ESP32-CAM Capture

ESPHome
12

It might be a while, but I have a similar request. In my case, I made the esp32cam wake up every 10 minutes for 20 seconds. There’s an automation in HA that runs every 14 seconds and tries to download the picture.

Ideally, HA would know when to take the picture, I think it might be possible to do that. A better case would be if esp32cam can upload the file directly somewhere.

Battery consumption is somewhat decent, can be improved with longer sleep times - 150-240 mA while active, 3-5mA while sleeping. I’m keeping a backup of the old photo while getting the new one. Anyway, this is as far as I’ve gotten, for now.
