You're right in that it's a useful tool for various kinds of abuse, but so is almost every useful home automation/home security sensor.
The most obvious/useful use cases I can see are:
Both should be easy with load cells under the bed legs but rather difficult otherwise.
(Useful assuming a household of two adults in one bed that is).
Is dumb doorbell + separate CCTV camera a valid alternative? Even my fairly basic Reolink camera has a much better image quality than any doorbell camera I've seen, and HA can pull an image from it and push it to my phone in only a few tenths of a second whenever someone pushes the doorbell.
You're right in that running HA just for a WoL timer would be silly, but (presumably) it's already running for other, less silly purposes.
I'd say the main benefit is when the machine requires regular (as in daily) reboots, or if it's something you don't trust is fully private and want to be powered off outside work hours. Not useful for me, but I can see why it would be handy.
I remember seeing someone combine the two and had Home Assistant pull the photograph from USPS and attaches it to the notification when the mailbox sensor is triggered.
If I remember correctly, they are allowed to have a thumb throttle if it's capped at 6km/hr (which is still very handy for starting, especially on a cargo bike). On a generic Bafang/similar motor controller, that's a purely software limit that anyone with a programming cable can change.
I'm in the same boat - zero ads in Sync for Lemmy until this last update. I just assumed the purchase from Sync for Reddit had carried over, but I guess either LJ changed his mind or it wasn't intentional.
I'm mildly surprised OP's laptop keeps the bluetooth radio powered up while asleep, but I would be a lot more surprised to find one that doesn't work with USB HID.
Node Red by far gave me the best automation for numerous lights. X minutes after sunrise, it iterates every light that is on and calls turn off with a fairly long (2 min?) transition time, so the lights all gradually fade off.
It's been running for years without me needing to touch anything, it doesn't care if you replace/rename any lights, and the slow fade when it's still getting brighter outside makes the change invisible.
I'll bet you could do the same thing without Node Red, but nowhere near as easily.
That isn't even a terrible idea - with that many conductors, you should be able to carry tens of amps. Use two for "Data" (detecting charger) and you've got... 21 positive and 21 negative. I'd not be surprised to see that hit 100W without catching fire.
How many people actually want curved walls though?
People who hire fancy architects. Not people who have to work for a living.
It depends on what you're building. If you want a normal rectangular house, 3D printing will be incredibly inefficient and pointless compared to traditional framing techniques.
On the other hand, if you want curved walls, traditional framing becomes incredibly complex and expensive, whereas 3D printing takes exactly the same materials and labour regardless.
I think 3D printing an entire house is just a gimmick, but it will still be an incredibly useful tool, even if only used for simple things like making rounded foundation pads or retaining walls that follow the landscape or curved hallways connecting modular buildings.
As long as the punishment is fair and not unduly harsh, I don't see any real problem with criminalising misinformation in general. It's already illegal to lie about facts in a great many contexts (e.g. fraud, perjury), and reasonable people don't have a hugely difficult time distinguishing a fact from an opinion.
As a trivial example: "This is mine and you can have it for a dollar" is not an opinion someone can be entitled to, it is a statement of fact that is either true or not.
