I don’t have experience with UPS daughter boards for Raspberry Pis, but wrote this guide for installing a standalone UPS with a USB port.

Beginner's Guide to Network UPS Tools (NUT) on a Raspberry Pi

UPDATE (February 15, 2022): Updated with instructions for adding a second UPS Since I don’t want my OH installation to be corrupted by a power failure, I purchased a CyberPower UPS, and connected it to my Raspberry Pi using Network UPS Tools (NUT). There are various topics in the community about NUT, and this one was the most helpful for my purposes. With everything I’ve learned, here are some instructions to help others get started. Note that this guide is for is a simple setup with the UP…

I would recommend a CyberPower UPS, only because I know for certain that they work. But really, you just need any UPS that has a USB port and is known to work with Network UPS Tools. AmazonBasics is now selling units that appear to be rebranded CyberPowers. I ordered one recently, but haven’t received it yet.

I have my RPi, modem, and router all on the UPS, so that OH can notify me if there’s an outage (since it will still have Internet access). It only runs for about 10 minutes before shutting down the RPi, but that’s enough to cover most brief outages.
