Data acquisition in a nutshell#
Data is usually ingested through MQTT . However, ingesting data using HTTP  is also possible by adding a configuration object like outlined within HTTP acquisition API configuration.
A minimal example of how to publish data using MQTT is:
mosquitto_pub -h localhost -t mqttkit-1/testdrive/area-42/node-1/data/temperature -m '42.84'
A minimal example of how to submit data using HTTP is:
http POST http://localhost:24642/api/mqttkit-1/testdrive/area-42/node-1/data temperature:=42.84
Please follow the documentation to read more details about data acquisition through MQTT and HTTP.
Data acquisition using MQTT for transmitting telemetry data over MQTT from other environments (Python, Arduino, mbed).
Data acquisition using HTTP for transmitting telemetry data over HTTP.
See Basic example with MQTT for submitting measurement values / telemetry data from the command line.
For sending a simple oscillating signal to Kotori from the command line, please have a look at the Single sawtooth signal page.
