Hi Tony, Would it make sense to create a couple of Jiras for improving the virtual sensor performer so that we can discuss the improvement in the jira?
I'm thinking one Jira for the REST interface. Then, it might make sense to add a Jira covering features for; for examples, sensors you'd see in a weather station: air speed and direction, precipitation type and depth, and so on.
