It absolutely is, as long as there is an early adopter of tech as the homeowner. Some knowledge of networks and IoT devices is extremely helpful, but for the most part, once the system is installed, it just works. For a home, it's safe and adapts well to the significantly electronic environment. PoE Texas makes a PoE powered combination network jack and USB-C wall receptacle, so power and data are available for most modern electronic devices. Throw in some table lamps converted to DC using DC bulbs which could run off a PoE lighting node and it's a slam dunk.
Except you are trading a $20 circuit breaker for a $1000 PoE switch that should probably be replaced every 5-10 years because it will no longer be supported.
And if it's a Cisco, takes 10 minutes to boot up after a power failure.
I think you are probably looking at receptacles with a power supply that can supply a couple USB charging ports and inject power into POE jacks. I don't think there is any need for a POE switch. Just bring a data cable in and you can inject the power right there. No need for a POE switch somewhere.
But in exchange you're also trading heavy gauge copper, an electrician, and death for a system that runs devices more efficiently, safely, and longer with the ability to be actively monitored and adjusted. Plus I'm sure you have no qualms with replacing your multi-hundred dollar smart phone every couple years. A $1000 switch today will be $100 in ten years and more reliable, like everything else that's based in advancing technology. How long do you think it'll be before that $20 breaker is replaced by $100 breakers that can be remotely controlled? And how many breakers are in a modern panel, anyway?
You should check out something called a UPS. Besides, nobody would spec a Cisco switch for a home.And if it's a Cisco, takes 10 minutes to boot up after a power failure.
the whole point of POE is to use the existing stuff and not have to reinvent the wheel. it works pretty well as long as what you are powering is within the limited capability of the wiring.
I have not seen that at all. Just lighting mostly, and it is well suited for that, at least in residential settings.And that limited capacity is what is going to kill it. These guys want to power buildings off it.

You aren't just "technically incorrect". You're grossly incorrect. You have no idea what you're talking about yet you call yourself a technical advisor? LEDs are not resistive elements and you can't just hook up raw LED elements to a voltage source and be like voilà. A standard PoE power supply is a voltage source. You can't just hook up raw LED elements to a low impedance source. A current source power supply wouldn't be a standard PoE power supply. It would be an external LED ballast with an RJ45 connector.
UPSs exist and people buy them to mitigate the effects of a power outage. I'll bet in every instance they've checked to see if they'd rather use (or are allowed to use) a diesel generator that requires testing every month and decided a UPS is a better solution. What's your point?
Actually, network cabling IS powering entire commercial buildings, although the main power transfer method is not using a PoE standard.
On the face of it, that's a nonsensical idea, as the Class 2 rules limit the power to 100VA, as I understand them. Do they have any plausible argument otherwise? Are they trying to exploit some limited duration surge exemption in the listing standard for Class 2 devices, and then repeatedly pulsing the DC power above and below that 100VA limit?
Maybe they are running 100 VA in 30 conductors simutaneously.
