My device is running out of memory. How can I optimize?

If you encounter memory issues:

1. Reduce log verbosity in production builds:

   CONFIG_LOG_DEFAULT_LEVEL_WARN=y

2. Enable PSRAM if your chip supports it:

   CONFIG_SPIRAM_SUPPORT=y

3. Disable unused features: Turn off unnecessary RainMaker features:

   /* Don't enable features you don't need */
   /* esp_rmaker_schedule_enable();
    * esp_rmaker_scenes_enable(); */

4. Monitor memory usage:

   ESP_LOGI(TAG, "Free heap: %d", esp_get_free_heap_size());

   Or use the mem-dump serial console command when the console is enabled:

   >> mem-dump
   
   	Description	Internal	SPIRAM
   Current Free Memory	136572		0
   Largest Free Block	114688		0
   Min. Ever Free Size	110896		0

For comprehensive memory optimization (static RAM, heap, lwIP, Wi-Fi buffers, Mbed TLS, PSRAM, IRAM), see the ESP-IDF Minimizing RAM Usage guide. Use idf.py size and idf.py size-components to analyze memory, and esp_get_free_heap_size() / esp_get_minimum_free_heap_size() for runtime heap monitoring.
