Readings dictionary

Each reading has a code. The code is the same in all languages. You see it in the API.

The Name in the app column shows the name in the English app.

Note

The app changes the scale of the unit automatically, for example from W to kW. You set the temperature unit in the preferences. See Language, theme, units.

You can change the name of a reading in the device settings. Then the app shows your name.
