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.

I get significantly cheaper electricity at night ($0.12 vs > $0.50/kwh, stupid California). Being able to schedule saves money, not that WiFi is necessarily required.

When I was in college, the machines in my dorm building’s laundry room would send you an SMS when the cycle finished. It was super handy, and would be awesome to have if your home is multi-level (or the machine is tucked away where no one can hear it scream)

Earlier quoted context omitted.

It shouldn't even need internet access. IoT is a stupid name. It's just networking.

Uhhh, alright. Anyhow, many devices require network access for useful functionality. That network is ideally zigbee. (It's also possible for Bluetooth to make up for some of the lost featureset for non-realtime applications, so I'd favor Bluetooth smart devices over wifi smart devices.)

Yes, Zigbee is the way to go. But the point is there shouldn't be any internet involved. Using the internet protocol on wifi is the stupidest way to do this kind of stuff and leads to dumb crap like your washing machine phoning home.

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 :)

A megabyte a day still seems excessive.

Other users having low data usage doesn't prove they also have low usage?

Are people so uncomfortable saying "we don't know" that they use such loose reasoning to "get the answer"?

I'll re-read the article/tweets, maybe I missed something.

A couple of notes: 1. If you must have an IoT device, favor zigbee. 2. Put your IoT devices on a segmented network that you've throttled. IoT devices neither need nor deserve privileged network access. 3. Probably don't use a consumer grade router if you know how to monitor network traffic. 4. That all being said, it feels unlikely that an IoT device would be exposed on a properly configured router to anything beyond…

I disagree with some of these points:

1. Z-wave is better, but Wifi can be fine in the right environment. Like, my weather station uses Wifi because it sends a few bytes of data to a server once a minute. No need for an additional protocol going on that interferes with everything else on 2.4GHz anyway. I also use Wifi for a sensor I put in my box that stores 3D printer filament to measure its humidity, so I know when to recharge the desiccant. An ESP32 wakes up every half hour, measures the humidity, and sends it over HTTPS to an InfluxDB instance in "the cloud". Its tiny lithium polymer battery lasts a year. It took me maybe an hour to design the hardware and write the software for it. Why do anything more complicated? Why bother with an esoteric protocol when you just want to use the Internet?

3. Consumer grade routers are great these days. I have a 10G WAN, 10G LAN, and Wifi6e on the router that Verizon provides with my service for free. To buy something like that myself, I'd be spending 700 or 800 dollars so that I can pretend to be a sysadmin on my day off. Why bother?
