Rob,
I have a customer, Premium Power Systems, Kevin Johnson, 704-706-4327, that is having some trouble getting this set up.
This is a generator application and we think this is a good option for view and control.
Kevin, you should have all the functionality (one user) without a subscription. The subscription is really for more than one user.
Thanks for your help!
