This is probably a pipe dream because there's too many different types of devices by different manufacturers in vastly different form factors but it just feels bad having say a modem, a router and a switch and therefore having three crappy low(ish) efficiency power supplies.

I mean, in a lot of parts of the world, outlets in a bathroom are against the building code. https://www.electricalsafetyfirst.org.uk/guidance/safety-around-the-home/bathroom-safety/ Or I guess not fully, but they do have to be at least 3m (10') from the bath and shower, so it'd have to be a gigantic bathroom to be able to have an outlet.

Ironically, I have never tripped a GFI with water, only hair dryers. I refuse to use GFCI because God acronyms never have more than three letters. Great acronyms have a cool sounding name too, like RAM.

I optimized my network rack (ok, it's a table) by using an old computer (ATX) power supply. Most of these networking/IOT devices use either 12 or 5 volts, so you can clip the wall-wart off the cord and attach the wires to the correct (red=5, yellow=12) supply lines from the power supply. I'm feeding like 9 different devices off one power supply. Another bonus to this is that computer power supplies are more efficient and produce much cleaner power than those wall warts. A common failure point for that equipment is a crappy power brick that over-volts or under-volts the device until it lets the smoke out. Nothing like a $250 router getting smoked due to the lovely $0.50 power supply included with it.

Lead out in cuffs posted:I mean, in a lot of parts of the world, outlets in a bathroom are against the building code. Here in Sweden it started out with being completely banned, then in the 1960s you were allowed to have an outlet dedicated to a washing machine, at least 170cm above the floor level, as well as a 110 volt outlet that was intended for electric shavers. Finally in 1996 you could put in a regular 230V outlet for hair dryers and poo poo, as long as you have it on a ground fault interrupt circuit. You can still find plenty of houses featuring bathrooms with just the 110V outlet, which can be cause for confusion.

What's the weird thing underneath the suicide door with the blue line wrapped around it? My guess is that this suicide door is really high up and that's actually the mounting point for a hoist for another suicide door on the next level down, but that doesn't explain the blue line.

Just finally caught up after slowly reading through the thread for what feels like a significant chunk of my life. To contribute - some insane electrical fuckery that I had to deal with when I moved into my house. I brought my house about 17 years ago, but I'd known it a lot longer as it was a friend's childhood home. I also knew that they had some weird habits about not turning the lights on until certain times which I assumed was down to them being cheap, and I knew that his grandmother was as deaf as a post so they had a doorbell that sounded like an air raid siren and some lights that flashed when you rang it. Turns out that wasn't the full story. They had a contraption hooked up next to the fuse box that connected to the doorbell. The lighting mains power ran through this device, and if you rang the door bell some kind of large coil would reduce the power to the entire lighting wiring and cause all of the lights in the house to briefly dim for three short bursts (as well as playing a horrendous "EEE-WOOO!!" noise out of the speaker from hell three times). Ok, I kinda get the idea as it means deaf grandmother would see the lights flicker and know someone was at the door. But... did that mean leaving the lights on the whole time? Yes. Yes it did. Ah, but to counter this there was a light sensor on a wall outside with a cable botched through to the same weird contraption. If the light level was still daytime, the lighting was simply disconnected. You'd flick the light switch and nothing would come on. Thou shalt not have light until it hath gotten dark out. Although if you rang the doorbell, power would now be restored to the lights for the duration of the "EEE-WOOO!", meaning the lights would now flash all over the house. Once it got dark enough for the light sensor to switch over, all of the internal lights would suddenly come on in the house and we were now back to the dimming doorbell. This explains why I would be at the house as a kid and wonder why they always lived in this weird twilight before turning on all of the lights in the house at once. Or why lights would randomly turn on and off during heavy storms. To make things more interesting, this house has concrete floors upstairs. This means no floorboards, no easy conduits and 1950s wiring buried in the concrete. Any alternations were done by spurring off from existing sockets or (as I found out), running mains sockets down from the lights. Note that this is the UK with 240v. His sister lived in an "attic conversion" that it turns out had it's sockets and lights connected to the back of a single light. Then from that, other sockets had been wired around the house daisy chained off that. And of course, if you rang the door bell you had every electrical device plugged into this circuit of the damned suddenly dip in power. Running a computer up there? EEE-WOOOO! Computer just rebooted because the pizza guy rang the doorbell. As a kid I'd visit my buddy and we had a small shed at the bottom of the garden (mid 1990s) where we had our gaming PCs (with big old CRT monitors) and a space heater for LAN coop play. Turns out we were running all of that over a single cable that ran from the garden up into the roof and then connected to the back of a light switch in the deadly attic conversion. When I ripped it all out it turned out that they'd run short of cable and made up the difference with motherfucking speaker wire. The house had old fashioned storage heaters (lovely system that runs overnight and heats up large, heavy ceramic bricks that stay hot throughout the next day - terrible system). This meant my power was an "economy 7" tarif, meaning cheap as dirt power in the night to charge the heaters but then more expensive during the day. Naturally the genius that devised the doorbell from hell decided to restrict certain outlets to only come on out of hours (so your tumble dryer and washing machine would come on in the night when it was cheap). I've found open, live cables plastered into walls. I've found spotlights running over speaker cable. Turns out the shower power chord was wired up wrong and basically did nothing but smoulder away up in the attic nestled among the old newspapers used for insulation. I found a shelf with a screw going through the thick mains cable that used to run to the oven (before they had gas, so it was a single fuse just for running an oven). They'd never figured out what was constantly tripping the RCD, so they simply bonded the RCD switch in place so it couldn't trip. Meanwhile, my buddy who grew up there found it strange that he didn't have to "leave the big lights on" and didn't have to do his laundry at night. He also now knows how close we all came to dying..
