-Request API
-
-Welcome! This page documents the usage of the internal meteo Request API
-The request API supports the following main items:
-
-
-
-Stations
-
-The link /stations serves an overview of the known stations for the system
-The output is a commented CSV of the following format:
-
-
-# Id,Name,Location,Description
-1,test,virtual,Test station 1
-
-
-
-Station
-
-/station/id is there to request informations from a specific station, identified by it's id.
-
-The following request types exist:
-
-- /station/id Fetch current readings as CSV (e.g. /station/1)
-- /station/id/year.csv Fetch the data of the given year as CSV (e.g. /station/1/2019.csv)
-- /station/id/year/month.csv Fetch the data of the given year and month as CSV (e.g. /station/1/2019/08.csv)
-- /station/id/year/month/day.csv Fetch the data of the given year, month and day as CSV (e.g. /station/1/2019/08/02.csv)
-
-
-
-Current Readings
-
-The link /current serves the current readings as CSV
-/current.csv servers the current readings as CSV file
-
-The output of /current looks like the following:
-
-
-# Station, Timestamp, Temperature, Humidity, Pressure
-1,1562242860,24.10,9.00,94388.00
-
-
-
-MQTT
-
-meteod can be configured, to use MQTT.
If a MQTT channel is configured, meteod connects to the broker and listens on the meteo/# channel for messages
-
-
-A typical message is JSON formatted and looks like the following
-
-{"node":5,"name":"Lightning","t":20.41,"hum":70.51,"p":95409.73}
-{"node":5,"name":"Lightning","t":20.41,"hum":70.48,"p":95410.53}
-{"node":1,"name":"Kitchen","t":27.97,"hum":48.60,"eCO2":400.00,"tVOC":0.00}
-
-
-
-
-If a MQTT broker has been defined and meteod received data via HTTP, it also pushes them as JSON to MQTT.
-
-
-
-MQTT is considered as trusted channel. If a new station appears via MQTT, meteod inserts the station into the database. For more control and protection against missuse, please use http!
