I keep thinking about a future retirement business: a mom and pop electronics hardware store, stocking the widest variety of maker goodies and serious bench tools, the kind that are very much try before you buy, if a private buyer - in my ideal world - and my USP would be providing a RPi distro I'll while away my final years polishing the autoconfig for all the home automation kit I can manage to disconnect from the cloud. EDITED REMOVING A REVERIE TO MY PROFILE, my apologies, often carried away when I'm enjoying the topics here, it's not my wish to spoil the flow as I almost did. This said, I will surely be delighted to hear from anyone regarding my rather wistful wishes, to which I applied months of health enforced downtime last year. I still think the qualified opportunity isn't a total wash and would be willing to invest in a no tears no recriminations study, later in the year. About the necessity of a WAN and firmware etc updating your home automation system: are we not in cities now at sufficient density where peer to peer hops in a as hoc network, has become a technical possibility that maybe lacks a sufficient motivation?
