home router battery backup

My current solution is having the UPS plugged into my bare metal fileserver. But I’m wanting to get rid of it at some point so any other solution will be superior to none. I appreciate the added info!

That being said my current router solution is a Ubiquity ER4. I don’t currently run openWRT on anything because my older server hardware wasn’t able to keep up with full 1gb up and down speeds with openwrt or any other flavor of self hosted routing. Not sure I could still apply your solution to an ER4.

Thank you,

I typically run the ups monitor off a suitable openwrt box (most have
at least one usb port) no need for a separate pi.

I tend also to hang a good gps off a second usb port, if available.
There's a topic for geeks - does anyone else really know (or care)
what time it really is?

I tried to build a better future, a few times:
