iobeam Command-line Interface
iobeam is a data platform for connected devices.
This is a Command-line Interface (CLI) for the iobeam API. For more information on the iobeam API, please read our full API documentation.
Please note that we are currently invite-only. You will need an invite to generate a valid token and use our APIs. (Want an invite? Sign up here.)
Included with each release are binary executables
for OSX (darwin), Linux, and Windows. This is the easiest way to use the
CLI: simply download the one that corresponds to your platform, rename it
iobeam, and make sure it is executable.
For OSX users, it is also available via Homebrew:
$ brew tap iobeam/tap $ brew install iobeam
Building and installing from source
You’ll need to install Go (e.g.,
brew install go on
Mac OSX). Make sure your
GOPATH is set (e.g.,
We recommend using the latest version of Go, but at least version 1.4.3.
Older versions may have problems.
$ go get github.com/iobeam/iobeam
On first run, a dot directory,
.iobeam, is created in your home
directory to store state such as user and project tokens which authenticate you to the iobeam cloud.
Creating your first project and device
# Register as a new user, this will automatically log you in. $ iobeam user create -email="<email>" -password="<password>" -invite="<invite_code>" # Optionally, if you have an account already, you can just login. # You will be prompted for your credentials $ iobeam user login # Create a new project. Project name must be globally unique. # You will be given a project ID (keep track of it), and a # project token will be stored. $ iobeam project create -name="<project_name>" # Create a new device. (Keep track of the device_id that the API returns.) $ iobeam device create -projectId=<project_id>
You can send single data row via the CLI. Timestamps are expressed as milliseconds since epoch.
# Send data row with temperature=72 and humidity=54 with the current time $ iobeam import -fields=temperature,humidity -values=72,54 -labels device_id=<deviceId> # Send data row for time 1429718512829 (epoch time). $ iobeam import -fields=temperature,humidity -values=72,54 -labels device_id=<deviceId> \ -time=1429718512829 # Optionally, you can specify the -projectId (defaults to current project) $ iobeam import -projectId <projectId> -labels device_id=<deviceId> \ -fields=temperature,humidity -values=72,54
You can also refer to our Imports API.
Note: All of these commands require that you first create a valid project token with read access. This will be created when you create the project, however if this does not work for some reason, see the next section.
# Query the last 10 data rows for a project $ iobeam query -projectId=<project_id> # You can also leave off -projectId, which will use the projectId of the # last project you got a token for. # The limit on the number of rows can be changed from its default of 10 $ iobeam query -limit 1000 # Query the last 10 data rows for a given device $ iobeam query -where "eq(device_id,<device_id>)" # Query the last row for each device (up to 1000 total rows) $ iobeam query -limitBy "device_id,1" -limit 1000 # Query a specific data field under a given project and device $ iobeam query -where "eq(device_id,<device_id>)" -field="<field_name>" # Query the last 1000 data rows over the last day $ iobeam query -last="1d" -limit 1000
The REST API also supports richer queries with operators (e.g.,
max), date / value
ranges, time-series rollups, and more. Please refer to our Exports API
for more information.
Creating additional project tokens
When you create a project, the token you are given has admin privileges, which you will not want to distribute with devices going to third parties. Instead, you can generate a new token that allows you to upload data (i.e. has write permissions) but not admin permissions.
# Generating a read/write only token $ iobeam project token -id=<project_id> -read=true -write=true -admin=false # Generating a write only token $ iobeam project token -id=<project_id> -read=false -write=true -admin=false
