#### Extending functionality
You're not limited to just the nodes we've created. Enable global access in your Matrix Client to directly interact with the client from function nodes and create custom logic.
- This module doesn't handle encryption key synchronization between devices. It’s recommended to use the bot exclusively in Node-RED to prevent issues with E2EE messages.
- Storage: Keys for E2EE are saved in a folder called matrix-client-storage within your Node-RED directory. Back up this folder regularly! If lost, you won’t be able to decrypt messages from E2EE rooms.
- To move your bot to a different installation, migrate this folder and ensure the old and new clients don't run simultaneously.
Interested in helping? Contributions to finalize E2EE support are welcome!
This module includes a node to register users using the Synapse secret registration endpoint. It returns both an access_token and a device_id`, perfect for setting up the bot.
