I would <i>think</i> you&#x27;d want one central hub to effectively control the whole home. That makes sense to me. Like a thin UI wrapper to control EVERYTHING displayed on an LCD panel... in the living room(?). This makes sense because your selling point is a turn-key home. It would stand to reason that if the hardware is turn-key, the software should be too.<p>Bringing this all under one central control hub would probably take an equal stakeholder in your business. It&#x27;s just as important as the material aspect of the home. If you don&#x27;t have the wherewithal for this, you should probably avoid doing ANY kind of fancy electronic stuff. I know the PV panels are a non-negotiable... but I would suggest not going beyond that until you can create an SDK. This manages expectations, and paves a sane &quot;upgrade&quot; path for the hardware. Simple is always better than fancy.
