    How would this perform as a plex server?

    EDIT: not good

    • +6 votes

      I wouldn't recommend it. I use a Pi Zero W as a RasPlex client and even streaming media off my home server it isn't an overly smooth experience. I don't imagine it would be any better if it had to manage media files as well.

      Its great for pihole. Plex server no way

      •  

        I was thinking of running Pihole using this too but then I learned about running Home Assistant with Pihole. So this wouldn’t be sufficient right? Home Assistant with Pihole averages around 1.2-1.5GB of RAM.

        • +1 vote

          The Pihole add-on in home assistant is deprecated, so I don't know if there is any way to install it anymore. Adguard Home add-on is available and it serves pretty much the same purpose.

          idk but pihole is wicked with good lists.

          •  

            @HKS: Yeah I experimented with Pihole on a Raspberry Pi which I am dedicating as a network music streamer. I found a repository of very good lists and it has been excellent.

            •  

              @Davesday: what do you use for network music streaming?

              • +4 votes

                @HKS: I am pairing the Raspberry Pi 4 with HiFiBerry Digi2 Pro HAT running on Volumio2. The HAT takes data from the GPIO (I2C) and then sends the digital audio data via Digital Spdif coaxial or Digital Toslink. From there it goes to my Burson Conductor 3XP. This way I can have Tidal, Spotify Connect, Apple AirPlay, streaming local library, etc. My amp does take Bluetooth wireless but it is not lossless. You can technically skip the HAT and do USB direct but the Raspberry Pi probably not optimised with USB jitter, etc. Although it is less of a problem if your amp is very good at jitter rejection and you're running on balanced XLR.

                The benefit of this setup is I don't need to run my computer to feed the amp every time I want to listen to music. This allows me to setup a dedicated music listening station away from my home office. Plus I don't need to run the computer which sucks >100W on idle (its a gaming rig lol)…

          What software were you using? It is a low power platform. Don't expect face-recognition.

          •  

            @manic: I was doing an RSTP stream, of course it can't do facial recognition on the device, it was broadcasting to my Zoneminder instance. It was very flaky, unable to maintain a video stream over any length of time.

            I tried a few implementations including:

            https://github.com/circuitrocks/ESP32-RTSP

            and the instructables post that brought a lot of people to the concept:

            https://www.instructables.com/9-RTSP-Video-Streamer-Using-th...

            And one more that I can't find. One was far better than the others, but I don't remember which one, I don't think it was the instructables version.

        https://randomnerdtutorials.com/install-motioneyeos-on-raspb...

        You basically install a dedicated OS called MotionEYE os onto the pi zero w, hook it up to your wifi, and then throw in a camera.
        If you have a spare webcam already, I would recommend just buying an OTG adaptor (USB> MicroUSB) from ebay for $1 and a power supply (phone charger + long microUSB cable works)
        Oh and having a small microSD card (8gb) will be fine since you upload to the cloud anyway.

        Stick it on the window frame and boom! cloud based video surveillance that you dont need to pay a monthly subscription for (like the $200 solutions out there)
        You could also get more fancy by installing it outside using the shell of a 'fake security cam' you can buy off ebay for $10 or so.

          I would recommend looking at Shinobi cctv. It can be configured to offload the motion detect to the IP camera (assuming you use a hikvision , etc) and runs very light in comparison to MotionOS and Zoneminder.

          I have a Pi 3b setup with 4 streaming cameras the CPU usage is about 4% most of the time.

          •  

            @Dancasper: Interesting, what cameras do you use?

            • +1 vote

              @beebul: A mish-mash of cheap IP cameras I bought over the years (Escam, etc). All of them have a basic motion detect option in the interface. If the cameras can email or ftp when triggered, you can set this up to trigger Shinobi to to record on motion.

              If it provides an RTSP stream, you can use it with the software.

        • +6 votes

          Are you asking if pi-hole restricts access to Internet content based on your geographical location? Or are you asking if pi-hole can help you defeat geo blocks, for instance with Netflix?

          The answer to both questions is no, pi-hole does not do either of those things. Pi-hole blocks adverts (and can block access to particular web sites if you want it to).

          • +2 votes

            @pjetson: I used to use pihole to DNS redirect services such as netflix network wide. I still do it but have migrated to ad guard.

            You just need to feed it a dnsmasq file or hosts format .txt list and redirect to your DNS providers servers.

            @pjetson: I assume he's comparing PiHole to something like PfBlockerNG that has some similar features to PiHole but can also block connections (inbound and outbout) based on the MaxMind GeoID Database.

                •  

                  @Zorlin: You don’t have to fork a thing. The same lists you load into PiHole can be loaded into Adguard Home. Otherwise everything runs locally on your own hardware, not in the cloud.

                  Adguard DNS is hosted by the company and goes via them. Adguard Home is exactly the same thing as PiHole however.

                  If “being a company” is a concern then note that PiHole is developed by PiHole LLC too (a limited liability company of 1 person). Not that I think that matters for open source products.

                  That said, if people like PiHole then that’s fine. Both are absolutely fine products with active development. I personally prefer the PiHole UI but use Adguard Home as the HomeAssistant PiHole addon was depreciated and both products ultimately do what I need, so I was happy enough to swap.

                  •  

                    @Smigit: No issues with companies, even if they need to make money that's okay and that's life. I was misled by the first discussions I found when researching the difference, people were saying stuff about Adguard being able to censor stuff.

                    Next time I'll research for longer before opening my mouth.

                    •  

                      @Zorlin: AdGuard have many products. AdGuard DNS I mentioned is a hosted solution, unlike AdGuard Home. It’s possible some people had concerns about that product instead. Given it’s not self hosted you have to put faith in them.

                      •  

                        @Smigit: Yeah I'm fairly sure that's what it was. I feel like having "Home" in the name of a product makes it harder to land on reliable information… reliably :P when googling it.

      I tried using this as Pi-hole a few years ago and I started getting drop outs. I would just randomly lose internet on my devices. I think the Pi zero was not able to cope up. I ended switching it off, but it worked great when it did.
      This was a few years ago though and Pi-hole may have made performance improvements and it might work now. Also, it may be that I had too many devices connected.
      It’s definitely worth a try though!

      Can confirm about pi-hole.

      I am using a similar setup, but no wireless, just because I wanted the reliability & slightly lower latency of ethernet, plugged straight into my modem/router. These are the components, with links and prices:

      Total = $26.68 delivered for network wide ad-blocking on all devices. Bargain.

      And if you want to make it cheaper still, replace the case with something cheaper.

            •  

              @mouth: I power mine with my shortest micro usb cable plugged straight into the usb port on my modem/router. So my modem/router is the only thing that the pi-hole is connected to, once for Ethernet network, and once for power via usb - which just goes to show that it's effectively providing a network feature that should be in modem/routers, but that they're missing - at some point I'll probably stick the pi-hole to the back of it with removable Velcro stickers. Works fine, it draws very little power. Sorry, should have included this in the list of hardware above.

        I originally tried with one of these ebay micro USB ethernet dongles, it was absolute trash. Barely was able to install pihole as it would drop out or go down to almost 0 transfer rates then spike randomly up to normal speeds.
        Tried working with it for a few weeks before realising it was the issue and not my config or install. I paid the extra and got a highly recommended one from Amazon for about triple the price, but it works perfectly.

            And if we're being serious here it's not a few cents of PLA for large prints is it? You can easily print 500g of filament in one go and if it (profanity) up towards the end you've wasted it.

                @newbiesh: you mean you had kodi & hyperion installed on the Pi0? As I said it might work okay for light videos but you will run into heat & cpu issues for heavy videos. This is primarily due to resource requirement for kodi, hyperion by itself should not be a problem

                  Also all cheap capture devices will only do up to 4k30 and can't pass through the video. The only real option if you are after proper fidelity is to use HDFury gear (but $$$$)
