Health/HealthDate

What are variables [tt]Health/HealthDate (ZWaveDevice)[/tt] supposed to contain?

Health is a value from 1 to 5 for a health score from the last heal, and HealthDate is when the health score was calculated.
health 5 = excellent
health 1 = can’t talk to node at all
In between means it’s not 100% reliable or it’s slow.
