I've never seen (or heard I guess) a kettle with a status alarm. They tend to be pretty loud when they're on, you know the water is boiled because they actually do the opposite of an alarm, the sound of boiling water gets quieter.

Maybe thats not calm tech because it requires me to listen out for it, but its simple enough and does the job

Have you used a whistling tea kettle? I think that's what they're referring to -- there's a small opening in the lid or spout of the kettle, and when enough steam pressure builds up inside, the steam forces itself through the opening and makes a loud whistling sound.

I've only ever seen them in cartoons, didn't even clock they were a real thing until I read that

They are real and common and good, but I don’t consider the sound they make all that calming.

I use an insta hot dispenser to make tea. Virtually silent hot water on demand. That seems calmer to me.
