What am I missing? Why is it not working?
I can’t find anything usefull about “RefreshType”. Shouldn’t it be OpenClosedType, etc.?

When I’m not using toString inside sendCommand(…), there’s a lot of exception:

REFRESH is the only type of command that a Contact type Item accepts. You can’t command Contacts, really.

i had the same problem.
The documentation says: Contacts does not accept commands, only status updates.
So in my case i had to use postUpdate instead of sendCommand.
