I have a simple question regarding z-wave. Do I need a master controller (eg. Intermatic HA07) as well as a USB controller (eg. Intermatic HA22), or can I just get away with using the USB controller?
I'm able to control a light using just the HA22 and the supplied Windows software, but can't fugure out how I'm meant to add devices to the network within LMCE.
You need both. You 'add' devices or include them to the master controller and then you copy this data to the USB controller attached to the Core. Once the Core has this data then it can communicate with any ZWave device that is aprt of the network.
All the best
