After meaning to for years, I finally installed NUT (Network UPS Tool) for my UPS.
It took my while because I wanted an independent device to run it that wasn’t mixed up with other servers running virtual machines and containers.
After researching low power devices, I bought a used HP T620 off eBay for $20. I really wanted a Raspberry Pi, but the prices are outragous nowadays and I didn’t want to cobble together all the parts.
I ran into a minor issue configuring NUT, but overall I’m happy with the setup.
