This should be possible. What attribute from the device with the WU driver are you hoping to use? (I don't use this and was hoping someone who did might respond, but I figured since it's been a while...) RM lets you create conditionals, which it sounds like what you want. If you aren't familiar with how to create or use those, Hubitat has a couple examples on their YouTube channel of how to create them, plus lots of examples in the docs of them in use.
The issue here would be the attribute. Can I assume that there is one that will work? If it's not a standard attribute (and I'm guessing it isn't), you can create a condition with a custom attribute in RM, so this should still be do-able. "Standard" attributes (like temperature, humidity, etc.) should all be usable as well in a more straight-forward fashion (not that different but just a few clicks less). If it it requires math or a look at historic values of that attribute, it would likely also be do-able but would take a bit more work.
If you share exactly what information from the device you plan to use, I could give more specifics, or maybe someone who actually uses the device could chime in.
