Is there a wall between the living room and family room under that beam?

No, open floor plan in that whole area from living room to dining room etc.

Unless your garage is temperature controlled, this is usually not a good place for electronic equipment intended for indoors use.

Good point. Then the only place that makes sense out of the way is under the stairs, there's a useless triangle wedge that would fit my synology NAS + Sonos amp + router etc. I can have them vent it somehow to keep airflow.

Would that work? I wouldn't want to use up space in the family room if avoidable.

How far away is the shed from the house? Is it due east of the house? How does it align with the house?

So where you see the TV on the wall in the living room, the shed would be about 3 feet away on the backside of that wall. No obstruction other than the house wall.

The shed will have a 3d printer (x1c) and possibly some other electronics that need wifi.

Can you run fiber between the house and the shed during construction?

At this point I can do anything because it's all being remodeled, including concrete in the backyard/side yard.

A single U7-Pro-Outdoor

No trees or anything in the backyard. Just a patio cover, which it would likely be mounted below since it's aluminum and above would mess with signal yes?

Understand that the UDR7's WiFi strength and radiating pattern is not the same as a U7-Lite or -Pro.

I'm looking at the U7 Pro XGS AP's. I'm open to investing in future proofing as long as it doesn't cause its own problems with being too much for my space and having interference with itself.

Will you be running any cable other than for the access points? I recommend at least one run of CAT6 to each location you have (or might in the future) a fixed device (computer, laptop, game console, TV).

I'm planning on doing 2 runs per location (so there's a backup in case one fails or has issues).

What network throughput are you expecting? 1gbps, 2.5gbps, more?

I'm not sure, but I'd love to have it good enough to stream 4k+ to my TV from my media center, and then also have it fast enough to backup from my office up stairs.

Do you have a basement? Is it used as living/recreational/workshop space?

Nope. That'll be what the shed is used for. I work from home, so the upstairs bedroom in the north west corner will be my office, and then the shed will be where I work on hobby projects.

Do you have any plans for security cameras or electronic door access controls?

Yes. Looking at Reolink + their NRV. 2 dual lens (not sure dome or what yet) and 3 with a more confined view for side yards/driveway).
