If you’re already running Pihole, I’d look at other things to do with the Pi.
https://www.adafruit.com/ has a bunch of sensors you can plug into the Pi, python libraries to make them work, and pretty good documentation/examples to get started. If you know a little python, it’s pretty easy to set up a simple web server just to poll those sensors and report their current values. Only slightly more complicated to set up cron jobs to log data to a database and a web page to make graphs.
It’s pretty straightforward to put https://www.home-assistant.io/ in a docker on a Pi. If you have your own local sensors, it will keep track of them, but it can also track data from external sources, like weather & air quality. There a bunch of inexpensive smart plugs ($20-ish) that will let you turn stuff on/off on a schedule or in response to sensor data.
IMO, Pi isn’t great for transport-intensive services like radarr or jellyfin, but, with a Usb HD/SSD might be an option.
Remember the Arab Spring? Massive protests in multiple North African countries, mostly peaceful regime changes. Those protests were hundreds of thousands of people - less than 1% of most country populations. Most of those nations were still going about their daily business like normal. Complaining about the awful government. Complaining about the disruption of the protests.
It’s really had to get people out of their daily routines.
In the US, there’s the extra issue that a significant part of the population are actually happy with recent events because they think it’s going to work out well for them, personally. Some of them think that the chaos is exactly the overthrow of 4 decades of terrible government they’ve been hoping for, and they don’t care what comes after.
