GTFS Clean

Removes unneeded stops in a GTFS database for faster usage in Home Assistant

Credit

Renemarc did the hard work of detailing what needed to be done.

Installation

This app is best installed using HACS, so that you can easily track and download updates.

Alternatively, you can download the cleangtfs directory from inside the apps directory here to your local apps directory, then add the configuration to enable the cleangtfs module.

How it works

When a transit group releases a new gtfs.zip for their network, A number of manual steps are required for Home Assistant to most effectively use the new data. As described by Renemarc there will be a efficiency problem due to most people only requiring a few stops from the network of any transit group, therefore removing all the unneeded stop information can speed up your system.

While this is an irregular occurance, I found that my local transit group was releasing over 4 new files a year, making me redo the delete and index processes, and I needed to write myself a process to complete each time. This app removes the need to complete the manual steps.

Note: That you can have multiple transit systems in HA, just rename each zip file to something appropriate.

Download your GTFS zip file from Open Mobility
Delete any earlier gtfs.zip and gtfs.sqlite related files in the /config/gtfs directory of Home Assistant
Place the new zip file into the /config/gtfs directory of Home Assistant
Restart Home Assistant - this will build a new sqlite database from the zip file
This app will complete the manual deletes, updates and build the indexes described by Renemarc
Restart Home Assistant

To Run

You will need to create an entity for each gtfs database in use (see below to pass the name). When this input_boolean is turned on, whether manually or by another automation you create, the clean up process will be run on the GTFS file named in apps.yaml.
