Outside of a closet, I have a Jasco dimmer switch installed
According to Vera, it’s capabilities are: 211,156,0,4,17,1,L,R,B,RS,|38:1,39,112,114,134,
and the version is: 6,3,40,3,28
Anyway, I have the it set up with a 3-way switch (not sure if my terminology is correct)
When I flick the switch up on the main light switch, I have a trigger that runs and my closet light goes on, however, when I use the slave device, no such action occurs
Are slave switches able to send these signals or did I perhaps set up the switch wrong?
What you are seeing is normal and proper operation.
In order for your trigger to work in a timely fashion, the dimmer needs a feature called Instant Status to immediately inform Vera when it is switched. Without Instant Status, Vera will be unaware of changes at the dimmer, until Vera polls the dimmer, which can take many seconds or even minutes.
The Jasco dimmer issues a Z-Wave broadcast(Network Information Frame(NIF)) when it is pressed. The NIF is used for include/exclude operations. When Vera is not in include/exclude mode it interprets the NIF as a status update and your trigger is activated. In this case it is a pseudo Instant Status.
When the remote switch, what you called the slave, is touched it does not cause the main switch to send the NIF. That’s because include/exclude operations can only be performed at the main switch, not the remote. Without the NIF Vera does not see the dimmer change and your trigger does not activate the scene, until later when Vera polls the dimmer.
In order to make the triggered scene work the way that you desire, you will need to replace the dimmer with one that supports the Instant Status feature.
Switches that support true Instant Status will activate the trigger the instant that the switch changes state. It will not matter what caused the state change, main switch, remote/slave switch, remote control… If the state changes, the switch will pass it on, a status update is sent.
