Add NodeAlive event to the ZWaveNode class, and add lastSeen property to the NodeStatistics class.

No idea why I didn't include Alive (the most basic of events 😮 ) - Thanks!
Will get it merged tonight!

@spudwebb

Can you do me favour?

set lastSeen, in the statistics, and ZWaveNode class (its there also) as DateTime

The original output should hopefully be ISO 8601 and Im thinking it should parse to DateTime?

I have no way to test on my system currently

[spudwebb]

yes it parses to DateTime. 2 questions:

1. lastSeen reported by ZWave JS seems to be an UTC time, do we want to convert it to a local time or do we want to keep it as UTC?
2. when it is null, it is parsed as 0001-01-01T00:00:00 because DateTime is a struct and it is its default value. Do we want to use a nullable property instead DateTime?, so that we can have a null value for this property?

[marcus-j-davies]

1. My Vote is UTC - allow the front end to massage as seems fit?
2. I think a nullable object (I think we have a few in place already)

[spudwebb]

Done and tested.

Merged!
