Feature Request: Say when last report was received

[hairyfred]

Not sure if this is possible because you put how far back in reports you want, but it would be useful for the output to say "last report received at X" or under missing keys say when it was last seen.

Either way keep up the good work, glad to finally have a way of easily integrating into home assistant :)

I see how that would be useful. It would make more sense for the Home Assistant integration to track it, if that is where you'd like to use the information.

Still, the output could be saved to a text file and updated when an item is reported. I'll play with that idea, it's an interesting challenge. :)
