Yes, though it might be a bit underpowered. I'd look also at their RouterBoard line. I haven't used DSL in a long time, but it should he possible.

Man, sorry I don't know why Lemmy doesn't show me reply notifications consistently.

Nah, unfortunately I watched this video a couple weeks ago and while it is a waste of time, there is at least a bit more to it than that. DNS is part of it but it's more "I built a regular router". The backstory is the OP's apartment has some kind of shady wireless ISP as their only option. They build a router to hide connecting multiple devices behind NAT (which they barely even talk about), but they don't do much else to actually hide devices. Honestly it's really basic and could be achieved with a cheap travel router, though the 3D printed enclosure they built is pretty cool.

Even if you're not a Linux networking neckbeard and want to learn this video isn't worth watching because it just glosses over the actual useful/interesting/complicated parts.

Oops didn't see your reply. Yes, it would, though RouterOS is a bit difficult to use. I have some Mirkotik gear and it's a pretty great hardware if you're willing to learn the software. General configuration is the same -- buy one of their routers (not the stuff like the switches that can kinda do routing, you want one of the actual routers) with enough ports, put a dedicated network with DHCP on each port, WAN on another, firewall rules to keep the networks separate.

Beware that Mikrotik hardware has some subtleties with what capabilities each box has because they rely heavily on having hardware acceleration, so you wanna read the specs and documentation carefully to make sure the one you pick that meets your needs. PfSense/OPNSense don't really have that caveat because they do all the routing on the main CPU and just use a more powerful CPU than Mikrotik usually does (though still lower power generally... a lowly N150 CPU can route like 2-3 GBPS of traffic easily).

FWIW PfSense and OPNSense are both open source software from reputable companies built on FreeBSD. For the random cheapo boxes from Amazon/Aliexpress you absolutely want to wipe them and install a fresh copy. You can also buy official hardware from the company, but it's more expensive. Protectli is also a reputable brand of mini PC that is sold specifically with PfSense/OPNSense in mind that isn't crazy expensive.

Edit: just so you know, any "real" (as in, not the home router all in one junk you can buy at the electronics store) router can do what you're asking as long as it has enough ports, be it Cisco or Ubiquiti or any other. This is a very common use case, and a core feature of a router.

Cheap N150 box off Amazon or Aliexpress with four network interfaces, install PfSense or OPNSense, make a separate network for each of the 3 drops and use the last port for WAN.

Previous 3 major release upgrades I've done were smooth, ymmv

If your purpose is long term archival you should probably be using M-Disc Blu-rays anyway, which are still actively made by Verbatim (and one other company).

Not entirely sure about the de-google'd version of the Home Assistant companion app, but I know the regular companion app uses Firebase (and whatever the Apple equivalent is called, I forget) to deliver notifications, and it still would using Telegram as Telegram also uses Firebase. Apprise is a bit different as it can use multiple backends. Regardless, there are multiple ways to do things. Ntfy iphone and google app do not route your data through a third party server. I self host the ntfy server on my own machine and domain and my phone connects to it and receives data. It will deliver notifications wherever I am, not just in my LAN. It also provides a nice UI akin to Pushbullet I can use to send myself stuff privately.

You can't replicate all of what ntfy does with Home Assistant. There's more to it than just delivering notifications, it's the whole app frontend and persistent data etc. If it's not clear to you what it's for from my description you might have to go look into it yourself. Look at PushBullet, that's most similar to what I primarily use it for.

Home Assistant notifications and almost all other notification services on phones actually route notifications through a cloud service like Firebase because Apple and Google try to railroad apps into their platforms. Ntfy lets you actually self host notifications without a third party, but also without killing your battery.

That's not the main thing I care about, though. Mainly I use it as a self hosted replacement for PushBullet, to share links and files with myself across machines and do some light alerting for servers and stuff (e.g. TrueNAS errors). Some of that could he done with HA, but ntfy is just better for some other uses with stuff like its web ui.

Plus, apart from that ntfy is really easy to integrate with other stuff, like its easy to send a notification from a shell script or web hook so you can hack it into things that don't otherwise support notifications (there are also lots of things that support ntfy natively, e.g. the arrs).

Actually Budget for finances, Nextcloud for everything office and organization, Home Assistant for home automation, paperless--ngx for storing and sorting documents, freshrss for news, ntfy.sh for notifications.

Artificial elemental transmutation of lead into other elements is not just fantasy, it's entirely possible and happens in particle accelerators and nuclear reactors. It's just extremely impractical as it's an extremely slow process at anywhere near the particle fluxes we can practically achieve. Plutonium is made through a similar process (though the exact mechanism used to produce plutonium is relatively more efficient) as well as small quantities of useful radioisotopes, but it is also possible with lead.

Only a sample size of one here, but I've used it for quite a while now and it's definitely one of the more stable and reliable apps I self host. It's a delight.

This is a super cool bit of reverse engineering. Another interesting way to go about it would just be to examine the pinout and reflash with ESPhome. I'm betting the ESP32 ultimately only twiddles some GPIOs with maybe a bit of PWM, that was how the air purifier I re-brained with an ESP8266 way back worked.

Is the brand of air purifier mentioned anywhere? I would be interested in getting ahold of one that is already run on an ESP32.
