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)

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
