Currently remodeling a domicile, with the sweet and expensive ability to add anything I want within reason. I plan on modernizing the place to bring it into the 21st century because this house deserves it (just a great structure with lots of history and nearing it's centennial birthday).
Luckily, everything is built perfectly for access so nothing is off the table. I came onto this property with my own server "rack" and a mini diy setup for network debauchery, but plan on expanding that and installing a mini-server "room" (a fancy closet I might install in a "dead space" that I can pipe duct work in and out of).
I will be running all new electrical, A/C, Telecom lines, the whole works. I'm currently in the process of ripping out all the old coaxial, phone, piping, anything not ran properly or of a modern importance (probably reinstall phone and doorbell circuits but they're currently strewn everywhere from previous installers). I'm also creating up to date blueprints for the structure and including mechanical systems/engineering schematics for anything I'm doing or plan to do. All of this will be saved to a USB for the next owner and printed out for a laminated notebook to stay with the house (maybe a copy for myself for the nostalgia one day).
The only 2 things I KNOW I want to do is installing
-
a monitor with a pi that will run a weather and local data program that I've been working on into the kitchen area
-
a multi-camera cctv system (local and offsite backup) with a monitor in a neutral-shared living area.
I will probably leave those parts of the system installed here unless it's requested to be removed. I actually would love to leave everything here as a full system package for someone to "inherit" with the house but I'm not sure if that's a benefit or a hindrance someone wants to receive.
There's 3 different plans in the works (3/5/10 year plans, we are here for family but that will eventually not be required and we desperately want out of this area), depending on the time frame I might need to put in
-
monitoring stations for renewable energy systems (solar/wind),
-
a personalized-home weather monitoring system (barometric,temp,humidity) with a display and functionality to control the mechanical systems (A/C adjustment, daylight sensors for shades/lighting, etc),
and a bunch of other off the wall ideas I've been wanting to tinker with. Unfortunately most videos out there of "home setups" include someone with 10x my price bracket and their system is designed for themselves and their specific equipment in mind. I'm wanting to install something more generic that anyone would have use for (like weather and security). There are really only 2 "office areas" that I think would require a hardline besides any monitors I have to install for systems (I don't mind running wiring, but I don't think every room needs an ethernet port to be functional, or am I wrong thinking this way?). I will probably need to install repeaters in two locations though to cover the entire property in wifi because old houses gobble signals up but inside everything "just" reaches.
Everything I've done with my network so far I've gotten around needing a switch (it would've saved me a lot of hassle in the past but I usually find a way to get everything connected or just disconnect unused equipment that's ran it's course), but at this point I can't expand any further without a headache. So now I'm looking at new tech and equipment I don't have hands-on experience with and don't know it's proper use/limitations which I don't like when making action plans. I figured just trying to get a general sense of what people want or see would be a better angle to come at since I don't do this professionally and don't have the insider knowledge of the taboos of home networking infrastructure.
TLDR: What kind of wiring, connection setups are important to you and won't be obsolete after a few years? What do you consider a "modern" house to have or are decent "quality of life" improvements like lighting control, sensors, etc? What's your best case scenario of equipment when walking into a house and seeing a pre-installed setup?
edit: I'm not sure why but for some reason I'm not seeing everyone's comments (assuming de-federated instances from .ml but seeing it since I posted on .world), if I don't respond I apologize and will probably look for a new instance if this is the case.
If you're running ducting into your server/switch cabinet I've thought before that it could be interesting to have an exhaust setup that you can switch between venting the excess heat directly outside (in summer) or back into the main house (in winter).
The only problem with that is if you're pumping air out you have to think about where the air is coming in from. Older fireplaces are notorious for this because any air escaping through the chimney has to be replaced usually resulting in the rest of the house becoming actually colder through air gaps/cracks. Newer built houses even have ductwork for controlled air introduction when using exhaust fans like the range hood over the stove to maintain relative pressures with energy efficient houses (this house is nowhere near that level yet, but once newer windows are installed and I can seal the outlets I replace/install it will be one step closer).
One thought I did have is running the HVAC return through the area, it would reduce the relative humidity of the house as I've already installed several dehumidifiers for the closed crawl spaces I've sealed up and insulated but this whole geographical area is just horrible (/s about the servers being a dehumidifier, but realistically the equipment has to have some type of impact even if 1% lol) . Nearly every house I've worked on has some type of moisture issue but home owners typically don't care unless it becomes life-threatening or threatens the structure. My thoughts on the return is so cold air isn't directly blasted into the area as the dramatic temperature change might introduce condensation, the calculations for the CFM (airflow) have to be exact though so I'm not killing any systems early. The house has an old A/C system with an oil heating system (also has propane and electrical heating in other locations, idk if the person before me had a thing for collecting all the systems but it's rather insane), the a/c doesn't cover the entire structure though so I either have to think about replacing the entire setup (it is rather old but looks well maintained surprisingly) or milking the old system while installing a secondary hvac system for the unconditioned areas (mainly 2nd floor, plenty of attic space to install it which will probably be sealed as well if I do).
You definitely hit on a great idea though, I was planning on installing a secondary thermostat in the server area. If I did a return through and set it to active the hvac system fan when a temperature threshold is reached, in the winter it would disperse the heat through the house and I wouldn't have to worry about the system switching from A/C to Heat or how I would continue to cool an area now getting hot air directly pumped into it. Then in the summer the air returning would be directly cooled when necessary and released back into the house so I'm not worrying about another outside vent opening requiring filters that need to be replaced/inspected etc. Might be able to pull off the airflow requirements with something as simple as a slotted closet door a lot of bedrooms have. I would be concerned someone might replace the door one day without realizing it's importance so maybe dedicated wall venting into the server area is safer, even if it looked worse.
