+# Home Assistant ePaper Remote - Project Memory
+
+## Future Entity Types to Add
+
+High value additions:
+- **Climate/Thermostat** - Temperature setpoint slider, very common use case
+- **Scene** - One-tap button to activate (no state feedback needed)
+- **Script** - Run automation scripts (same as scene)
+- **Lock** - Lock/unlock doors (button with state)
+- **Media player** - Volume slider, play/pause button
+
+Lower priority:
+- **Input number** - Generic slider for HA helpers
+- **Input boolean** - Generic toggle (functionally same as switch)
+- **Vacuum** - Start/stop/dock commands
+
+## Key Implementation Details
+
+- Firmware slider bar is always 100px (BUTTON_SIZE constant) - not configurable
+- SLIDER_HEIGHT = 170 in configurator (100px bar + 70px label space)
+- Label drawn at widget top, bar drawn at widget bottom
+- Configurator uses File System Access API for direct project writes
+- Icons generated from MDI SVGs, converted to 1-bit BMP in JavaScript
