Variables are not showing up!

Just updated the app, and now I'm not getting any IO or variables in lists. It shows empty placeholders but no values. Look forward for a fix soon.

Super Easy!

Installed the app, and it automatically discovered the controller on the network. Within a minute or two I had a watch list with live values! Very simple to setup, without typing any addresses or tag names.

Just installed it

Does more than I expected...access to strategy variables is very cool...way to go Opto. We have 40+ controllers at customer sites, this will be very useful.
