  • What you might deal with is heat soak if the fans can’t move enough air over the condenser core. But modern vehicles are immensely more efficient than even 10 year old vehicles.

    You’re point?

    They’re not designed to idle for extended periods, and doing so puts strain on the systems. that the cars are “more efficient” doesn’t change that.

    the AC compressor isn’t a significant load, no. But it’ expects a certain engine RPM coming into it, and it’s designed at that. It’s significantly less when the engine is idling because that’s below it’s designed range. There’s a reason the manufacturers tell you not to idle your car for extended periods (mine says more than 10 minutes, my last one said 5.) and this is part of it.

    the increase in RPM modern cars do isn’t for the AC system. it’s to keep the engine from stalling and running smoothly… the compressor is still not designed to operate at that RPM.


  • However, disagree with the statement that a climate control system is not meant to be operated while idle. That is an old myth that I expect came from back when there was fewer electrical components in the car so not turning the ac /off/ before turning the vehicle off would risk damaging the cars electrical.

    that’s not actually a myth. The car is functionally not designed to be left on idle for extended periods. (Note, I’m saying extended periods. Warming/cooling your car at idle is normal. idling at a stop light is normal. Five minutes while waiting to pick some one up is normal. Leaving it to stay cool for 2 hours is outside that design window.)

    When an engine is idling, it’s turning at a lower RPM than when moving. of particular note here is that the alternator and AC compressor are both driven by the serpetine belt directly connected to the crankshaft. The lower RPM makes both less efficient. For the compressor, what this means is that the AC system is turning more slowly than it normally would, reducing the total amount of cooling. For the alternator; it produces less electricity and may cause the battery to be discharging. Depends on some things, including how hard the AC is having to work, etc.

    Further, because the car is not moving, there is less air moving around the engine compartment (or wherever the radiator for the engine and the AC is located.) This equates to higher operating temperatures for the engine, as well as yet more reduced ability for the AC system to remove excess heat from the cabin.

    just because an AC can be run at idle for extended periods doesn’t mean it’s designed to, and doing so, especially on old or poorly maintained systems, in excessive heat, is likely to cause it to crap out where it wouldn’t have normally. Is it a particularly high probability? Not really. Is it still too high considering it’s a life-safety system? fucking absolutely.

    Because apple only maintains phones on an individual level?

    And probably literally everyone who writes apps for iOS, as they would now need to account for everyone’s potential behavior.

    It’s not “only”. Especially if you had to account for every possible variation in hardware. It’s more complexity and that means more opportunity for bugs.

    <chuckles on linux> “he doesn’t know how to use the middle mouse button!”

    (for people who may be unaware… in most linux distributions- all of them that I’ve used, and I’ve used a fair number; clicking middle mouse with text selected cuts and pastes the text. it’s one of those features that, once you get used to… you just can’t let go.)



  • My dishwasher is completely fine without the cloud. Period. Full stop.

    OP reports loss of functionality. Functions, that are, quite frankly standard features on all not-IoT machines. Functionality which, frankly, you paid for, and which in no way actually require homecontrol to use.

    There is no need to put it on the network, but if you want to, and are paranoid, you can connect it to an isolated network. If you dont want to, dont, and the dishwasher will work.

    only if you find it acceptable to not have full functionality. “you can put it on an isolated network”… is very much like “let them eat cake.”

    Particularly if you consider the trend to force this in all sorts of things- ranging from toasters, refridgerators, ovens, stovetops, coffee makers, etc. Inorder to adequately protect mimizie the risks associated with these devices, you’d have to have a dedicated network for each one.

    and yes, the reason they’re forcing you to use the home control app to get these features is to intrude into your privacy.

    Notifications aside, none of the functions it enables require internet access, or even network access. There’s exactly zero reason to put it on the network. And as for notifications, I don’t know anyone that’s going to rush home or stop what they’re doing to put dishes away the moment the machine is finished cleaning them. is it possible you’re an exception to that? sure. I guess. but the vast majority of people- in my experience- won’t be finding anything that actually requires internet for to be all that useful.

    Which- in case there was any confusion- is why they shut off functions people use all the time. To force people to use their app. Which, if they weren’t some how making money off that app, ask yourself why they’d care?

    They’re making money off the app. which suggests they’re selling something they get from the app. (I suppose they could be using your IoT devices to mine crypto when you’re not using it… but that’s got it’s own issues.)


  • This is pathetic.

    I’m glad you enjoy your home connect. A dishwasher shouldn’t need an internet connection to function. Period. Full stop.

    “Just put it on an isolated network” is ridiculous advice, when there shouldn’t even be a need.

    Even if you assume there are no vulnerabilities to find, even if you assume their administrators are never evil, the only reason to require cloud service is to invade my privacy and collect data.

    That’s it. They’re selling your data. Maybe you are fine with that. We are not.
