There already exists "kinetic" switches for lights etc whose switch contains some passive electronics that when actuated produces enough energy to emit a radio signal that can be read by a relay module. They're pretty handy as you can basically place the switch anywhere you want without the need for the wires to be there. The relay can live in the light fitting or somewhere else convenient.

There's probably no reason why these kinetic switches can't also be used for detecting other events like doors opening/closing etc. I feel like a radio signal is a bit more reliable and easier to detect than high frequency sound.

I also think calling these a "sensor" is a bit of a stretch. They detect events but have no knowledge of the current state of the thing they're sensing. E.g. the can detect a door opening/closing, but have no idea if the door is open or closed at a given time

Interesting to see Spain having such low IPv6 adoption. Perhaps that's exacerbated the issues caused there by blocking IPs during football matches that we've seen mentioned in recent HN posts.

Are you with SFR? I also seem to only have a static IPv4 (I don't pay for it, but it's never changed in the lifetime of the connection). I asked for an IPv6 but they said it was not possible/difficult.

The other replies answer this question, but it’s worth mentioning the public suffix list which contains a list of domain suffixes that have subdomains that are controlled by different people. E.g github.io, wordpress.com

Browser use this list to prevent cookie shared between sites using the suffixes on the list. E.g evil.github.io will not receive cookies from nice.github.io, or any other .github.io origin, regardless of the SameSite attribute

No, because unlike a password you never provide the private key for a passkey to the site you’re logging into, which is how many password breaches occur.

Or putting `|> dbg()` at the end and let it print the value at every step of the chain

It's not clear text by default, it's just not end-to-end encrypted. Messages are still encrypted between client and server.

I agree about considering alternatives though.

I wonder if it would be possible to figure out which pins are connected to what on the device's board and just flash the thing completely with ESPHome and write a custom yaml config for it, rather than adapting the existing vendor firmware.

You get more heat out of using a given quantity of gas to generate electricity which is used to to power a heat pump than you do by burning the gas directly for heat, even when considering generation and transmission losses etc.

Given that even during a time of low output from renewables we still only rely on 53% gas for electricity generation it's still much more beneficial environmentally to use a heat pump.

The monetary cost is another story though, and I agree we do need to work on weaning ourselves off gas.

Hinckley point C is under construction in the uk and on track for 2026 opening

Edit: potentially delayed by some years

I don't think customers not caring is a valid reason to not do this. Compromised IoT devices don't only cause harm to their owners, but also external networks and the internet as a whole.

A compromised doorbell, or lightbulb etc can be used as part of a botnet to perform DDoS attacks or other nasty activities.

An analogy is like saying we shouldn't work on reducing the pollution emmitted by motor vehicles because the users of these vehicles don't care about how much pollution they cause and would buy them regardless. It's the negative externalities that we need to consider.

> SMS is the only second factor that works for people without smartphones.

That's not correct. Many password managers have TOTP authentication features built in.

There's also increasing support for security keys (e.g. yubikey) with many websites.

Passkeys are also on the rise.
