#iothub-explorer A sample CLI tool to manage device clients using the Azure IoT Hub service SDK. The tool enables you to manage the devices in the identity register, monitor device-to-cloud messages, and send cloud-to-device commands.
## Installing iothub-explorerNote: This tool requires Node.js version 4.x or higher for all features to work.
To install the latest (pre-release) version of the iothub-explorer tool, run the following command in your command-line environment:
npm install -g iothub-explorer@latest
You can use the following command to get additional help about all the iothub-explorer commands and their parameters:
$ iothub-explorer help
Supply your IoT Hub connection string once using the login command. This means you do not need to supply the connection string for subsequent commands for the duration of the session (defaults to one hour):
$ iothub-explorer login "HostName=<my-hub>.azure-devices.net;SharedAccessKeyName=<my-policy>;SharedAccessKey=<my-policy-key>"
Session started, expires Fri Jan 15 2016 17:00:00 GMT-0800 (Pacific Standard Time)
Note: See Set up IoT Hub for information about how to retrieve your IoT Hub connection string.
To retrieve information about an already-registered device from the device identity registry in your IoT Hub, including the device connection string, use the following command:
$ iothub-explorer get known-device --connection-string
-
deviceId: known-device
...
-
connectionString: HostName=<my-hub>.azure-devices.net;DeviceId=known-device;SharedAccessKey=<known-device-key>
To register a new device and get its connection string from the device identity registry in your IoT Hub, use the following command:
$ iothub-explorer create new-device --connection-string
Created device new-device
-
deviceId: new-device
...
-
connectionString: HostName=<my-hub>.azure-devices.net;DeviceId=new-device;SharedAccessKey=<new-device-key>
To delete a device from the device identity registry in your IoT Hub, use the following command:
$ iothub-explorer delete existing-device
Use the following command to monitor the device-to-cloud messages from a device:
$ iothub-explorer 'HostName=<my-hub>.azure-devices.net;SharedAccessKeyName=<my-policy>;SharedAccessKey=<my-policy-key>' monitor-events myFirstDevice
Monitoring events from device myFirstDevice

Note: The monitor-events command requires you to provide the IoT Hub connection string even if you have created a session using the login command.
Use the following commands to send a cloud-to-device command and then wait for the device to respond with an acknowledgment:
$ iothub-explorer send myFirstDevice MyMessage --ack=full
