Hello Mike!
The DFR1154 (ESP32-S3 AI Camera Module) does not connect the camera's power-down pin to a programmable GPIO. For power saving, you can try:
1. Deep Sleep Mode: Use esp_sleep_enable_timer_wakeup() + esp_deep_sleep_start() to put the system to deep sleep (camera fully powered off; wake via timer/external interrupt).
Related example: https://wiki.dfrobot.com/dfr1154/docs/21371
2. Software Shutdown: Use esp_camera_deinit() to release resources (partial hardware power remains); reinitialize with esp_camera_init(&config) when needed.
niu.yixuan thank you for your response!
I would like to use the ESp32 device while the camera is off, so deep sleep is not an option. In terms of option 2, is there an ESPHome equivalent to turn off the camera at the software level?
