Start with the workbench if you came for notifications — token in, phone buzzing, recipes out, about a minute. The room is where the identity side lives: six things a login usually can't do, listed below, all of them real. And Hearth works before you install anything at all.
An identity that exists only between you and one site.
Come back tomorrow, or on a computer that has never seen you.
The site tells you something while the tab is closed.
Something irreversible asks your phone first.
Tap the notification, land on the right page, already signed in.
End the relationship. Every route back dies at once.
Paste a token. Press a button. Feel your pocket. Then flip the priority to +2 and see what "gets past quiet hours" means, and make a script block on your own approval — fingerprint and all.
Leaves with you: working, copy-paste recipes for curl, Uptime Kuma, Home Assistant and GitHub Actions, with your token already filled in.
One public channel. Reading is open to anyone; speaking needs a name the room can hold you to — and that name is the only thing it ever gets. No email, no phone number, no password, nothing to reset.
This one is live. Real messages, real people, and a real notification when someone mentions you while the tab is closed. If you are early, the room may be empty; that is what early looks like.
A home hub with no identity in it anywhere. The washing machine finishes, the freezer starts warming up, and the front door has been unlocked for twenty minutes — so it asks whether to lock it, and wants a fingerprint before it will.
Underneath, on the same page: the Home Assistant automation, the curl, the token, and every call the page just made.
Runs against a simulated phone by default, so you can try it before installing anything. One button switches it to your real device.
Which one you get is decided by what the service sends, never by a flag it can set — otherwise a marketing push could dress itself up as an approval and win the buttons, the urgent channel and a quiet-hours bypass.
The only kind that ever gets buttons, because a decision is the thing that deserves a fingerprint. A service can demand a real owner check — and a phone with no lock can still deny, it just can't approve.
No buttons. Tapping opens that page on the service's own site, already signed in as your pairwise identity, at the exact thing that needs an answer.
Your washing is done. Your report was received. It opens in the Lauther app and that is the whole story.
