Good to have another Vizia user in forum.
1.Through the Web UI You should be able to go to Setup ->Advanced-> Logs
Check “Verbose Logging”
Then Click the “Show Z-Wave Jobs”
You’ll have to know what node number the sensor is device is.
Have you tried testing the scene by manually activating it in Vera?
I had a related problem, Since I can’t order the way lights come on in a scene, I tried making scenes with individual devices, and have one scene trigger the next. Vera allows it as an option in the drop down box, but I have yet to get it to work. I’ve posted to the forum with little luck, so I hope a future firmware upgrade fixes it.
Here is the wiki link for the Vizia 4 button controller
It is possible to let the Vizia controller activate Vera Scenes, but with some exceptions. I’m pretty sure Vera has to be the Primary(Not sure on this one though), or at least has to be added to the network by the Vera (Not sure if possible).
I migrated to Vera as the primary to support the Schlage Lock and I toyed with the 4 button controller, but was disappointed with how scene control works with the 4 button controller.
Pros: Easy programming and linking of scenes, you can now activate scenes with devices other than scene capable devices like arming sensors and thermostat control. It accomplishes this by treating scenes as events.
Cons: You suffer the popcorn effect where devices pop on in an order you can’t easily control. I’ve gotten used to the elegant Leviton solution where all the lights come on or off in unison in a dramatic fashion. I chose to program the scenes with the Leviton controller since I have no current desire to control devices other than lights with my 4 button controller.
Here is a thread to some of my experiences
