Our new house has a fancy ADT alarm system that will shout out, if you want it to, when anyone opens a door. Presumably before this went in, the house also was equipped with an elaborate door alarm system for all of the doors leading to the back yard and pool. This would alert people in the house that, for example, a toddler was in danger of falling into the pool.
I’m not sure that the door sensors work anymore and, given that we have the elaborate ADT system, I don’t know why we would ever need these door/pool alarms.
We have four of these cluttering the walls of the house. Does anyone have a brilliant idea for what to do with a network of 1-gang boxes that are fed with 12V? There is no CAT 5 wire to the boxes.

The lion kingdom has a wall clock, musical instrument, lighting, audio amplifiers, ethernet switches, battery charger, all running on 12V wall warts. The wall warts burn at least $1000 of rent every year so there’s a definite use for 12V outlets. Not sure how a PhD in EE with no knowledge of electronics would accomplish a conversion from wall warts to outlets though.
Unfortunately, they probably don’t provide any reasonable amperage, but if they do, you can find your local neon tube artist and make some custom house art. Powered by: https://www.amazing1.com/neon-transformers-12v.html
Could you use the 12V wire to pull Cat5+ cable? Perhaps with an intermediate step of something like nylon?

Was the house built before they invented mechanized pool covers? Also useful for preventing all the debris blown on the ground from getting into the pool.
The house and pool are from 2003, so pool covers existed then. Everyone here has a pool and I haven’t seen any covers so far. I don’t know why they’re not popular. Our yard has a couple of magnolia trees that shed heavily. If we had a cover, though, I think we would first have to remove the leaves from the cover before retracting it, no?
https://www.poolspanews.com/how-to/pool-covers-covering-the-bases_o says “two strong pool states — Florida and Arizona — have been cover laggards, making up only 5 percent of the market”
One thing that seems popular, though, is a screen enclosure around at least part of the patio and all of the pool. I think they are ugly, but people love them for keeping debris out of the pool and insects away (the bug season seems to be June-August and is nowhere near as bad as in Massachusetts).
I have a cover over my pool. Outside pool itself is rather useless in Seattle most of the time, but cover is a god-send: otherwise I would have to clean the pool and filters all the time. On a flip side it deteriorates and every 4-5 years needs replacement. It was around $3500 last time, and now it needs to be replaced again. I can’t image how much is it going to be in today’s mini-dollars. In Florida’s sun covers probably need replacement more often.
No sure if a pool cover is sufficient by itself. I think there is a law in FL making some sort of pool alarm system obligatory regardless of the pool cover installation.

One of the good things from our big hurricane was moving away from the 16×32 pool and the stumps of the magnolia trees. One of them survived with no leaves but I cut it down just for spite – what horrible trees! When we had toddler grandchildren, they wore wrist alarms with a link to the indoors. Our daughter’s friend lost a child in their pool.
