Before doing anything, please back up that HDD. Clunking but working means "back up now, I could die any second"

I can't call it read-only friday, I'm doing site maintenance at lunchtime!

Don't give them ideas!

It's like someone with no taste had to fit out the house, and had a £3000 gift card for The Range.

WMK values are generally quoted as transmission for 1m thick for insulating materials. (watts lost per meter squared per delta kelvin).

For example, PIR board is about 0.022. So for 100mm thick, it would be 0.22W lost per degree difference.
The aerogel glass is quoted at 0.053
Mineral wool is 0.038
Brick is 0.600 on a good day.
Pure aerogel is about 0.018.
Glass is about 1.000 (varies).

I can see this being used in situations where light is needed, but a window is not.
I can definitely see the benefits of making utility walls out of it.
It's going to be expensive though, at least until aerogel prices come down.
And it's not going to beat using the same depth of PIR board, or mineral wool. (assuming the numbers are all correct)

This is my eventual goal. I want the house to be automated to the point that the only interaction I have, is just living.

If I walk into a room, the system takes into account the time of day, day of week, outside light level, and brings the lights up.

If it's really cold outside, it raises the radiator flow temperature. If only I'm at home, and it's a monday morning, it only raises the temperature in the bathroom, kitchen, and my office. That kinda stuff.

I always find it a bit amusing when I see "shut down due to radar activity" in my 5GHz logs.

If I got an alarm every time a 433 sensor didn't check in for 10 minutes, I'd never get any sleep!

Yep. With the solid walls I have, if you're not chasing into the plaster/brick, you're putting trunking on the outside (which looks pretty awful, imho).

2.4GHz wifi is vulnerable to even lower power attacks: Just spamming de-auth packets is enough to render a network useless.
