I do this except the offline copies are raspberry pis, they grab an update then turn their network card off and go black for about a month. Randomly they turn on the network card, pull a fresh copy and go black again. Safe from randomware and automatic.
I have a trailer (workshop) with solar power, batteries, a raspberry pi controlling everything and a cellular hot spot. It pumps all the solar, battery information and light controls over MQTT and home assistant over cellular. So yes its possible, what do you want to do?

Power is a measurement of the velocity and volume of water flowing through a pipe at a given instant*
I’m so sorry, I am officially ‘that guy’, taking a simple analogy and making it annoying…
My 16 year old Samsung TV would like to argue otherwise! It’s a beast and 1080p is plenty good for me! But my Samsung kitchen? Holy crap it’s all so terrible…
Shit I thought I was so damn novel. Blast you.
I’ve owned and deployed a lot of pi, every model, and in my experience when I have similar instability as you described its related to the sdcard. Either the sdcard itself or the tray soldered to the pi. I had one pi that would corrupt the sdcard without fail after 2 months and I played with bending the sdcard metal tray inward a little to help press the card better into the contacts and the problem went away. Try fiddling with the sdcard holder or different sdcards.
I’m almost 40 and now just realizing my insistence on how to structure all my folders and notes is actually an ISO standard. Way to go me.

Well incompetentboob, let me tell you. You will short and blow the voltage supply on the motherboard and take that port out of service.
Install Enocean wireless, battery free switches. I’ve used them for many years, they work awsome. The switches can go anywhere you want (double side tape on any surface) or screw in as normal light switches. The act of pushing the button generates enough energy to send the RF signal to a receiver you install with the light and its powered from AC mains.
It’s going to haunt you for years. Wife: “why doesn’t this iot thing work?” Oh its on the wrong network. “I don’t understand it just doesn’t work”. Then I go add more exceptions in pfsense and the cycle continues.
You haven’t worked with a lot of Chinese engineers, have you? https://www.chinaexpatsociety.com/culture/the-chabuduo-mindset
Perhaps not the same but I own a 150 year old home in America and I had foam insulation blown in. The insulation it provided was minor but what it helped tremendously with was drafts and air exchange. On older homes air leaks and sealing any cracks and drafts can potentially save you more money than adding actual insulation depending on how leaky it is. Food for thought though it might not help you.
I work on consumer electronic ear buds. Frigging ear buds, and we support this…
As someone who designs global battery powered products in the USA and is well versed in the regulatory hurdles, enforcing these rules is long overdue. The fact that people willingly buy and bring these illegitimate products into their home and wear them on their body is mind blowing to me. You can design a safe lithium products but doing it requires full knowledge of the chemistry, electrical design, safety certification process and some wisdom. Chinese vendors on Amazon have very little of this.
I went a little crazy and setup my own wireguard VPN network, all the remote hosts connect to the VPN and the primary server connects to each of them and pushes backups. Because I use btrfs and lots of snapshots I use btrbk, annoying to setup but now my hourly snapshots get pushed everywhere, minimal bandwidth and it flawlessly has worked for years.
