Room climate

Room climate

A room's name, its temperature in large digits, the humidity, and when it changed. It fits a tag on the wall next to a thermostat, or one per room.

The layout room-climate comes from the designer's template library: + From template → Home → Room climate, then Send to your AP.

        {{ ['Living room',
            ('%g' | format(((t * 2) | round(0)) / 2)) | replace('.', ','),
            ((h / 5) | round(0) * 5) | int,
            'Since ' ~ now().strftime('%H:%M')] }}

The tag shows, for example, Living room, 21,5 °C (or 22 for a whole degree), 45 % and Since 14:05.

The condition is what keeps the battery going: a temperature sensor reports every few tenths of a degree, and without it the tag would be redrawn for each one. With half degrees and 5 % steps it is redrawn a few times a day. The time in the last field only changes when a value does, so it says when the room last changed, not when the tag was last drawn.
