Did anyone already trying to get ESPHome to work on LilyGo T-Embed

nickrout · January 10, 2023, 11:41pm

The code above looks complete without any additional libraries.

rudimarp · January 11, 2023, 12:43am

Thanks for the code @lukasz-tuz, it’s working like a charm (the display).
I got almost everything working now, except for the LEDs because of the GPIO PINs used on the ESP32-S3 are not accepted by FastLED 3.3.2 code. Looks like version 3.5.0 has corrected the PINs mapping but I’m having a hard time using/changing to the newest version on ESPHome

lukasz-tuz · January 14, 2023, 12:41pm

Ah, yes, the FastLED issue. When trying to enable the st7789 I learned about the external_components feature of ESPHome. That did not really help with the display, but creates an easy way to fix the LEDs.

In your project directory, create esphome/components/fastled_base and esphome/components/fastled_spi directories.
Copy ESPHome core component code (all files), e.g. from here (fastled_base), and here (fastled_spi)
In your local version of fastled_base open __init__.py and simply bump the FastLED code:

    await light.register_light(var, config)
    cg.add_library("fastled/FastLED", "3.5.0")
    return var

In your YAML file configure directory with external components:

external_components:
  - source:
      type: local
      path: esphome/components

Configure LEDs as usual:

light:
  - platform: fastled_spi
    chipset: APA102
    data_pin: GPIO42
    clock_pin: GPIO45
    rgb_order: BGR
    num_leds: 7
    name: "T-Embed LED Ring"
    effects:
      - addressable_rainbow:
      - addressable_scan:

When building, ESPHome will use local fastled_spi definition, and will download 3.5.0 version of FastLED. For T-Embed, with ESP32S3, this is completely fine; seems that ESPHome keeps the version downgraded due to some issues coming up on ESP8266.

BTW, T-Embed makes for a great smart home remote Some time ago I tried building my own version of such device, with OLED display and NeoPixel LED ring. It actually worked for a while, but there were stability issues on account of my poor soldering skills.

However, I was able to move ESPHome YAML from that device to T-Embed with very little changes (mostly related to different display controller), and now it works like a charm Now I’m trying to get esphome-lvgl working, hoping to make a component that implements ESPHome’s Display Menu integration using fancy lvgl widgets.

EDIT: I just clicked the esphome-remote link. Oh well, looks like the home remote thing has already been done, and much better than my attempts at that Thanks for the link @lmatter!

rudimarp · January 14, 2023, 7:09pm

Thanks @lukasz-tuz, this was a big help.
I’m used to external_components, and I have serveral customizations from original ESPHome components, but somehow, I’ve missed that version configuration on fastled_base.

I’m glad your project is working, and now I’m trying to decide what type of I2C sensor I want to use with this device (maybe SCD41) and a way to increase the size of the original 3D Printed case to fit the sensor.
Thanks again.

lmatter · January 14, 2023, 8:45pm

You’re welcome! I hope that by standing on the shoulders of you giants I can get a cool remote working. Sadly the T-Embed only has one button. I might have to add another to it somewhere.

lmatter · January 15, 2023, 12:43am

Sorry if this is boneheaded, but how do you get this installed on the T-embed? I took the config from @lukasz-tuz, manually built it (modern format) and installed via web.esphome.io but the logs say:

ESP-ROM:esp32s3-20210327
ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x7 (TG0WDT_SYS_RST),boot:0xb (SPI_FAST_FLASH_BOOT)
Saved PC:0x40043ac8
Invalid chip id. Expected 9 read 3460. Bootloader for wrong chip?
ets_main.c 329 
Terminal disconnected: NetworkError: The device has been lost.

What type of ESP should I select when I create a new entry in my local esphome manager? I tried Generic ~~ESP32-WROVER~~ [EDIT: I realized WROVER was wrong and switched to Espressif ESP32 Dev Module - still didn’t work]
Thanks!

nickrout · January 15, 2023, 3:12am

In esphome click install|plug into (there is choice of whether the device is pugged into the computer you are running the browser on, or the machine running esphome)

lmatter · January 15, 2023, 8:19pm

They are the same machine (I don’t run esphome on HA, I run it on my laptop in docker). I’m asking about this step:

nickrout · January 15, 2023, 8:38pm

Sorry, its shown here Did anyone already trying to get ESPHome to work on LilyGo T-Embed - #19 by lukasz-tuz

platformio_options:
  board_build.mcu: esp32s3
  board_build.name: "LilyGO T-Embed ESP32-S3"
  board_build.upload.flash_size: "16MB"
  board_build.upload.maximum_size: 16777216
  board_build.vendor: "LilyGO"

Choose any one and edit it if need be.

lmatter · January 15, 2023, 8:47pm

Thanks. I must be doing something wrong then because I don’t have esp32s3 as an option. I pulled the latest version of the container - maybe I need a dev version?
[EDIT: I think the issue I’m having is that I’m running esphome:latest. I just found a container called esphome:dev. I’ll try that one]

lmatter · January 15, 2023, 9:15pm

ok, running esphome-dev gives me the ESP32-S3 choice. But now I’m getting a new issue, which is the editor (and compiler) not recognizing the platformio-options component: I must be still missing something.

nickrout · January 15, 2023, 9:25pm

According to the docs, the platformio_options should be indented right

(Although this is contrary to @lukasz-tuz 's post)

lmatter · January 15, 2023, 9:47pm

That was it! Thanks! I owe the Internet 1 rtfm.

    board_build.vendor: "LilyGO"
 
  on_boot:
  # Send the `SLPOUT` command as early as possible
    priority: 800
    then:
      - lambda: |-
          id(disp).enable();
          id(disp).transfer_byte(0x11);
          id(disp).disable();

      - switch.turn_on: power_on

nickrout · January 15, 2023, 9:49pm

Lol, we are all in that debt.

lmatter · January 15, 2023, 9:59pm

So I’ve had some small success here. I was able to install the firmware using web.esphome.io and it was discovered by my HA instance. I’ve seen before where an esphome device won’t “work” until I add it into home assistant (i.e., hanging on the “api” step?) so I did that. I can get logs via wireless:

[21:52:33][C][st7789v:129]:   B/L Pin: GPIO15
[21:52:33][C][ota:093]: Over-The-Air Updates:

[21:52:43][D][esp32.preferences:142]: Saving 1 preferences to flash: 0 cached, 1 written, 0 failed

But the display was off and the rotary does nothing [other than log]. I went into the device configuration in HA and when I turned the power on and the display backlight on, it started to display the time (wrong timezone though) but that’s it. It’s a cool looking clock at this point.

I have not performed the steps in the “Fast LED issue” comment, perhaps I will try that next.
Is this the expected outcome?

[EDIT - I read the code - that’s exactly what it’s supposed to do. ] Next I will try to get esphome_remote working on it. Thanks for the huge boost here!

lmatter · January 16, 2023, 11:52pm

Woot! I have it working with esphome-remote. Still some kinks to work out but I was able to control my HomeAssistant with it. Support for Lilygo T-Embed device. WIP by lmatter · Pull Request #39 · landonr/esphome-remote · GitHub

Aw, crap, I did not notice that indentation got messed up Sorry about that and thanks for pointing that out. Original post edited, so - hopefully - no more mess-ups there

uz_blvk · May 29, 2024, 2:43pm

I’ve been in the discord trying to figure out loading in a newer FastLED version without having to create a custom component and one of the devs, cebejla, was able to get it working (documentation may need some updates) with the below

  libraries:
    - FastLED=https://github.com/FastLED/FastLED.git#3.7.0

ion · July 11, 2024, 1:17pm

I have succeeded to make T-Embed work with Esphome, except the microphone. It seems to use an ES7210 chipset which is not supported by Esphome.
I also tried the es7210 component from here:

But it doesn’t work, this component it requires also i2c, but the T-Embed has no i2c for ES7210, only I2S.
So the es7210 component from rpatel fails because it cannot detect any device on the specified i2c address.

I also looked at the Lilygo repo here:

I was thinking that I could port some code from there.
But after a few hours I realised I have no chance :))

Did anyone succeed in making ES7210 from T-Embed work in Esphome?

styphonthal · July 11, 2024, 1:41pm

Could you post the code you are using now? Do you have the speaker working?
