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.

ios devices (unsure about android) use random MACs on wireless networks by default.

I'm totally with you, except a notification that it's finished would actually be really helpful. It's apparently possible to track a washing machine's progress with a smart switch that monitors power draw; I've got one lying around so might try to implement that soon, to complement my hacky RPi-Ring-doorbell-announcer :)

Wait an hour. It’s done.

Our washing machine offers various programs between 30 minutes and 2 hours and 40 minutes.

Yes, it's not hard to set an alarm, except the timing on the washing machine is unreliable (I've lost count of how many times I've set an alarn with a few minutes extra and still had to wait longer.) It would just be nice to have a little notification - making that chore 1% pleasanter. :)

I'm not opposed to smart homes, I love being able to turn my lights on and off from across the room. But I don't know if I understand the use case for a networked washing machine.

NSA filters the power to sensitive computers.

You can exfiltrate encryption keys if you can monitor power usage.

The traffic stats my UDM shows are complete fiction. The data it presents makes no sense.

Assuming I'd be stupid enough to have a "smart" washing machine, in this case I would've immediately started capturing packets to determine what's going on. Apparently it was a misreporting(!) in the router's firmware, but the opaqueness of modern technology (and the ignorance it tends to perpetuate) can be very infuriating.

Meanwhile my washing machine has zero electronics and is completely predictable and obvious in operation.

They all make a sound when done, you could set up a SoC with a microphone to listen to it. Or monitor power draw. Many ways to do it externally.

A megabyte a day still seems excessive.

If you agree to some form of anonymous tracking for diagnostics I can see 1mb being reasonable. This would be periodic update on things like usage levels, part quality, etc. Most likely that tracking acceptance is buried in some 500 page eula, but thats a separate issue.

Why do you need an entire megabyte for that? Even if you did laundry five times a day, it shouldn't take more than a few bytes to store a few metrics.

Even if you're lazy and uploaded an uncompressed JSON array of objects, that shouldn't be more than a few kB. Way less if you compress it.

A megabyte is a LOT of data.
