working @gigios? I'm having the same issue. I connect to the MQTT broker, everything gets sent out for the config, but it never shows up in HA.

No, I'm currently testing ESPHome. Easier to configure but more 'rigid' in some settings.
The ideal would be to be able to make the library work but at the moment I don't have much time to understand where I'm wrong.

Hello,

Never put a "/" before the prefix.

Doing this will not work:

HAMqttDevice light("My Nice Lamp", HAMqttDevice::LIGHT, "/homeassistant");
...
client.subscribe("/homeassistant/status", [] (const String &payload)

Doing this is ok :

HAMqttDevice light("My Nice Lamp", HAMqttDevice::LIGHT, "homeassistant");
...
client.subscribe("homeassistant/status", [] (const String &payload)

Also, the MQTT library used by this lib have a maximum payload size that is not really big. If you exceed the payload size, the config payload will not be sent and Home Assistant will not see your device.

Try to add this line in setup() to increase the maximum MQTT payload size to 512 bytes :

client.setMaxPacketSize(512);

See this line from the RGBW exemple.

I ended up creating a HA script that sets up all my new MQTT entities under a single HA device. Then I just skipped this whole library and manually publish updates using his other library EspMQTTClient. I wanted more customizable topics anyway.
