How to retrieve images from WROVER esp32 camera

ESPHome
#1

Hi

Firstly - this is my first post so apologies if I break any rules - just let me know and I’ll fix up

I have ESPHOME with Home Assistant that is running Supervisor mode on a Raspberry Pi4. I have recently configured up a Freenove ESP32-WROVER-DEV which has an “inbuilt” camera. Everything appears to be working fine and the camera appears to be taking shots every 10seconds - my question is how do I recover these shots in HA?

Here’s the log output and YAML if this helps at all

Any help would be greatly appreciated - thanks

By adding the camera entity to a home assistant dashboard page.

#3

Thanks for your quick reply - no sooner than I had read your reply than I noticed HA had added it to the dfeault dashboard all on it’s own. The only change I made just beforehand was to remove a blank space from the camera name - I suspect this made the difference

Anyhow - thanks for your reply

Did you have any other configuration related to the camera? Your log shows that there are some camera parameters (contrast etc.), but I suppose those could be visible on my log too if the camera setup succeeded. I have a similar board (not Freenove branded though) and I cannot get the camera working. ESPHOME camera - Setup Failed: ESP_ERR_NOT_FOUND - #4 by rantaki3

I start to think that I should just order another, this time Freenove board, as it seems to work for you.

#5

Yes but you don’t even follow advice.

#6

I suppose you cannot answer on behalf of ian.c.bell? I asked the question for confirming that there was nothing more to get it working i.e. the example worked for his board as it is. If so, then I will get the same board - actually ordered it already.
