Notifiche audio

Hello state that I am not a programmer, but I’m passionate about home automation, are the first weapons with OpenHab programming 1.8.3 and with a great deal of effort I managed to make something work.
With your help I installed Openhab of Bananapi and is functioning for a long time without problems.
Since the appetite comes with eating, I wish with a command I announced vocally by a Bluetouth speaker, the temperature of a room, or the state of an input and finally the weather forecast.
If possible I would need examples and step by step procedure …
I thank you in advance…
