🛠️ Project Status

I use openhasp-config-manager exclusively to manage my own openHASP devices. While it is my "daily driver", please keep in mind:

• In Development: I’m actively adding tests and refining features to make it more robust.
• Rough Edges: Error logging is still a bit basic. If something goes wrong, the logs might require some "detective work" to figure out the exact cause.
• Experimental: It’s stable for my needs, but since every openHASP setup is unique, you might run into edge cases I haven't hit yet.

If you like the project and want to help polish those error logs or add features, I’m always happy to review an issue or a PR!

Getting Started

openhasp-config-manager is first and foremost a configuration management system. Simply follow the basic folder structure and config deployment will become trivial. Please read all of this, as it is very important to understand the basic structure on which everything relies.

📁 Folder Structure

The following folders should reside inside a single parent folder, f.ex. named openhasp-configs. This folder can be located anywhere you like, but must be accessible to openhasp-config-manager when executing.

• common: The common subdirectory can be used for files that should be included on all device. This folder is optional.
• devices: The devices folder is required. It must contain one subfolder for each openHASP device you want to configure using openhasp-config-manager. It is recommended to name subfolders according to the physical devices associated with them.
  • touch_down_1 (example device folder)
    • A device folder contains *.jsonl, *.cmd and other files which should only be uploaded to that particular device.
    • You can create arbitrary nested folder structures for organizing the files. There is a limit to the file name length though, see FAQ
    • You must provide a config.json file, see config.json for more info.

A more advanced configuration layout could look something like this:

openhasp-configs
├── common
│   ├── content
│   │   └── card.jsonl
│   ├── dialog
│   │   ├── connected.jsonl
│   │   └── offline.jsonl
│   ├── navigation_bar.jsonl
│   └── page_header.jsonl
└── devices
    └── touch_down_1
        ├── 0_home
        │   ├── 0_header.jsonl
        │   ├── 1_content.jsonl
        │   └── page.cmd
        ├── 5_about
        │   ├── 0_header.jsonl
        │   ├── 1_content.jsonl
        │   └── page.cmd
        ├── boot.cmd
        ├── config.json
        ├── offline.cmd
        └── online.cmd

⚙️ Plate Setup (config.json)

openhasp-config-manager makes use of the config.json on your plate by extracting information like the screen orientation. It even allows you to deploy changes within the config.json file.

Note: Since the official API does not support uploading the full file, only settings which can also be set through the web ui on the plate itself are currently supported.

However, the official config.json file doesn't provide enough info for openhasp-config-manager to enable all of its features. To fix that we need to add a custom section to the file.

1. Download your config.json via the openHASP web browser, see official docs.
2. Append the openhasp_config_manager block, adjusting the values as needed.

{
  "openhasp_config_manager": {
    "device": {
      "ip": "192.168.5.134",
      "screen": {
        "width": 320,
        "height": 480
      }
    }
  },
  "wifi": {
    "ssid": "Turris IoT",
    ...
  }
  ... rest of config ...

🧠 Config File Preprocessing

openhasp-config-manager runs all configuration files through various preprocessors, which allow us to use features the original file formats do not support by themselves, like f.ex. templating.

📝 Multiline JSONL files

While the JSONL file format requires each object to be on a single line, openhasp-config-manager allows you to add as many line breaks as you wish. This makes it much easier to edit, since a config like this:

{
  "page": 0,
  "id": 31,
  "obj": "msgbox",
  "text": "%ip%",
  "auto_close": 5000
}

will be deployed like this:

{"page": 0, "id": 31, "obj": "msgbox", "text": "%ip%", "auto_close": 5000}

Comments

Neither JSON nor JSONL allows comments, but openhasp-config-manager does! You can mark comments by prefixing them with a double forward-slash:

// File description
{
  // Object Description
  "page": 0,
  "id": 31,
  // Property Description
  "obj": "msgbox",
  "text": "%ip%",
  "auto_close": 5000
}

🪄 Templating

You can use Jinja2 templates inside all jsonl object values. To access the value of another object in a template, you can use the pXbY syntax established by openHASP, where X is the page of an object and Y is its id. openhasp-config-manager even tries to resolve templates that lead to other templates. Be careful not to create loops in this way though.

You can use the full functionality of Jinja2 like f.ex. math operations, function calls or type conversions.

{
  "page": 1,
  "id": 1,
  "x": 0,
  "y": 0,
  ...
}

  {
    "page": 1,
    "id": 2,
    "x": "{{ p1b1.x }}",
    "y": "{{ p1b1.y + 10 }}",
    ...
  }

📦 Variables & Scoping

Besides accessing other objects, you can also define custom variables yourself, which can then be referenced inside of templates. Variables are defined using *.yaml files. If you decided to use a subfolder structure to organize your configuration files you can use these folders to also set the scope of variables. More specific variable definitions (longer path) will override less specific ones.

Global

Global variables can be specified by creating *.yaml files inside the root config folder (f.ex. openhasp-configs).

Example:

openhasp-configs/global.vars.yaml

about:
  page_title: "About"

To access this variable, use a Jinja2 template:

openhasp-configs/common/about_page.jsonl

{
  "page": 9,
  "id": 1,
  ...
  "title": "{{ about.page_title }}",
  ...
}

Device specific

Device specific variables can be specified by creating *.yaml files inside any of the sub-folders of a device folder.

Note

Device specific variables will override global variables, given the same name.

Example:

openhasp-configs/device/my_device/device.vars.yaml

page_title: "My Device"

openhasp-configs/device/my_device/some_folder/some_page.jsonl

{
  "page": 1,
  "id": 1,
  ...
  "title": "{{ page_title }}",
  ...
}

openhasp-configs/device/my_device/some_other_folder/some_page.jsonl

{
  "page": 2,
  "id": 1,
  ...
  "title": "{{ page_title }}",
  ...
}

Printing variables

If you are not sure what variables are accessible in a given path, you can use the vars command, which will give you a copy&paste ready output of all variables for a given directory:

> openhasp-config-manager vars -c openhasp-configs -p devices/touch_down_1/home
common.navbar.first_page: 1
common.navbar.last_page: 4
...
header.title: Home

🎨 Theming

To specify default property values for an object type, simply define them as a variable under theme.obj.<obj-type>, where <obj-type> is the value of the obj property of the object.

The keys used must conform to the naming of the object properties as specified in OpenHasp, see: https://www.openhasp.com/latest/design/objects/

For example, to make the background color of all buttons red by default, define:

theme.yaml

theme:
  obj:
    btn:
      bg_color: "#FF0000"

in a global variable file named theme.yaml located at the root of your configurations directory openhasp-configs/theme.yaml.

Deployment

To deploy your configurations to the already connected openHASP devices, simply use the generate, upload or deploy commands of openhasp-config-manager.

Note openhasp-config-manager needs direct IP access as well as an enabled webservice on the plate to be able to deploy files to the device. To enable the webservice try: openhasp-config-manager cmd -d plate35 -C service -p "start http"

Run commands

While openhasp-config-manager is first and foremost a config management system, it also allows you to run commands on a device by issuing MQTT messages without the need to install a separate MQTT client first. Note that the MQTT server still needs to be running and also has to be reachable from your local machine for this to work.

For a list of possible commands to send to a device, take a look at the official documentation: https://openhasp.haswitchplate.com/latest/commands/

> openhasp-config-manager cmd -c ./openhasp-configs -d plate35 -C backlight -p "{\"state\":\"on\",\"brightness\":128}"

AppDaemon Integration Utilities

If you want to integrate your openHASP devices with AppDaemon, openhasp-config-manager contains some utilities to make this process easier.

Plate Controller

The OpenHaspController class provides a high-level interface to manage the state of your plate, send commands and listen to events. See: openhasp_config_manager/ad/README.md for more details and examples.

API Client

If you don't want to use all of the file-tree related features of openhasp-config-manager, but still want to interact with your openHASP devices using python and the official API, you can use the OpenHaspClient class to do so. It provides a simple interface to interact with a plate, send commands, listen to events and state updates.

See

• example.py
• example_image.py
• example_jsonl.py

to see how to use it.

FAQ

How do I see device logs?

Try the logs command (this does require network access to the device):

> openhasp-config-manager logs -d plate35

If that doesn't work, open a terminal and run the following command with the device connected via USB cable:

bash -c "screen -q -L -Logfile device.log /dev/ttyUSB0 115200 &> /dev/null; tail -F device.log; killall screen"

Output file name length must not exceed 30 characters

openHASP doesn't support subfolders. To keep your local project organized, the manager flattens your structure during upload (e.g., folder/page.jsonl becomes folder_page.jsonl). So f.ex. the file in the following structure:

openhasp-configs
└── devices
    └── touch_down_1
        └── 0_home
            └── 0_header.jsonl

would be uploaded to the touch_down_1 device with the name 0_home_0_header.jsonl.

To avoid the "Output file name length must not exceed 30 characters" error, make sure that the flattened file name (including the device folder prefix) does not exceed 30 characters.
