ESP32-CAM works on Web Server, but not in HA

ESPHome
1

Hi All,

I have been following this guide for the past few days trying to get this ESP32-CAM (MB, with attached usb connector) working with Home Assistant:

Sorry, I can’t put more than 2 links in a post.

I compiled the arduino code, connected to the temporary AP made by the esp32, and was able to take still images (confirming the camera is working).

I then added the device to ESPHome and installed the following code on top of the standard ESP32 ESPHome code:

I use OTA to push the code and it completes successfully, but does give one small error line inside the logs:

At this point I am able to see the device on my router management page, the device shows as online in ESPHome, and I have 2 entities added (camera and camera light). Adding the camera entity to a Picture Entity card just shows the status as “Idle” and no picture:

BUT, the device must be talking with HA and ESPHome because I am able to toggle the camera light on and off.

What am I doing wrong here? Any suggestions? My ultimate goal is to have an ESP32-cam integrated into HA such that I can setup automations to take a snapshot once a day (time lapse of indoor garden plants).

well for a start you are posting screenshots of text files. Please please copy and paste!

Here’s the code used:

esphome:
  name: esp-cam-4

esp32:
  board: esp32cam
  framework:
    type: arduino

# Enable logging
logger:

# Enable Home Assistant API
api:

ota:
  password: ""

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Esp-Cam-4 Fallback Hotspot"
    password: ""

captive_portal:

# Example configuration entry

  pixel_clock_pin: GPIO21
  reset_pin: GPIO15

  # Image settings

output:
  - platform: gpio
    pin: GPIO4
    id: gpio_4

light: 
  - platform: binary
    output: gpio_4
    name: esp32-cam-4 light

And here’s the logs once the device connects to ESPHome dashboard:
