Python REST Client

Python REST Client

The ThingsBoard Python REST API Client helps you interact with ThingsBoard REST API from your Python script. With Python Rest Client you can programmatically create assets, devices, customers, users and other entities and their relations in ThingsBoard.

Source code of the Python REST API Client you can find here.

In order to install the ThingsBoard Python REST client, you should use the following command:

1

pip3 install tb-rest-client

Python REST Client examples

Basic usage

You can find the example script here.

The example listened below shows basic usage of REST client, namely how to perform a login, create a new Asset and Device instances, and how to establish relationships with them.

Configure version control feature from console

This feature is available in ThingsBoard 3.4+. We have designed script, based on tb-rest-client library to make example how to use ability to configure ThingsBoard from your code.
The latest source code of the script is available here. In this example we configure version control feature on ThingsBoard.

There are 2 possible ways to configure version control system (VCS):

  1. Using access token/password of your VCS account.
  2. Using private key.

Configuring version control system using access token or password

To configure this feature we will need the command line arguments and data:

Command line argument Description
-H ThingsBoard host (Default: localhost)
-p ThingsBoard port (Default: 80)
-U ThingsBoard user (email for login)
-P ThingsBoard user password
-r Repository uri, link to your repository
-b Default branch (Default: main)
-gu VCS username (This parameter named GITHUB_USERNAME, but it can work with any VCS)
-gp VCS access token / password (This parameter named GITHUB_PASSWORD, but it can work with any VCS)

You always can get the full list of arguments by calling script with no arguments or with -h argument.

To configure the version control feature we should have installed tb-rest-client python package and download the script:

1

wget https://github.com/thingsboard/thingsboard-python-rest-client/blob/master/examples/configure_vcs_access.py

Now we can run the script and configure version control feature (Do not forget to put your values).

1

python3 configure_vcs_access.py -H YOUR_THINGSBOARD_HOST -p YOUR_THINGSBOARD_PORT -U YOUR_THINGSBOARD_USER_EMAIL -P YOUR_THINGSBOARD_USER_PASSWORD -r YOUR_REPOSITORY_URL -b DEFAULT_BRANCH -gu YOUR_VCS_USERNAME -gp YOUR_VCS_ACCESSTOKEN_OR_PASSWORD

Configuring version control system using private key

To configure this feature we will need next command line arguments and data:

Command line argument Description
-H ThingsBoard host (Default: localhost)
-p ThingsBoard port (Default: 80)
-U ThingsBoard user (email for login)
-P ThingsBoard user password
-r Repository uri, link to your repository
-b Default branch (Default: main)
-gu VCS username (This parameter named GITHUB_USERNAME, but it can work with any VCS)
-pk Path to private key
-pkp Password for private key (If it was set)

You always can get the full list of arguments by calling script with no arguments or with -h argument.

To configure the version control feature we should have installed tb-rest-client python package and download the script:

1

wget https://raw.githubusercontent.com/thingsboard/thingsboard-python-rest-client/master/examples/configure_vcs_access.py

Now we can run the script and configure version control feature (Do not forget to put your values).

1

python3 configure_vcs_access.py -H YOUR_THINGSBOARD_HOST -p YOUR_THINGSBOARD_PORT -U YOUR_THINGSBOARD_USER_EMAIL -P YOUR_THINGSBOARD_USER_PASSWORD -r YOUR_REPOSITORY_URL -b DEFAULT_BRACH -gu YOUR_VCS_USERNAME -pk PATH_TO_YOUR_PRIVATE_KEY -pkp YOUR_PRIVATE_KEY_PASSWORD

Saving all entities to version control system

You can use the following script, based on tb-rest-client to save current state of your entities to your repository on version control system.

The latest source code you can find here.

To save entities from command line we will use the following arguments and data:

Command line argument Description
-H ThingsBoard host (Default: localhost)
-p ThingsBoard port (Default: 80)
-U ThingsBoard user (email for login)
-P ThingsBoard user password
-b Default branch (Default: main)
-N Version name (If not provided will be generated 5 random letters and numbers and used as a name)
–save_attributes Optional, do we need to save attributes for target entities (Default: True)
–save_credentials Optional, do we need to save credentials for target entities (Default: True)
–save_relations Optional, do we need to save relations for target entities (Default: True)
–sync_strategy Optional, Sync strategy for entities can be OVERWRITE and MERGE (Default: MERGE)

You always can get the full list of arguments by calling script with no arguments or with -h argument.

Let’s download the script:

1

wget https://raw.githubusercontent.com/thingsboard/thingsboard-python-rest-client/master/examples/load_all_entities_to_vcs_ce.py

Now we can run our script and save our entities to the repository on version control system, we will publish to default branch with default settings to show minimal required configuration:

1

python3 load_all_entities_to_vcs_ce.py -H YOUR_THINGSBOARD_HOST -p YOUR_THINGSBOARD_PORT -U YOUR_THINGSBOARD_USER_EMAIL -P YOUR_THINGSBOARD_USER_PASSWORD

In output message you will receive information about how many entities were saved.

Loading all entities from version control system

You can use the following script, based on tb-rest-client to save current state of your entities to your repository on version control system.

The latest source code you can find here.

To load entities from command line we will use the following arguments and data:

Command line argument Description
-H ThingsBoard host (Default: localhost)
-p ThingsBoard port (Default: 80)
-U ThingsBoard user (email for login)
-P ThingsBoard user password
-b Default branch (Default: main)
-N Version name (You can provide a part of the version name and script will propose you all find versions that include provided name)
–load_attributes Optional, do we need to load attributes for target entities (Default: True)
–load_credentials Optional, do we need to load credentials for target entities (Default: True)
–load_relations Optional, do we need to load relations for target entities (Default: True)
–sync_strategy Optional, Sync strategy for existing entities can be OVERWRITE and MERGE (Default: MERGE)

You always can get the full list of arguments by calling script with no arguments or with -h argument.

Let’s download the script:

1

wget https://raw.githubusercontent.com/thingsboard/thingsboard-python-rest-client/master/examples/load_all_entities_from_vcs_ce.py

Now we can run our script and restore entities version and state from the repository on version control system:

1

python3 load_all_entities_from_vcs_ce.py -H YOUR_THINGSBOARD_HOST -p YOUR_THINGSBOARD_PORT -U YOUR_THINGSBOARD_USER_EMAIL -P YOUR_THINGSBOARD_USER_PASSWORD -N YOUR_VERSION_NAME

In output you will receive information about how many entities were loaded.

The Professional Edition Python REST Client example you can find here.
