Not only that depending on how old you might get something much more powerful in a little fanless case that uses way less power. Especially if ARM architecture. Though there are decent Intel chips targeted t this market.

How power hungry is that old PC, though?
There are about a zillion options many/most smart switch lines have a battery remote that can typically be paired with any load(s).
The classic OG is Insteon. Their mini-remote screws to the wall surface and add a screwless Decora frame I think it comes-with?) is indistinguishable from a standard Decora switch.
I’ve even mounted one next to a single-gang box and put a two-gang screwless plate over it.
But you got those weird Aussie switches or something and Insteon isn’t popular any more, though the company got saved by then skin of it’s teeth.
Sonoff Zigbee dongle.
So OP comfortable with phoning-home to China though.
Cause they believe in some conspiracy theory.
Because Zigbee, Zwave, BLE, and various proprietary RF data transmission schemes aren’t WiFi.
Are you sure the unnamed devices weren’t using Ethernet?
Didn’t you have in-wall devices for this?
Wait’ll you see the version from Temu!
“Chinese version from Ali” prolly means somebody slipped the plans to their cousin at another factory.
They did the best they could and used the parts they could buy the cheapest.

These are “interconnected” using RF which is now acceptable by code at least it’s when I checked with San Diego Fire Marshall. But YMMV. SD has interconnect (only within each apartment) and dual-power requirement in high-rise dwellings.
If there’s an interconnect dongle for old hardwire-connect detectors, you’d find it on/linked from above link.
They all have a 10 year mandated lifetime anyway. Maybe just replace all now?
Getting notified is nice.
Getting the FD notified is nicer.

You don’t need to power everything in an emergency.
But if you get your heating and cooking with electricity and you’re in an environment that NEEDS cooling…
I use 10kwh/day average. But that includes power-hungry “steam” washer/dryer and dishwasher, none of which I need for a few days outage.
I’m lucky to have gas water heater and gas steam boiler. The boiler needs about 10 watts on standby and max 25 operating (ecobee, damper, auto-fill, etc.)
I’ve already rigged it with a cord and if there’s an emergency I put it on a little 300W/400 WH Jackery over night (will run it for close to a day) so I don’t have to run a generator. I plan on rigging up some kind of UPS with a few days capacity though.
I just bought a 1000W/1kWh gently-used Jackery for $450 from a neighbor who upgraded to a 2000Plus. That’ll run the fridge over night.
The Jackeries have great general utility and are both very portable.
Just got a 3000W 120V portable generator and that’s all I need for everything else. Stove top is gas, takes a match or lighter. Oven is electric I don’t need to bake cookies during an outage. Air fryer, toaster, microwave are fine on the generator, one at a time.
I’d eventually like one of those expandable battery systems with a 10 circuit automatic switch and load-shift during peak hours. The prices are coming down rapidly. Ecoflow looks good but plenty of competition coming.
