TRMNL serves as a digital display for TRMNL e-ink devices and BYOS installations. It can function both as a mirror for existing TRMNL devices or as a standalone TRMNL display connected directly to a Bring-Your-Own-Server (BYOS).

> ⚠️ Note: TRMNL app currently requires device API key for non-BYOS based devices. TRMNL device must have a developer edition or BYOD license to enable device API key.

Key Features:
• API Token-based authentication with TRMNL/BYOS API
• Automatic periodic image refresh from the server
• Adaptive refresh rate based on server response config
• Manual refresh capabilities and option to load next playlist image
• Support for custom server URLs for BYOS installations
• Refresh history logging for tracking & validation
• Support for standard TRMNL, BYOD (Bring-Your-Own-Device), and BYOS (Bring-Your-Own-Server) configurations

The app requires a valid access token or device MAC address to connect to TRMNL services. You can obtain this through:
• Owning a TRMNL device with the developer edition add-on
• Purchasing the BYOD product
• Having a self-serve installation of TRMNL service using BYOS

Perfect for:
✓ TRMNL device owners who want a mobile companion display
✓ Developers testing TRMNL integrations
✓ BYOD (Bring Your Own Device) users
✓ BYOS (Bring Your Own Server) installations
✓ Anyone with e-ink tablets looking for a smart display solution using TRMNL services
