Post getting an electrician to install C-Bus, what's the minimum post install requirements in terms of hardware software for (a) reprogramming any switches, (b) setting up schedules, (c) setting up any scenes/triggers? Thinking I would get a Wiser 2 as part of the install but was wondering what else is needed beyond that - keen not to have to call out an electrician every time a change is made. I'm fairly comfortable with the technical learning curve, more a function of what exactly I need to ensure is installed/purchase at install time.
