INDI Web Manager

INDI Web Manager is a simple Web Application to manage:

It supports multiple driver profiles along with optional custom remote drivers. It can be used to start INDI server locally, and also to connect or chain to remote INDI servers.

INDI Web Manager

The Web Application is based on Bottle Py micro-framework. It has a built-in webserver and by default listens on port 8624.

Installation

Before installing the indiweb package, make sure the INDI library is installed on the target system.

You can install the indiweb Python package using pip:

$ pip install indiweb

You may want to install it system-wide, only in your user account or even into a virtual environment (if you are a developer).

If you want to install it system-wide, you will have to invoke pip with superuser rights:

$ sudo pip install indiweb

Usage

After installing the indiweb package, the command indi-web will be available in your sytem PATH.

You can obtain help about the indi-web command by invoking:

$ indi-web -h

The INDI Web Manager runs as a standalone web server. It can be started manually by invoking:

$ indi-web -v

Then using your favorite web browser, go to http://localhost:8624 if the INDI Web Manager is running locally. If the INDI Web Manager is installed on a remote system, simply replace localhost with the hostname or IP address of the remote system.

Auto Start

If you selected any profile as Auto Start then the INDI server shall be automatically started when the service is executed at start up.

Auto Connect

Similary to Auto Start, Auto Connect would connect all the drivers after the server is up and running.

Start vs. Connect

What is the difference between starting a driver and connecting a driver?

  • Start: The INDI server executes the driver. The driver starts up and provide a list of properties. It does not establish connection with the physical device.
  • Connect: Establish connection to the physical device.

Systemd configuration

The provided file indiwebmanager.service is an example systemd service file that can be used to run indi-web at startup as pi user. If your username is different please edit the file and change the username first.

Indiwebmanager must be installed system-wide:

sudo pip install indiweb

Copy your preferred service file to /etc/systemd/system:

sudo cp indiwebmanager.service /etc/systemd/system/
sudo chmod 644 /etc/systemd/system/indiwebmanager.service

Now configure systemd to load the service file during boot:

sudo systemctl daemon-reload
sudo systemctl enable indiwebmanager.service

Finally, reboot the system for your changes to take effect:

sudo reboot

After startup, check the status of the INDI Web Manager service:

sudo systemctl status indiwebmanager.service

If all appears OK, you can start using the Web Application using any browser.

Profiles

The Web Application provides a default profile to run simulator drivers. To use a new profile, add the profile name and then click the plus button. Next, select which drivers to run under this particular profile. After selecting the drivers, click the Save icon to save all your changes. To enable automatic startup of INDI server for a particular profile when the device boots up or when invoked manually via the systemctl command, check the Auto Start checkbox.

API

INDI Web Manager provides a RESTful API to control all aspects of the application. Data communication is via JSON messages. All URLs are appended to the hostname:port running the INDI Web Manager.

INDI Server Methods

Get Server Status

URL Method Return Format
/api/server/status GET INDI server status (running or not) {'server': bool, 'active_profile': profile_name}

/api/profiles/<name> DELETE None None

To delete a profile named foo:

curl -X DELETE http://localhost:8624/api/profiles/foo

Get All Profiles

URL Method Return Format
