PSA: If you buy any hardware that requires an internet connection to work return it as faulty. Is this washer going to get software updates for it's entirely lifespan? "It's behind NAT and a firewall". Well if one of your other devices get infected and it gets infected now what? "But NAT" you heard of STUN servers? It doesn't need to be in a botnet to be malicious... That's assuming your ISP router from 10 years ago…

What if I'm using a Unifi UDM router and all of my IoT devices are on a separate VLAN and the firewall prevents them from initializing connections to any other devices on the local network?

> In a follow-up post a day after his initial Tweet, Johnie noted “inaccuracy in the ASUS router tool.” Other LG smart washing machine users showed device data use from their apps. It turns out that these appliances more typically use less than 1MB per day.

My Ubiquiti UniFi UDM is not good at device identification. It's kind of annoying because I have this big list of devices on the network and it's peppered with devices that I know don't exist. I'd appreciate it if it said something like "Maybe iPad Air", instead of just "iPad Pro 2nd Gen" when I know no such device is on my network.

Cisco ISE thinks all iPhones are FreeBSD.

When I worked in a storage group years ago, the system that controls swipe card access for a building generated something like 3TB of Java exceptions a month. Because of the criticality, it was on high tier reliable SAN storage, replicated to a second site. IIRC, storage was like $80 Gb/mo.

Love how you said exceptions, rather than just logs. I am unfortunately (painfully) aware of exactly what you mean. The storage costs were the cherry on the top. But seriously, $240k and nobody raised a stink?

It’s one of those things that cloud storage helps with.

Because it was on prem, the chargeback model was associated with the business unit and not super granular. It got lumped in with another business function because it should be a trivial workload.

I found it when I was doing estimates for a new platform and the app’s growth numbers didn’t add up! Even at $240k, it wasn’t an obvious outlier.

LG washing machines are the bane of my existence today because we have a power outage that will last for quite a while, clothes inside the washer, in water, and a locked lid. So far I haven't any way to open the damn thing without taking a hammer to it.

Having a little UPS handy might be useful if you have power outages. You could just plug the machine into it to unlock it. Ridiculous, but an idea.

Definitely trying this. Brought our UPS to the hotel to charge it up.

a program running on a 480 megahertz microcontroller can quite reasonably crash a million times a second; even a single 80-character error log line would be 80 megabytes per second or 7 terabytes per day. and it would be reasonable to record more telemetry from a crash than a single line

How far we have come. Back in my day, a program could only crash a few thousand times a second.

To err is human. To really screw things up we had to invent microcontrollers.

My worry would be that you'd have to do some diagnostics on the audio to determine the actual sound. The loudest noise my washer makes is the spin/rinse cycle, which is right before the sound it makes when it's done. You can't just key off of "loud noise" and I don't know how hard setting up to listen to specific frequencies for alerting is.

> You can't just key off of "loud noise" and I don't know how hard setting up to listen to specific frequencies for alerting is. Fast fourier transform on the audio would give you volume for each frequency range. That probably requires some DIY hardware & programming. But a power metering plug would be a cheap off-the-shelf solution. Find the ones pre-flashed with ESPhome for ~$15-20, find thresholds for ON/OFF with…

Yea, I'm for sure that it's possible, but it's harder than just getting a sensor for noises larger than some Db.

Occasionally it's fun to discover new devices. "It thinks my WiFi dog feeder is a Technoelectrocom 56XR-2000? What the hell is (was) that?"

I found out that unifi plug in doorbell chimes use an esp32 this way because I saw one on my devices table, before it had booted fully and handshook as it's real Identity

Do you mean the non-PoE version? I have the PoE version sitting in a box somewhere and I'm a ESP32 enthusiast so I'm wondering if that's what I'll be doing today. Surely they're using it just as a WiFi coprocessor? Or...?

The non PoE one, the one that just plugs into a normal power outlet

My PoE one has only ever identified as what Ubiquiti thinks it is, so no idea

> "But I keep an eye on my stuff" what about the 5billion other users in the world?

And I concider thr UDM to be IOT in and of itself but that is arguably an opinion not objectively true

I guess it might be quite fun to graph that and overlay the graph of the current cycle over an original benchmark - it might indicate when, for example, the heating element was no longer working as efficiently.

I imagine that would get complicated pretty quickly. Water takes significantly longer to heat up in the winter just because it's so much colder to begin with.

Similarly basically all washing machines today weight laundry and stuff then tune cycle duration, amount of water, drying time (if applicable), etc...
