Why wouldn't you allow it in isolation?
How isolated are we talking? A device that only has access to the internet can still get botnetted and send malicious traffic from your IP. Or burn your data cap, or spy on you for the vendor.
But the comment said "I wouldn't allow it on my local network", not "I wouldn't allow it on the Internet".

#13Respect, but this is kinda the hard way - I just plugged mine (dumb machine, not smart) in via an energy metering plug, and when energy use drops to less than 10W for more than 2 minutes, it’s done - very simple homeassistant automation. Convenient for me as the machine is 500m from the house.
Yeah this is my approach too. Though I need to revisit the thresholding.

I do the same,works great. I liked it so much that im doing the same with my microwave, after removing the annoying beeper it had. Now i get a decent single short beep and can monitor how often I've used it.

Now I want to know why your washing machine is half a kilometer from your house.
Seriously, me too. I also want to know how they transport the laundry to/from the machine. I'm hoping for a conveyor belt of sorts.

For untrusted IoT devices I’ve found that sticking them on the IoT VLAN (so no device-to-device communication, and either no or extremely limited internet access; but I let my trusted clients punch through to IoT devices) has allowed me to retain all functionality whilst being confident they’re not up to anything I don’t want or expect.

Couldn't you just set a timer for 45 minutes, or whatever? Is there that much variance in load times?

Nex is a cybersecurity student in a house of similar people, they're gonna take every way :3

> The plan is, in future, since we can't hack something that doesn't have a brain, to instead attach a brain to it. The dishwasher is easy, we can just whack that on a smart plug and monitor when the power use surges and drops. The dryer is a bit more difficult, since they pull a LOT of power, and smart plugs typically either don't support that much power, or are incredibly expensive. So that's likely going to be some fancy vibration sensor-based thingy
Re: I hacked my washing machine
#19I'm surprised you let your washing machine into your network. I now get the appeal of just an alert the washing machine is done. But I could not for the life of me allow any of these kinds of devices onto my home network. Even in isolation...
Hey, blog author here. It only had access to the internet for a brief second, and even then it was on an entirely separate network because of how I just set up my openwrt router as a client to the main network. Our guest network is completely isolated, an explicit firewall rule had to be added so that my script could communicate with the washer while it's on this network. It has no access to anything but itself, and occasionally hears the screams of my script demanding it serves up data.
It has access to nothing, only my script has access to it - I don't see a risk here. I still have the heebie jeebies knowing it's connected to anything at all, or even the fact that it can do that, but also spending a night hacking a washing machine was incredibly funny to me and totally worth it. Plus, got some useful notifications out of it.

#20I suggest pushing washing machine metrics to Prometheus, it just asks for it.
