#72Even if this device (presumably with known vulnerabilities) isn't directly reachable via the Internet, could the device be bumped off the WiFi and onto an impersonating AP, where the device can be taken over?
The photo on the retail box has a tablet camera hole. Does this particular unit have a camera and mic, placed in a living area?

#73> There were two strings printed with labels “SSID” and “Pwd”. I froze in horror. They wouldn’t dare. It is literally 3 meter distance. These are embedded devices, they do not need this complexity… Not surprising at all. I would expect that a lot of these are bought as retrofits, and not as a part of new construction. Running wires through existing walls can be annoying, and they don't want to put that barrier to sal…
> Probably don't need to be so worried here. If it's a 3A fuse, the entirety of your apartment's mains power is not running through it.
If it's a "3A fuse" that doesn't blow at 6A or worse, then it will get very hot (fire hazard) if/when there's a short regardless of the distance to the mains power.
If it truly is a 3A fuse, then great. If it's bought from Amazon then I doubt it's truly a 3A fuse.

#74I really hope we'll look back at this fad of android powered wifi domestic IoT devices one day and laugh about how silly it all was. Not an IoT hater. I've worked for IoT companies, and there's a lot of very smart embedded engineers doing very cool things in the space. But an old android tablet installed in the wall with a WiFI point? oh dear.
What do you recommend as an alternative?
basic electronics, mostly

#75Did you take notes along the way? Usually when I am "exploring" a problem like that it's hard to reproduce my steps later.
For me, a particular browser window's (many) open tabs are usually a pretty good record.

#76“DATE & TIME ARE ALWAYS CORRECT AND NEVER NEED TO BE ADJUSTED” sounds like it’s straight out of a fever dream

#77Earlier quoted context omitted.
The person lives in an apartment in Britain. Apartments are only built in towns and cities, and are generally within walking distance of convenience shops and supermarkets. Every plug in Britain has a fuse, so they are about as easy to buy as replacement light bulbs. Probably on the same shelf.
This is fascinating! I did not know this about british plugs. Why is that? Is it a safety measure?
British household electrical systems are normally built as one large ring circuit, originally in order to save copper after WW2.
This means you don't have breakers for each branch circuit (there are no branch circuits), just the single mains breaker for the house. This single breaker is too large to trip from a short from occuring in the smaller wires inside an appliance.
So each plug (or hardwired device) needs it's own dedicated smaller fuse instead.

#78"urban archeology": The device was using an ARM processor extension that could directly execute Java bytecode. https://en.wikipedia.org/wiki/Jazelle
I want to know more. History of java is just insanely weird.
SIM cards and secure elements (contactless credit cards) both use this, or did at one point.

#79Yet another reminder: I really need to get off my ass and isolate all of the IoT junk connected to my network away from home/work/lab devices.

#80WiFi is not only reasonable but preferable. Because if a cat5 cable is going to be ran, it'll be done by an electrician. And when they get to the end of a spool, they will break out the wire nuts and splice away. I've seen it first hand.
Not even electricians can screw up WiFi :D
