Creating a toggle favorite for a variable

[webminster]

I'd like to create a favorite that can enable/disable a behavior, using a state variable.  Swear I had this work before, but now I can't replicate it.

What I've tried to do in UD Mobile is to create a favorite from a state variable I have in IoX.  I'm using that variable as a condition to enable a program folder.  I've tried to change the properties of that node's View Type to "switch", as I'd like to create some sort of toggle.

What I've seen doing this is that the switch toggle then flips the value of the state variable between -2 and +2 (depending on precision - higher precision shows like -2.14 and 2.14 for instance).  I also note that the toggling isn't completely deterministic - sometimes the state of the toggle doesn't correspond to the numeric value, as in toggling the switch from 2 (on) to -2 (off) shows the switch graphic go to off, then back on, even if the value is -2.

I assume this isn't a supported way to control a state variable, but is there some way to create such an effect?  Thanks in advance.

See the custom toggle example https://wiki.universal-devices.com/index.php?title=UD_Mobile#Favorite_Custom_Toggle

In short the Display Node and the Command do not need to be related, but the command should cause the Display Node to change.  The command should be a Program Run IF so it holds all logic related to the toggle.

Thanks, that's helpful, got it working.  The note about the variable/program startup refresh was good.
