I have a ton of UPSs and never had any "fire-related" issues. But on the other hand I've also had a lot of UPS that fail, so sometimes it is the UPS itself that causes a problem, even when there is no outage. Also, they tend to run out of energy in the face of an extended outage, so you often need a generator backup that you can switch to. So if power is normally stable where you're at, a UPS probably won't help much anyways.
Oh, one other idea is to use a laptop. They have "built-in" UPSs and those are very reliable.
Yeah, I was thinking about that as well. Too bad Mini PCs don't come with some small battery like laptops. So if an external laptop could be made to power the Mini PC, it could work. Even some broken laptop that can just be used for charging.
I imagine this takes 12 volts or something like that. So you could diy a 12v UPS with some li-ion batteries. I have seen some ups kits.
You are absolutely right.👍
In addition to running the HIVE witness node on the VPS, I also run a local node on a Linux host at home. In order to avoid sudden power outages at home, I configured a UPS for the host at home. At the beginning, the host at home was very stable. But after three or two years, the host had power outages from time to time, which often caused my local node to crash. After careful investigation and analysis, I found that the culprit was the UPS. After I unplugged the UPS, the local node has been running stably.😅
Oh, good to learn from your experience, thanks for sharing. Some others mentioned similar reports that the UPS itself was causing power failures.
