[BUG] No call-back when using Number component in HA

[leogaggl]

Describe the bug
Preface: not 100% this is a bug. Could potentially involve some PEBKAC :-). I have been using Switch and Sensor components quite nicely with ha-mqtt-discoverable (thanks for the excellent work BTW!). But I have been unable to get any callbacks on Number components.

I am not sure if the Number component https://www.home-assistant.io/integrations/number.mqtt/ behaves the same as the Switch in regards to callback.

Has anyone had experience with callbacks on NUMBER? Reading the value from Number object is also quite different.

To Reproduce
The Number components show up in HA (currently as sliders) and work fine. However, there has been no feedback from the Python daemon via MQTT. So any changes in HA are not reflected back to the device.

Expected behavior
The changes on the Number object in HA should be reflected back to the device via the MQTT state?

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Various Ubuntu, RaspiOS (shouldn't matter really
• Mosquitto:latest (Docker container)
• Python 3.12

I just realised that this seems to be related to: #194

I might close this one as it appears to be due to multiple components rather than the number entity.
