ESP Home and ESP32 S3 Box?

ESPHome

Hi Everyone :slight_smile:
I am wondering, if ANYONE has tried this small device with ESPHome?

It is called ESP32-S3- Box, and is developed by Espressif - and comes with a built in “Voice-Controll”
The Voicecontrol itself is limited to “Hi ESP”… but it seems to have a built in Microphone and I question myself, if it would be possible to use the device with ESPHome… ?

I think, that would be a cool Hardware to create satelites for the Assist ?“year of voice”? :wink:
Maybe - there are some ESP experts who have already tried to use this device, or maybe, this might be of interest for the NabuCasa Team to see, if it would be possible to integrate into ESPHome / HomeAssistant?

→ Use VoiceControl for HomeAssistant
→ Get Data from HomeAssistant and display it on the Screen

I would start to experiment with this - but at the moment, I’ve just started with some small esp projects, and therefore, I think I don’t have the experience to work with such a device at the moment :slight_smile:

Thanks, good tip. I have not seen this one before.

Nice find!

Here’s the repo for that project:

Ha thanks :slight_smile:
That’s what I’m looking for - especially after the may Release :slight_smile: yay!! Just need to find the time to dig into this

That project is not using ESPHome so not sure how compatible it will be with the features in the May Home Assistant release

7

Also have a look at GitHub - toverainc/willow: Open source, local, and self-hosted Amazon Echo/Google Home competitive Voice Assistant alternative (which is also not ESPHome).

I am pretty new to ESP (have been using esphome, so easy…)

I ordered a s3box too - and as esp-idf 5.0 supports s3 devices - why cant we use it in esphome? I guess it is the screen part? Im not even sure how the screen is connected (which pins). I cant wait to get it :slight_smile:

So, just received my ESP32-S3-Box…
Since my primary usage is (as of now) Bluetooth-Proxy (family acceptance factor for this box is better than for any ESP32 Dev-Board) … I am running a very basic ESPHome Config.

So far - working as expected:

esphome:
  name: esp32box
  friendly_name: ESP32Box

  - platform: wifi_signal
    name: "WiFi Signal Sensor"
    update_interval: 60s

  - platform: wifi_signal # Reports the WiFi signal strength/RSSI in dB
    name: "WiFi Signal dB"

    entity_category: "diagnostic"

# Example configuration entry
  - platform: internal_temperature
    name: "Internal Temperature"
    entity_category: "diagnostic"

captive_portal:

Next steps would be to enable the Display - and showing some Information provided by HomeAssistant…
Also, I need to see, if I need to change the ESP-Framework for example to ESP-IDF, as mentioned in the ESPHome Documentation:

ESP-IDF framework

This is an alternative base framework for ESP32 chips, and recommended for variants of the ESP32 like ESP32S2, ESP32S3, ESP32C3 and single-core ESP32 chips.

Example configuration entry

esp32:
  board: esp32-c3-devkitm-1
  framework:
    type: esp-idf
    version: recommended
    # Custom sdkconfig options
    sdkconfig_options:
      CONFIG_COMPILER_OPTIMIZATION_SIZE: y
    # Advanced tweaking options
    advanced:
      ignore_efuse_mac_crc: false

Any progress? My “Lite” just showed up over the weekend and i’m looking forward to getting in there and start experimenting with ESP-Home on it.

Not yet.
Haven’t the time to do more experimental Work on this…
Still Just working as simple Bluetooth proxy

I’ve made some progress on this after looking at the pinouts. The one thing that isn’t working yet is the display. I think I got the mic and speaker right but have not tested those yet.

I referred to this for the pinout btw: arduino-esp32/pins_arduino.h at 3ec5f4efa1de4342aaab742008dc630091e5e035 · espressif/arduino-esp32 · GitHub

Hi :slight_smile: Thanks for your reply :slight_smile:
Whenever I activate the code for the Display, all other sensors went unavailable…

I will also see if I can get this working somehow… + some additional options (mute switch), voice command-buttons (as described in ESPhome → Push to talk)

Another thing I would like to add is an option to switch off the PowerLED… :smiley: :wink:

15

Found something in the ESPHome FeatureRequest Tracker:

16

Any idea where i can order the box in europe, Belgium to be percise.

I tried on adafruit, but shipment is almost the price of the box itself…

17

I got mine from Amazon… Not cheap, but no shipping costs …

18

Care to share the link?

I can only find the lite version on amazon.de

19

I’ve checked… “Currently Not available”

But here’s the link:
