If you have a Levoit Core 400s air purifier, you can flash it with ESPHome.

The guide says: To get to the microcontroller, it's necessary to open it from the bottom.
It's actually easier if you don't care too much about its aesthetics.

There is a gray ring at the top and black latches on the inside behind the gray ring. You can push these latches in by using 2 sharp & thin knives.

One knife to lift the ring and a second one to push in the latches. Parts of these latches will break! But don't worry, it will reassemble just fine.

If you take the bottom-up path, you will have to extend the internal cables. Otherwise, you won't be able to reconnect the PCB to the unit.

Please know, you will have to take the bottom-up path halfway, otherwise you cannot see the inside latches. You have to detach the upper part from the lower part.

What a dumb design choice by #Levoit!

Great job on this, @tuct.

Argh.
I know why I had problems in the beginning.
on_boot will execute *after* all the display init stuff.
But I need power before that happens.

Now with temperatures!

I'm especially happy with the "Ubuntu" font, 10x better than Roboto imho

Yeaaaa. #esphome on a CrowPanel!

Hopes to get #esphome to run on my #crowpanel display crushed.
Shit doesn't work, even when I use the compatible WeAct-2.9in-3c model (SSD1680).
Fuck this shit. I don't have the patience for this!

Kiddo is taking a class wherein they learn how to program in a visual block language that spits out #Arduino flavored c++. They load it onto their Arduino nano and then, eg, make a rainbow on some RGB LEDs.

I had the distinct privilege tonight of walking kiddo through the #esphome config that controls the LED annunciator in our kitchen and watching them draw parallels to their code from class. They even started talking, unprompted, about how they debugged their program in class.

I am extremely proud of my little nerd.

I have a big problem getting #esphome to run on this CrowPanel display - https://www.elecrow.com/wiki/CrowPanel_ESP32_E-paper_2.9-inch_HMI_Display.html - which is basically a esp32-s3-devkitc1-n8r8.

The device connects to my WiFi, but the log (esphome run...) stays completely empty.
What am I missing?

https://privatebin.net/?17c48ccb5da120ce#7XVtHsjPDtmTXXoeMqkVDFMbdqAnw8sRbwUxU2wJvAD1

edit:
esphome logs over wifi/OTA work, so the board makes a connection.

edit2:
After reading the schematics, I set hardware_uart to UART0 - stilll no luck.

edit3:
all I see with screen is
ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x1 (POWERON),boot:0x2b (SPI_FAST_FLASH_BOOT)

after that, silence.

Does anyone use #Shelly 2PM Gen3/Gen4 as Bluetooth Proxy for #HomeAssistant?
Any difference between G3 and G4 that would justify buying the G4 (18€ vs 27€).
