Readings of a sensor

GEThttps://api.atmy.ai/v1/sensors/{id}/readings

Raw readings or 5-minute means (interval=5min) of the last 31 days, up to 7 days a request, or hourly means (interval=hour) of the last 366 days, up to 92 days a request, or daily means (interval=day) with the check of each day, up to a year a request

Path parameters

id string required

Sensor id, as in the list of sensors.

Query parameters

interval string optional

raw, 5min, hour or day.

Default: raw

from string optional

Start, ISO 8601 or Unix seconds, UTC.

to string optional

End, ISO 8601 or Unix seconds, UTC; by default now.
