File++

Based on the Home Assistant Core Integration File, I created a custom version that reads and writes multi-line content.

Use case examples:

• Store and read data larger than 255 characters
• Load email HTML templates
• Store large AI/ChatGPT responses
• ... and much more!

Features:

• Use the notify service to write multi-line content to a local file. If a file already exists, its content will be erased and the new content will be stored
• Use the sensor service to read multi-line content from a local file. The content is available in the content attribute of the sensor.

Removed:

• State of the sensor no longer holds the content of the file. Shows 'Ok' (for now :) ).
• No header is written to empty/new files

Notes:

• ⚠︎ I have not limited the size of the filesize for the sensor service. On a dev setup I successfully read the 10M (Studenten Net Twente FTP) file. The 1000M ended up in a crash-reboot loop from HA.

Installation

Install via HACS (recommended)

Waiting on HACS to be added. In the meantime, this repo can be added as custom repository

Manual install

1. Download the latest release of the File++ from this repository;
2. In Home Assistant, create a folder config/custom_components;
3. Add the File++ files to the custom_components folder (you should end up it with a config/custom_components/file_plusplus folder);
4. Restart Home Assistant;
5. Add a File++ entity as an Integration in Home Assistant (menu: settings -> devices & services -> add integration);

For updates, repeat step 1 to 4. Home Assistant will not delete any configuration.

Configuration

Configuration is done the same as the Home Assistant Core Integration File
