Did you keep a straight face while you suggested that people actually upgrade firmware?

It's easy to build it in a way so that the worst that the software can do is cause it to turn into a "dumb" fridge.
My problem with this whole hatred of iot is that it's not productive.
it's a bunch of people commenting how the trend is dumb and how everything was so much better in the past. Nobody ever gives suggestions on how to improve it, or how to fix some of these issues, or even what they would like to see. It's always just "Who wants a wifi light switch anyway?" or "Oh great now my door lock can freeze".
If it's so easy, why don't more companies do it? Why didn't Nest build their thermostats so that when the battery runs out, it reverts to a "dumb" thermostat instead of turning off your heat? http://www.theguardian.com/technology/2016/jan/15/bug-nest-t...
Very few actually pull operating current from the 24v C wire if it even exists on the given system. If it doesn't, R (the switched 24v power for Heat and Cold signals) isn't guaranteed to continually have current. Only when your Heat is turned on (probably a standard toggle lightswitch on the side of your furnace) will there be current on the Rh line, and only when your AC is enabled (possibly a breaker shunt on the side of your house near the condenser unit in a small box) will there be current on the Rc line.
Nest tries to recharge it's battery by trickling the C wire, if available, and if not it will try to charge off of one of the R wires, either during normal operation, or it will try and "pulse" the heat signal to pull a little bit of current to keep going. Thermostats were designed at a time where they didn't even consume any electricity on their own. We're trying to retrofit computers into signaling system, not a circuit.
The GP is right: most new thermostats don't take power from the 24VAC line. That surprised me when my heat wouldn't come on one morning because the battery was too weak to pull in the relay for more than a few seconds. That's what I get for ignoring the "low battery" warning! All my previous electronic thermostats only used the battery as a backup.
In any case, are you really saying that using a toxic metal (mercury), or an imprecise bimetallic strip is really an improvement over a simple $10 electronic thermostat?
A dumb digital thermostat is just a thermocouple and a relay, which you could rig together with very little EE knowledge and a weekend with an Arduino.
It's clearly more work to do it that way, as you'd need multiple "layers" of firmware/code which all need to communicate and run on their own, but i personally see that as insurance against the exact situation you are describing.
Nest is far from what i'd consider a good IOT company. They are the epitome of vendor lock in, proprietary and buggy code, and shitty support.
The thing I don't get with 'control everything with your smartphone!' is that people don't think about everyday use. It's like the people that design these products don't look at the actual, repeated use cases. Why would I want to pull my phone out of my pocket, unlock it, find the app I need, launch the app, wait for it to connect, hit the buttons I want....
(Even when I'm on Android and I can have an IoT control widget on my homescreen, that's still pulling the phone out, switching it on, unlocking it with my fingerprint, finding the page, hitting the button.... oops I forgot to turn Wi-Fi back on, better do that....)
I think IoT is great, but to do a great job at it you need to design the product with that in mind to begin with. The whole architecture of the product has to fit (see again, Hue). Sure, picking an Android tablet is easy, but why would you architect all that complexity? Why not a touchscreen device with a really simple real-time OS that does only what it needs to do?
I'm confident that this will all be self-correcting in the end. Consumers and 'the market' are smarter than we give them credit for. Certainly it takes a long time for them to react, but I think that when enough of the public is jaded by 'bad IoT' and the fad phase has passed, the actually good IoT products will survive and those companies that really think about their designs as a whole will be rewarded.
This is exactly the sentiment i was talking about though.
If you buy a car that had a faulty AC unit, do you just swear off cars altogether because "they all have shitty AC"?
Why do so many people like to bring up bugs/issues with poor iot devices and act like it is something that can't be improved or fixed?
But it hasn't been that long at all, and there are people doing it right.
The problem is that they are expensive and don't offer the same amount of features that some people want.
Take the "traditional" smarthome networks like z wave and friends.
I have a z wave light switch that works as a lightswitch 100% of the time. I actually installed the switches before i had a controller for them.
Add a controller and you have a "smarthome".
Connect that controller to your wifi and you have the ability to control these things safely from within your own network using anything from a bash script to shitty iphone apps.
Connect that network to the internet through a firewall and an authentication system and you now can control all of that stuff securely across the planet.
If any one of those breaks, functionality is reduced. Internet is down, i can't control it outside the house. Controller goes down, i can't control them as groups or from within the house but still "remotely". But it will literally always turn on/off the lights when i hit the switch. I don't need to worry about the security of a cheap chinese zwave knockoff thing because the controller is that gatekeeper.
That's IOT done right.
But people don't want to pay the money for that, they don't want to pay an electrician to come out and install them across the whole house, they don't care about security or what happens when the internet is down, they want a light they can control from their phone for as cheap as possible as fast as possible. And of course when people are asking for a product, manufacturers are going to make it.

Hence my shoutout to IoS! :)
Which might be quite a challenge with some devices when your neighbors drown you in free WiFi.

Fifteen years ago. Wow, I love the way I gave Jini a shout-out.
Nothing in remote/automatic updates requires being brickable. Don't buy such a crappy fridge.
Or, call a serviceman to fixe it, just like you would today with dumb fridge.
How does Tesla implement updates?
An opt-in switch is merely convenience for the incredibly thin % that bothers with this kind of thing. And that % will actually be informed enough to not opt in.
Come to think of it, that % will likely be informed enough not to buy this kind of device in the first place.
Tesla has a pretty vested interest in shit keeping working considering it's a pretty luxurious and high-profile product. The cut-price manufacturer of your $20 lightbulb or $300 fridge? Not so much.
It's not a matter of luxury, it's a matter of having people work on it who care.

Source: Chromebooks are awesome, and even with excesses like this, they're still the cheapest to operate by far.
A comment in https://bugs.chromium.org/p/chromium/issues/detail?id=323010 claims that the BSSID is used for a "suspected" state, but that may not be enough to actually stop it from downloading updates, but I'm far from an expert in that domain.
In short, identifying tethering states with iOS seems to be hard.
