Pi-hole + PiVpn works wonderful (if you can find a rpi that is... ). Been using that setup for a couple of years, very stable.

It's just software, you can install it on any server. No need to limit yourself to (currently?) overpriced Pis.

Sure, but a pi consumes about 3.5W of energy and can run 24/7/365.

There are alternatives, but most other solutions will end up costing more in electricity costs. Especially problematic in say Europe right now.

Are you sure about the 3.5W? That seems high. An iPad at idle with the display on uses less than that.

I use RPi 3B because of lower power consumption than 3B+, 4B... It is around 300mA. I connect power cable to USB from router that has 500mA output. It works great.

RPi 3B+ has sometimes problem with stability because of higher power consumption.

Official power supply of RPi is 2,6A if I remember correctly, so 3,5 is not even possible?

Btw, many routers support sleep mode. It is not necessary to run router/connected RPi 24/7.

Watts vs. current.

At 300mA, that's 1.5W of power.

Maximum current draw on a pi4 is 3A (~15W), but that's purely a power supply input limitation. You only get close to that with a ton of peripherals and heavy load on the Pi.

Ah, yes, sorry, my mistake.

About 3W is realistic for a Pi 4. Here's a comparison:

If you already have an always-on computer (NAS, router, etc), installing it there is likely to increase your electric bill less than running a raspberry pi.

You don't need to use the more power-hungry RasPis, either - PiHole works great on Zero W.

NextDNS + DNS-over-HTTPS works really really well. Super happy with NextDNS.

NextDNS is great. Totally worth the $

I use wireguard + adguard home. Both docker containers (in a docker-compose.yaml), easy to set adguard as the dns resolver for any wireguard connection. It runs from my basement.

I also hear great things about TailScale, will also try that (soon I'll be "forced" off my fiber/fixed-ip connection).

AdGuard Home really is great. One really doesn’t need to set up docker if they don’t want, since it’s a single self-contained binary.

Indeed, I hear that some people even run in on their EdgeRouterX (Debian afaik) for example.

But I also ave Traefik in the same docker-compose file for DNS and certs :) (currently still wrestling with the ports and certs for stuff within my lan though.)

Seconded. Yeah, I've been using PiHole in a Docker container and accessing it over persistent Wireguard tunel for some time. It's been great. That and access to all of my services without them being exposed to the outside world.

I run Adguard Home on my router.

Even though the name implies you need to run it on a raspberry pi, that's not true.

Same here. It’s incredibly simple to set up and add exclusions and inclusions.

> if you can find a rpi that is...

I'm out of the loop, is there a rpi shortage?

Yes, constrained supply means individual customers are going to struggle to find stock.

I was shopping for 2 8GB models a few months ago. There is / was a shortage and some shops / resellers charge 200-300% above list price. Highest I’ve seen was 350€. This was the German market, but from what I heard it doesn’t seem to look a lot better globally.

Kinda the same way that there was a GPU shortage up until recently. You can go out and order an rPi now and it will get delivered within a week, but the markup is insane. It's basically impossible to find any Pi hardware at MSRP.

Chips in general are still experiencing supply chain issues too, so this is unlikely to change.

And on the road?

I guess with PiVPN you don't need to worry about that?

I wireguard home in order to get PiHole filtered internet on the road.

I also use PiHole from a docker container on the same server that's running wireguard.
