…(it is kinda like a bomb after all)…

WAT? I’ve never heard a UPS referred to as “kinda like a bomb” before.

Keep your UPS maintained, replace the batteries when they age out, and it will be fine. If your UPS supports automated self-tests, use them.

My employer has UPS units spread all over the region we operate in, and we don’t have any issues, despite leaving them mostly unattended for years. I have several in my house and I’ve never given them a second thought aside from battery replacements.

Man, I don’t even run my desktops without a UPS. Maybe I’m jaded from too much tech support, but I feel like not having a UPS is like not using a condom for a random hookup: it’s fine until it dramatically and seriously isn’t.

Almost every desk at my workplace has its own lead-acid battery. That’s well over 1000. We haven’t had any fires or explosions.

The device you’re thinking of has 42 decibels of sound. You should be aware of that, I don’t think it’s actually fanless

Noise is going to be a huge factor for your home lab, so make sure you look at the data sheet for whatever you’re about to buy and check what it’s rated noise level is

You want the ability to remote power cycle everything and to get a quick status. Get a single board computer and use it as a jumping off point. From there you can go get some smart plugs that can be connected to the single board computer.

Always UPS everything. But also always have a simple backdoor. I generally have 1 little desktop like a NUC running some basic Win10 OS and an install of remote software like TeamViewer. It is connected to my hardware router right after the ISP router and a backup connection. Used to be LTE everywhere, now I’m half and half on Starlink. It is then also connected to the router ports needed for management but inactive.

If I have to, remote into the NUC over Starlink. I can then reboot my main ISP box. I can eventually get into my router and enable those ports which are pre-plugged in. From there I can then access all the stack management and all the IPMI ports like iLo. It’s a virtual interface through a virtual interface. It is slow, and painful. But it works.

And it works 99.99% of the time. But even then, I’ve had to do a call of shame and walk one of my friends through which button to press as I’m on the other side of the world. In my case it was also power related but the UPS I had decided to overheat. In reality over the summer, the temps were high. But also it is a super awesome double conversion UPS. The line voltage into the UPS was dropped to below standards from the utility because their grid was overworked with everyone’s AC’s. So the UPS saw this as a line failure, kicked in the double conversion and ran happily. But it did not count as a power failure, so none of my services scaled back. Essentially it was delivering 3KW of juice from the wall through a double conversion making the whole thing super hot. Eventually it shut down for safety automatically, just pulled the plug. My NUC is on a separate little backup along with the modems and an auto transfer switch which did its thing. But there was no way to press the reset button on the UPS for a critical safety shutdown like that. It had to be in person.

Line interactive basically means the battery will always be feeding the devices on UPS. Make sure you don’t go over the listed wattage. I learned the hard way and bought an under spec Tripplite, the battery kept dying. I now have a UPS specced out for my router and the Verizon box outside, not anything else on my rack. You should be fine, just saying in the future when you add devices, keep that in mind.
