When I first started setting up my home automation, I decided on Zigbee, and I very much dove in head-first. I set up dozens of Zigbee devices, and some worked a lot better than others. I have a fairly stable Zigbee network with well over 100 devices, but many of those have been replaced over time. To save others the wasted time and money, I wanted to give a short breakdown of what I've noticed across brands.

• SONOFF: My Zigbee controller is made by SONOFF, and it works well. As far as their motion sensors, not so much (I even made a post about how bad they were about a year ago). Their motion sensors give such unreliable results that they're borderline useless. Their plugs work generally okay, although they do drop off my network occasionally. Overall, they really wouldn't be my first choice.
• Aquara: They make some very slick-looking devices, but they're horrible. Magnetic door sensors frequently just get stuck in an open or closed state, or just drop off the network completely.

I've been using HA for a while; having my home just "do things" for me without asking is fantastic. My lights turn on to exactly the levels I want when I enter a room, my grass and my plants get watered automatically, heating and cooling happens only when it needs to. There are lots of benefits. Plus, it's just a fun hobby.

One thing I didn't expect, though, is all the interesting things you can learn when you have sensors monitoring different aspects of you home or the environment.

• I can always tell when someone is playing games or streaming video (provided they're transcoding the video) from one of my servers. There's a very significant spike in temperature in my server room, not to mention the increased power draw.
• I have mmWave sensors in an out-building that randomly trigger at night, even though there's nobody there. Mice, maybe?
• Outdoor temperatures always go up when it's raining. It's always felt this way, but now it's confirmed.
• My electrical system always drops in vo

To me, it seems like most of Lemmy consists of users who are older millennials (born at some point in the 80s), male, and about 50/50 split between living in North America or the EU.

Do you fit this demographic?

At least in this post, I'm not advocating for any particular political position; I mean for this to be a more generalized discussion.

I have never understood what prompts people to attend political rallies. None of the current US political candidates 100% align with my views, but I am very confident that I made the right choice in who I voted for. That is to say, I'd consider myself a strong supporter of [name here].

To me, it feels like attending a political rally is like attending a college lecture. You have a person giving you information, but you don't gain anything by hearing it in-person as opposed to reading it or watching a recording. If I want to learn something, it's much more comfortable for me to read and article or watch a video in the comfort of my own home. If I want to understand what a political candidate stands for, I'd much rather watch a recording of a town-hall meeting or read something she (oops) wrote rather than taking the time to drive to a rally, get packed

This is more "home networking" than "homelab," but I imagine the people here might be familiar with what in talking about.

I'm trying to understand the logic behind ISPs offering asymmetrical connections. From a usage standpoint, the vast majority of traffic goes to the end-user instead of from the end-user. From a technical standpoint, though, it seems like it would be more difficult and more expensive to offer an asymmetrical connection.

While consumers may be connected via fiber, cable, DSL, etc, I assume that the ISP has a number of fiber links to "the internet." Those links are almost surely some symmetrical standard (maybe 40 or 100Gb). So if they assume that they can support 1000 users at a certain download speed, what is the advantage of limiting the upload? If their incoming trunks can support 1000 users at 100Mb download, shouldn't it also support 1000 users at 100Mb upload since the trunks themselves are symmetrical?

Limiting the upload speed to a different rate than

I generally try to stay informed on current events. With the exception of what gets posted here, I normally get my news from CNN. I tend to lean left politically, but not always.

The problem I always run into is that every news site I read, regardless of where they stand on the political spectrum, is always filled with pointless bullshit. Specifically, sports, celebrity news, and product placement. "Some shitty pop singer is dating some shitty actor" or "These are our recommendations for the best mass-produced garbage-quality fast fashion from Temu" or "Some overpaid dickhead threw a ball faster than some other overpaid dickhead."

What I'd love to find is a news source that's just news that matters. No celebrity gossip, sports, opinion pieces, etc. Just real events that have an impact on some part of the world. Legislation, natural events, economic changes, wars, political changes, that kind of thing.

Does this exist, or is all journalism just entertainment?

A few months ago, I upgraded all my network switches. I have a 16-port SFP+ switch and a 1GB switch (LAGG to the SPF+ with two DACs). These work perfectly, and I'm really happy with the setup so far.

My main switch ties into a remote switch in another building over a 10Gb fiber line, and this switch ties into another switch of the same model (on a different floor) over a Cat6e cable. These switches are absolute garbage: https://www.amazon.com/gp/product/B084MH9P8Q

I should have known better than to buy a cheap off-brand switch, but I had hoped that Zyxel was a decent enough brand that I'd be okay. Well, you get what you pay for, and that's $360 down the toilett. I constantly have dropped connections, generally resulting in any attached devices completely losing network connectivity, or if I'm lucky, dropping down to dial-up speeds (I'm not exaggerating). The only way to fix it is to pull the power cable to the switch. Even under virtually no load, the switch gets so hot that it's pai

I have been using the BlueIris NVR integration (from HACS) for quite some time, and it works great for triggering BI from HA. I've trying to do the opposite now: Fire off automations in HA whenever BI detects motion on one of my cameras.

I've never used MQTT before, so I'm learning as I go, but I think I have most of my setup configured properly. I've installed Mosquitto and the MQTT integration in HA. I've configured BI to connect to HA, and running "Test" in the "Edit MQTT Server" menu in BI shows a good connection and no errors. I've set my cameras to post an MQTT event when the alert is triggered (and I've verified that the alerts are in fact being triggered).

Nothing happens in HA, though. The "Motion" sensor for my camera in HA stays at "Clear." In fact, the history shows no change at all, ever.

I have the events in BI set up as follows: On Alert: MQTT Topic - BlueIris/&CAM/Status and Payload - { "type": "&TYPE", "trigger": "ON" } On Reset: Exactly the same, but change *ON

This isn't strictly "homelab" related, but I'm not sure if there's a better community to post it.

I'm curious what kind of real-world speeds everyone is getting over their wireless network. I was testing tonight, and I'm getting a max of 250Mbit down/up on my laptop. I have 4 Unifi APs, each set to 802.11ac/80Mhz, and my laptop supports 2x2 MIMO. Testing on my phone (Galaxy S23) gives basically the exact same result.

The radio spectrum around me is ideal for WiFi; on 5Ghz, there is no AP in close enough range for me to detect. With an 80Mhz channel width, I can space all 4 of my APs so that there's no interference (using a non-DFS channel for testing, btw).

Am I wasting my time trying to chase higher speeds with my current setup? What kind of speeds are you getting on your WiFi network?

I have been programming in C++ for a very long time, and like a lot of us, I have an established workflow that hasn't really changed much over time. With the exception of bare-metal programming for embedded systems, though, I have been developing for Windows that entire time. With the recent "enshittification" of Windows 11, I'm starting to realize that it's going to be time to make the switch to Linux in the very near future. I've become very accustomed to (spoiled by?) Visual Studio, though, and I'm wondering about the Linux equivalent of features I probably take for granted.

• Debugging: In VS, I can set breakpoints, step through my code line-by-line, pause and inspect the contents of variable on-the-fly, switch between threads, etc. My understanding of Linux programming is that it's mostly done in a code editor, then compiled on the command line. How exactly do you debug code when your build process is separate from your code editor? Having to compile my code, run it until I find

I've noticed recently that my network speed isn't what I would expect from a 10Gb network. For reference, I have a Proxmox server and a TrueNAS server, both connected to my primary switch with DAC. I've tested the speed by transferring files from the NAS with SMB and by using OpenSpeedTest running on a VM in Proxmox.

So far, this is what my testing has shown:

• Using a Windows PC connected directly to my primary switch with CAT6: OpenSpeedTest shows around 2.5-3Gb to Proxmox, which is much slower than I'd expect. Transferring a file from my NAS hits a max of around 700-800MB (bytes, not bits), which is about what I'd expect given hard drive speed and overhead.
• Using a Windows VM on Proxmox: OpenSpeedTest shows around 1.5-2Gb, which is much slower than I would expect. I'm using VirtIO network drivers, so I should realistically only be limited by CPU; it's all running internally in Proxmox. Transferring a file from my NAS hits a max of around 200-300MB, which is still unacceptably sl

In c++17, std::any was added to t he standard library. Boost had their own version of "any" for quite some time before that.

I've been trying to think of a case where std::any is the best solution, and I honestly can't think of one. std::any can hold a variable of any type at runtime, which seems incredibly useful until you consider that at some point, you will need to actually use the data in std::any. This is accomplished by calling std::any_cast with a template argument that corresponds to the correct type held in the std::any object.

That means that although std::any can hold a type of any object, the list of valid objects must be known at the point that the variable is any_cast out of the std::any object. While the list of types that can be assigned to the object is unlimited, the list of types that can be extracted from the object is still finite.

That being said, why not just use a std::variant that can hold all the possible types that could be any_cast out of the object? S

I'm looking for a portable air conditioner (the kind with 1 or 2 hoses that go to outside air). The problem I'm running into is that every single one I find has some kind of "smart" controller built in. The ones with no WiFi connectivity still have buttons to start/stop the AC, meaning that a simple Zigbee outlet switch won't work. I could switch the AC off, but it would require a button-press to switch it back on. The ones with WiFi connectivity all require "cloud" access; my IoT devices all connect to a VLAN with no internet access, and I plan to keep it that way.

I suppose I could hack a relay in place of the "start" button, but I'd really rather just have something I can plug in and use.

I can't use a window AC; the room has no windows. I'll need to route intake/exhaust through the wall. So far, I can't find any "portable" AC that will work for me.

What I'm looking for is a portable AC that either:

• Connects to WiFi and integrates with HA locally.
• Has no connectivity but us

Yesterday, Brian Dorsey was executed for a crime he committed in 2006. By all accounts, during his time in prison, he became remorseful for his actions and was a "model prisoner," to the point that multiple corrections officers backed his petition for clemency.

https://www.cnn.com/2024/04/09/us/brian-dorsey-missouri-execution-tuesday/index.html

In general, the media is painting him as the victim of a justice system that fails to recognize rehabilitation. I find this idea disgusting. Brian Dorsey, in a drug-induced stupor, murdered the people who gave him shelter. He brutally ended the life of a woman and her husband, and (allegedly) sexually assaulted her corpse. There is an argument that he had ineffective legal representation, but that doesn't negate the fact that he is guilty.

While I do believe that he could have been released or had his sentence converted to life in prison, and he could have potentially been a model citizen, this would have been a perversion of justice. Actions

I just set up a local instance of Invidious. I created an account, exported my YouTube subscriptions, and imported them into Invidious. The first time I tried, it imported 5 subscriptions out of 50 or so. The second time I tried, it imported 9.

Thinking there might be a problem with the import function, I decided to manually add each subscription. Every time I click "Subscribe," the button will switch to "Unsubscribe," then immediately switch back to "Subscribe." If I look at my subscriptions, it was never added.

My first thought was a problem with the PostgreSQL database, but that wouldn't explain why some subscriptions work when I import them.

I tried rebooting the container, and it made no difference. I'm running Invidious in a Ubuntu 22.04 LXC container in Proxmox. I installed it manually (not with Docker). It has 100GB of HDD space, 4 CPU cores, and 8GB of memory.

What the hell is going on?

As is stands, parents are able to claim their children as dependents on their tax returns, which lowers their overall tax liability and in effect means that the parents either pay less in taxes or receive a higher return at the end of each year.

Until they reach the age at which they can work, children are a drain on society. They receive public schooling and receive the same benefit from public services that adults do, yet they contribute nothing in return. At the point that they reach maturity and are gainfully employed and paying taxes, they become a functioning member of society.

If a parent decides to have a child, they are making a conscious decision to produce another human being. They could choose to get a sterilization surgery, use birth control, or abort the pregnancy (assuming they don't live in a backwards state that's banned it). Yet even if they decide to have 15 children, the rest of society has to foot the bill for their poor decisions until the child reaches adulthoo

The majority of my homelab consists of two servers: A Proxmox hypervisor and a TrueNAS file server. The bulk of my LAN traffic is between these two servers. At the moment, both servers are on my "main" VLAN. I have separate VLANs for guests and IoT devices, but everything else lives on VLAN2.

I have been considering the idea of creating another VLAN for storage, but I'm debating if there is any benefit to this. My NAS still needs to be accessible to non-VLAN-aware devices (my desktop PC, for instance), so from a security standpoint, there's not much benefit; it wouldn't be isolated. Both servers have a 10Gb DAC back to the switch, so bandwidth isn't really a factor; even if it was, my switch is still only going to switch packets between the two servers; it's not like it's flooding the rest of my network.

Having a VLAN for storage seems like it's the "best practice," but since both servers still need to be accessible outside the VLAN, the only benefit I can see is limiting broadcast t

I've been running HA for a while, and it's been working well; I haven't had to change much in a few months. That being said, it's fun to tinker with it, and I'm curious to hear what kind of automations the rest of the community is using. What automations are you most proud of? What are your favorite? What kind of interesting automations have you written?

My personal favorite is an automation that displays the current "apparent" temperature on a Hue bulb. It takes an average of the temperature, humidity, and luminance around my property and uses the average to compute an "apparent" (feels like) temperature. Then it applies a cosine function to the apparent temperature (to approximate how people feel temperature change), uses the resulting value to calculate a level between blue and red in CIELAB (a perceptually uniform color space), converts the results to RGB, and sets the color value of the hue bulb. The result is a bulb that changes color so that the change in color (as perceived by

I have a decent amount of video footage that I'd like to share with friends and family. My first thought was Youtube, but this is all home videos that I really don't want to share publicly.

A large portion of my video footage is 4k/60, so I'm ideally looking for a solution where I can send somebody a link, and it gives a "similar to Youtube" experience when they click on the link. And by "similar to Youtube," I mean that the player automatically adjusts the video bitrate and resolution based on their internet speed. Trying to explain to extended family how to lower the bitrate if the video starts buffering isn't really an option. It needs to "just work" as soon as the link is clicked; some of the individuals I'd like to share video with are very much not technically inclined.

I'd like to host it on my homelab, but my internet connection only has a 4Mbit upload, which is orders of magnitude lower than my video bitrate, so I'm assuming I would need to either use a 3rd-party video hos

I've been going through my system logs and working on resolving the miscellaneous errors; mostly it's just due to poorly-written automations where the automation would be called while it was still running. Easy fix.

What I can't seem to fix is a constant stream of "Unknown cluster command" errors on cluster 0xef00 coming from ZHA. I've discovered that the 0xef00 cluster is a manufacturer-specific cluster. All of my errors come from Tuya mmWave sensors; apparently Tuya uses this cluster for inter-device communication.

All of my devices work, but this error is polluting the logs to a large degree; right now it's showing over 100k instances of this error. Is there a way to have HA just ignore this cluster completely? It's not causing any issues with functionality, but I would rather the logs just show actual errors so I can more easily identify problems and fix them.

I've read that Z2MQTT doesn't have this issue, but swapping from ZHA to Z2MQTT is not an option for me, especially for
