Home Assistant notification listing Braun measurements to attribute

How it works

Take a reading. It is already there.

Home Assistant connects as soon as the device wakes up and stays with it while it is on, through any Bluetooth adapter or ESPHome Bluetooth proxy.

Measure as usual

Use the thermometer or the monitor exactly as before. Nothing to press, no phone to unlock.

Synced live

Each reading arrives within a second, with its real time. Readings taken out of range come in at the next power-on.

History that makes sense

Per-person sensors and long-term statistics, dated when the reading was taken, not when it was filed.

People

Who was it for?

A thermometer cannot tell who was measured, so its readings wait to be attributed. A blood pressure monitor knows its user buttons and routes readings by itself.

On your phoneOne notification per reading, with a button per person.
In Home AssistantWaiting readings are listed in notifications and filed from the device page, even the next day.
AutomaticallyButtons A and B of a monitor go straight to their person; a shared button asks every time.

Setup

Ready in under a minute.

Devices are discovered on their own. Thermometers pair with the six-digit PIN they display; blood pressure monitors need no pairing at all. People are declared in the same flow.

A named buttonsends its readings straight to that person.
A button without a nameasks among everyone declared: a shared monitor, a guest.
Phones listed by nameare only notified for readings that wait to be attributed.
