Little boxes, little boxes made of ticky tack
I couldn't help but be reminded of the old Pete Seeger song.

I can imagine a development full of this 'ticky tack' all using the same channels because the developers don't have a clue about setting things up correctly.
Oh wait... This is a dead as in six foot under idea already. As 99% of developers won't put in anything but the bare minimum of insulation etc and certainly no PV arrays because
1) it is too hard and they can't make Bog standard 'little boxes'
2) and might eat into their profits (or so they think)
3) UK homes are so small that the roof area is so tiny that a PV system will look ugly (to the punters) and not return any ROCI over 25 years. I've only seen one development (near Cheltenham Racecourse) where the PV system is built into the roof.
I like the idea and anyone building their own home (aka Grand Designs) will include stuff like this bot for us mere mortals? forget it.
Decent networking or battery storage? Not a chance.
