ESP32-S2 DevkitM-1 V1.0

Hello,

I have ESP32-S2 from Espressif. When adding the device to ESPHome all works fine. It connects to WiFi after flash is complete. When I tried to add some functionality to it, for example sensors, switches or deep sleep I am getting the following error:

If anyone encountered this please if you are willing to share your experiences.

Thank you.

You’ll need to share your yaml.

Hello,
thank you for looking into it.

Here is the working log. As you can see it connects to WiFi and communicate with HA.

Here is working yaml file:

esphome:

esp32:
board: esp32-s2-saola-1
framework:
type: esp-idf

Enable logging

logger:

Enable Home Assistant API

api:

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

Enable fallback hotspot in case wifi connection fails

ap:
ssid: “Eso42S2 Fallback Hotspot”
password: “B3WITqOlb0ZG”

Here is same not working yaml. It is the same except switch sensor added. I have multiple ESP32 sensors where all this is working fine. The only difference for this yaml it uses esp-idf framework, others are using arduino.

esphome:
name: eso42s2

esp32:
board: esp32-s2-saola-1
framework:

logger:

ap:
ssid: “Eso42S2 Fallback Hotspot”
password: “B3WITqOlb0ZG”

switch:

platform: gpio
pin: GPIO18

I hope this will help solving the issue.

Thank you.

Hello I will try to follow your advice. Here is again.
Good working YAML file

  framework:

wifi:

  # Enable fallback hotspot in case wifi connection fails
  ap:
    ssid: "Esp32-S2 Fallback Hotspot"

And corresponding log:

Hello,

I got my esp32-S2 somehow working. I think the platform is still under development and some functions are not working. I just added esp-idf version to latest instead of default, everything else is the same.
Here is the yaml file which has switch, dht sensor and deep sleep component. Maybe someone will be found this useful.

esphome:
  name: esp32s2

esp32:
  board: esp32-s2-saola-1
  framework:
    type: esp-idf
    version: latest
    
# Enable logging
logger:

# Enable Home Assistant API
api:
  encryption:
    key: "IjddXe9udhMw7ewXU2YXZ0a5GxU1uG7+8MPBqvDDKgY="

ota:
  password: "b05870da12b050ef3d09d2e70a632315"

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

  # Enable fallback hotspot in case wifi connection fails
  ap:
    ssid: "Esp32S2 Fallback Hotspot"
    password: "3Mu3T0SIzrQ4"
switch:
  - platform: gpio
    pin: GPIO18
    name: "testsw"
sensor:
  - platform: dht
    pin: GPIO19
    temperature:
      name: "temp"
    humidity:
      name: "hum"
    update_interval: 15sec
    
deep_sleep:
  run_duration: 90sec
  sleep_duration: 30sec

Thanks,

I’m currently unable to link against Switch or Binary Sensor code, using esp-idf. Was this working briefly, and now broken?

esphome:
  name: book-button

esp32:
  board: esp32-s2-saola-1
  framework:
    type: esp-idf
    version: latest

# WiFi, etc snipped out.

switch:
  - platform: gpio
    name: "Book Button Light"
    pin: GPIO34
    id: display_light
    restore_mode: ALWAYS_OFF
