How it works

From a thought on the bus to a note at the door.

There are two halves: a small display that sits by your door, and a web page you open on your phone. They talk to each other so you do not have to.

The device watches one thing

A small magnetic sensor goes on the door frame, with its partner on the door itself — the same kind of switch used in home alarm systems. It knows one fact: whether the door is currently open or closed.

That single fact is enough. When the door opens and there is something waiting for you, the screen lights up and shows it. When there is nothing waiting, the screen stays dark and the device does nothing at all.

The sensor sticks on. No drilling, no wiring into the door.

Two kinds of reminder

They share one screen and behave differently on purpose.

Quick reminders — sent from your phone

One-off notes for a specific moment. Type up to 48 characters, tap Add, and it shows the next time the door opens. Anyone in your household with an account on the device can send one.

You can hold up to 20 waiting at once. If you reach that, the site refuses the next one and tells you why rather than quietly dropping it — a reminder you thought you sent and never arrived is the worst thing this product could do.

Routines — set on the device itself

Recurring checklists tied to days and times: the school-morning list, the gym bag on Tuesdays and Thursdays, bins on Wednesday night. You build these on the touchscreen and then never think about them again.

When both are due at once, the quick reminder shows first. It is the one that is time-sensitive.

At the door

Two buttons, because the door cannot tell whether you are coming or going.

Got it

You have dealt with it. The reminder is finished and disappears from your phone as done, so whoever sent it can see that it landed.

Later

You are walking in the door, not out of it — or you are only going to the car for thirty seconds. The reminder stays armed and comes back on a later opening, after a short pause so it does not nag you twice in a row.

Walk away without touching either one and it counts as Later. A reminder can never be lost by ignoring the screen.

Setting it up

About 5 minutes, once, and no app to install.

  1. 1

    Plug it in

    USB-C into any phone charger. Stick the sensor on the door frame and its magnet on the door, level with each other.

  2. 2

    Give it your Wi-Fi

    The device creates its own temporary network called OHryte-XXXX. Join it from your phone, pick your home network from the list, type the password. The device tests it before saving, so you find out immediately if the password was wrong.

  3. 3

    Link it to your account

    The screen shows an eight-character code. Sign in at ohryte.com, type the code, and the two are paired. The code expires after ten minutes and can only be used once.

Needs 2.4 GHz Wi-Fi (802.11 b/g/n). Most home routers broadcast both 2.4 GHz and 5 GHz; the device only uses the first.

The first batch is small and the waitlist is how it gets allocated. It costs nothing to join.
