Trying to modify Garage Door Monitor to work with an ecolink tilt sensor

However, I keep getting events like:
Notify got evt physicalgraph.app.EventWrapper@299d74b4
When I’m looking for the last “contact” event and want to know if it was “open” or “closed”.

In the ide for the device I see what I expect - a contact event and a value of open or closed.

I must be missing something really basic.

Thanks!
