So, as I understand the Z-Wave Plus backwards compatibility requirements cover communication between Z-Wave Plus and original Z-Wave devices. Personally, I specifically take "devices" as the IoT term for sensors and other IoT objects.
My question is whether or not the backwards compatibility also applies to a Hub or controller (specifically the SmartThings Hub v1)?
I found this post to be slightly confusing, stating 1) that you need the controller to be Z-Wave Plus, but 2) you won't get all of the advantages. Ultimately, I have not found a source definitively saying Yes or No to whether the v1 hub (original Z-Wave) can control a Z-Wave Plus device.
