Hey guys. So I'd like some input. I have a few nodes, running a pi 3, each node has its own pi. I am running ASL3 on everything. So, here's my problem, a bunch of them are plugged in to a USB hub. Here's my issue, whenever the power goes out around here, these things are a nightmare to get back and running.
I've got 1 node now that won't even respond to anything. The pi comes back up, but that's about it. Curious how you guys are powering your pies. I'd like to find a solution that is reliable so I don't have to deal with this nonsense every time the power goes out. I would hope these nodes would just come back. It seems like I always have to plug and un-plug before they start running again. Sometimes it takes several cycles, and that should not happen. Any words of wisdom would be great.

You must have a power supply that can keep up with all the current or it runs hot and possible corruptions to disk and memory for multiple reasons.

Here is what I use. 5V 10amp
Don't forget every peripheral you plug in uses more current. It's not just the Pi.

I use a 24 port usb power supply max output of 10A . But first some decisions are they going to all be operated at the same location or spread out? If you have a USB HUB it may barely be able to operate all of your devices that creats an issue. You need to know how much currend your devices draw. And make sure you have enough current to power everytging that is connected plus about a 50% head room. You cant run everything against at max output of the power supply. Then you should be able to find for cheap an old computer backup or a UPS and buy it cheap and replace the battery. And plug your power supply into it. That should make your computers "nodes" happy and run more stable.

When you say "hub" are you really meaning a multi-port USB power block? Those are not reliable for powering multiple Pis. You'll have problems with the on-boot inrush current. They're also limited to 2.4A usually and that's a "spool up" process.

Seconded the UPS recommendation. I have had a couple of Raspberry Pi's never work again after quick power cuts when not getting power from an uninterruptable source.
I particularly like Cyberpower stuff. I've had too many APC inverter failures to recommend them anymore, especially the smaller stuff. Maybe they've gotten better since 15 years ago.

There is also the idea of running everything on a 12-volt system with buck converters for 5v operation, but that can get complicated, and potentially very noisy, especially with lots of nodes in the same place.
