Hi, @Ryan780. I'm of course not under the impression that this is an opinion, rather than a fact. Yes, I have read the posts described above, among others; I note that several examples are discussed of devices that are Z-Wave Plus but that require the non-smart version of the system driver because the devices do not otherwise report their status updates. I wasn't aware that this behavior is unintended (i.e., means the "smart" version of the driver just hasn't been updated for these devices). I went ahead and requested review of the driver for the Z-Wave Plus Leviton device in another thread so that it will work with the "smart" version of the driver.
EDIT: In case helpful for someone referencing this thread in the future, the author of the drivers describes the actual distinction among the Generic Z-Wave Dimmer, Generic Z-Wave Smart Dimmer, and Generic Z-Wave CentralScene Dimmer here: Can't get Leviton Dimmer Module to Dim - #26 by mike.maxwell
