MQTT sensors to MQTT broker, not one device

[marc115uk]

Each sensor that is published into my mqtt broker shows as an individual device, rather than one devices with multiple entities, as you can see from my mqtt explorer, believe this is why it is not auto discovering in my home assistant

Might be the reason why I see this error:

"This entity ('sensor.voltronic_ac_charge_on') does not have a unique ID, therefore its settings cannot be managed from the UI. See the documentation for more detail."
