Key Technical Insights

Architecture Philosophy

Tasmota follows a modular architecture where:

• Core firmware provides basic functionality (WiFi, MQTT, web interface)
• Features are conditionally compiled based on #define directives
• GPIO mapping is completely flexible through templates
• All functionality is controllable via commands (MQTT, HTTP, serial, web console)

Memory Management

• ESP8266: 80KB RAM total, ~25-30KB available for applications
• ESP32: Much more generous memory, supports advanced features
• Code size optimization is critical for ESP8266 OTA updates
• Flash memory partitioned for dual-boot OTA capability

Communication Protocols

1. MQTT (Primary): All device control and telemetry
2. HTTP: Web interface and REST API
3. Serial: Direct console access
4. WebSocket: Real-time web interface updates

Extensibility Mechanisms

1. Rules: Event-driven automation (up to 1536 characters)
2. Berry Scripts: Full programming language (ESP32 only)
3. Scripting: Legacy scripting system (ESP8266)
4. Templates: Device configuration sharing
5. Custom Drivers: C++ sensor/peripheral drivers
