This solution requires active WebAPI data binding and can only be properly run via our PlayerConnector. Is not fully functional in the built-in SceneComposer player.
To run the solution with the player connector in **simulation environment** the following steps have to be executed: - [Generate the simulation asset](https://doc316en.candera.eu/books/asset-library-generation/page/generate-asset-library) of the Pollen Infoscreen Sample Solution and save it in *<cgi-studio-installation-path>\\bin\\CommunityEdition\\Python\\Samples\\PollenInfoScreen* - Obtain the API Key from [Polleninformation Datenschnittstelle / API | Polleninformation](https://www.polleninformation.at/datenschnittstelle). Use the [contact form](https://www.polleninformation.at/datenschnittstelle/api-key-anfordern) to request an API Key. - After receiving your API key, replace "PUT\_YOUR\_APIKEY\_HERE" with your API key on line 276 of the script ***<cgi-studio-installation-path>\\bin\\CommunityEdition\\Python\\Samples\\PollenInfoScreen\\PollenInfoScreen.py***, as seen below. [](https://doc316en.candera.eu/uploads/images/gallery/2026-07/image-4.png)If the API Key is not set, you are still able to run the solution, but the information will not be updated.
- Before executing the Python script, open a command prompt in *<cgi-studio-installation-path>\\bin\\CommunityEdition\\Python\\Samples\\PollenInfoScreen* and, if it is not already installed, install the CanderaAppConnector Python library using: ``` python -m pip install ..\..\ ``` - Execute the python script *<cgi-studio-installation-path>\\bin\\CommunityEdition\\Python\\Samples\\PollenInfoScreen\\PollenInfoScreen.py* **Example usage:** ``` python PollenInfoScreen.py ^ -lbp ..\..\..\RaspberryPi_Simulation\PlayerConnector\PlayerConnectorLibrary.dll ^ -abp PollenInfoScreen.bin ``` **Parameters:** - **-lbp** (Library Binary Path) Path to the **PlayerConnector** library ```To run it on the Target please follow the steps from [Run Sample with Player Connector Library.](https://doc316en.candera.eu/link/1358#bkmrk-run-blood-pressure-s-1)
#### Overview scene: The overview scene features the most important information at one glance. Via clicking the location (in this case Vienna) the user can select different countries and cities. In the top left corner the overview scene shows the general allergy risk (depending on the strongest contaminant that day) and shows the forecast for the upcoming 3 days as well in the box next to it. [](https://doc316en.candera.eu/uploads/images/gallery/2026-07/image-2.png) In the left bottom corner the forecast for the day is shown on a more granular level in 4-hour intervals. In addition to the general information the users can set up to 4 individual contaminants to also have the most relevant ones available at a glance. **Dynamic Elements:** - Clock control - Air Quality – text value - DayRisk control (4 week days) - MultihourValue control (bars with 10 levels/images) - Pollen\_Brief control (level of preselected contaminant, with 4 levels, triggers list of contaminants) - City Button (triggers location list) - Insights Button (switches to contaminants list scene) #### Insights scene The insights scene features a list of up to 8 available contaminant information available via WebAPI. The list hierarchy is taken over from the WebAPI data and is usually ranked by strongest to weakest contaminant (with the strongest contaminant on the top of the list).
