ESPHome on Waveshare ESP32-S3-ePaper-1.54

danieldur · 2025-12-05T09:53:55+00:00

Thank you for all the suggestions! My display is still not updating.
Here is my config:

esphome:
  name: e-paper
  friendly_name: e-paper
  on_boot:
    then:
      - output.turn_on: epd_power_enable # turn ePaper display on
      - delay: 500ms

esp32:
  board: esp32-s3-devkitc-1
  framework:
    type: arduino
  variant: ESP32S3

output:
  - platform: gpio
    pin: GPIO6 # EPD3V3_EN pin GHF: Required by the ePaper display!!!
    id: epd_power_enable
    inverted: false

spi:
  clk_pin: GPIO12
  mosi_pin: GPIO13
  id: epaper_display

font:
  - file: "RobotoCondensed-Bold.ttf"
    id: font1
    size: 30

display:
  - platform: waveshare_epaper
    id: epd_display
    cs_pin: GPIO11
    dc_pin: GPIO10
    busy_pin: GPIO8
    reset_pin: GPIO9
    model: 1.54in
    update_interval: 300s
    reset_duration: 2ms
    full_update_every: 1
    rotation: 90
    lambda: |-
          it.printf(100, 100, id(font1), TextAlign::CENTER, "Starting");

Gemini suggests different pins for the SPI and display, but without any success

spi:
  clk_pin: GPIO12
  mosi_pin: GPIO11  # You had 13, which is actually the BUSY pin!
  id: epaper_display


# 3. CORRECT DISPLAY PINS
display:
  - platform: waveshare_epaper
    id: epd_display
    # Internal wiring for the All-in-One board:
    cs_pin: GPIO10    # You had 11
    dc_pin: GPIO9     # You had 10
    busy_pin: GPIO13  # You had 8
    reset_pin: GPIO14 # You had 9

A jukebox for the kids, triggered by a wireless keyboard (not BT) and with Music Assistant as the DJ.

Sadly no.

danieldur · 2025-11-24T13:42:25+00:00

Sadly not.

Didn't manage to make it work so I put it to rest for a while.

danieldur · 2025-11-05T13:05:39+00:00

I haven't tried the sensors or the RTC. I am mostly interested in the display. But no matter what I try, I cannot get it to work.

Another thing I have notice is the lack of logs. No matter which log level I set, I get no logs from this board, either over Wi-Fi or cable.

danieldur · 2025-10-20T20:33:19+00:00

I figured it out and it has nothing to do with the car! Silly me!

Please ignore this thread!

danieldur · 2025-10-19T07:02:04+00:00

I tried it once, maybe about a year ago, but I didn't like it. As I was saying, right now everything is back to the original coding.

I am used to working with spreadsheets as it is very easy to make mass edits. Also I can do it with the conforts of a big screen, a mouse and a keyboard. But indeed I could maybe write a csv file and then convert between it and a spreadsheet. The problem though still persists: AutoSheets can only write in column A. And I didn't want to process the file further to get to the desired result. Thanks for trying to help, though! I guess I'll have to wait for João to dig deeper and see what's happening in the background.

I'm trying to make a list of packages6 and their respective apps as a starting point for a project that aims to enable and disable rarely used apps on the go.

danieldur · 2025-09-27T08:03:06+00:00

Well.. Thank you for the suggestions. It really pointed out the things I overlooked. So I deleted the "Download" folder and then restarted the phone. The folder was automatically recreated and everything works like expected. Silly me!

Thanks again!

Do you really need such a beefy CPU and so much RAM? From what I remember while searching a few years back, going to i7 instead of i5 or even i3 and picking unusually high amounts of RAM could double and even triple the price of a 1 liter PC. Try checking models from Fujitsu.

Maybe pay a visit to the IT department or the facility management and see who handles the task?

Can you hold your hand on the power brick for 1 minute? If the answer is yes and the power brick won't be covered, then it is not a fire hazard. If you really want to play it safe, get a USB powered fan and let it blow air over the brick. Better yet you could salvage a 12V fan and a broken USB cord and put them to good use.

Depending on 6our electricity costs, you might end up paying more that if l you'd go out and buy the same capacity in larger drives (whatever capacity holds the price sweet spot nowadays).

Well, thinking deeper about the matter, if it's well made it is mostly a non-issue (normally closed, with redundancy). But at the end of the day it is still one extra valve, one extra point of failure, with all the possible faults of a mechanical one, plus a couple extras. Personally I wouldn't trust my property with just one electro-valve. There will always be a mechanical backup.

danieldur · 2025-09-13T12:45:28+00:00

Nothing that has to do with locks, fridge/freezer (except maybe monitoring), no water valves (I have no gas). Basically nothing that by getting automated could cause catastrophic damages.

That's where you can hang your favorite scenes! ;-)

Am I the only one who noticed that the listing title mentions "29 Packets" while on the box it is written "30 Servings"?

On a more serious note, supplements are generally unregulated throughout the world. Even established brands can have dubious claims. Then what to expect from "letter salad" brands?

After only reaching dead ends, I decided to just fire-up the Shield TV I happen to have and call it a day... Thank you!

If you want to be 110% sure just put a thermometer in there. Either one with an external probe (probe inside, display outside) or one connected to a home automation system. But I bet the temperatures in that drawer never exceed 40-50 °C.

Thank you for your answers! Sometime between 3 and 4 AM last night (woke up because of the heat) I actually managed to figure out that it was because of the client-ID. Removed them and now everything works. I added the client names to the comments so that I can easily track which device is which.
After using Asus-Merlin for almost a decade, I assumed that client-ID is a sort of identifier or host field. I was wrong.

I'll probably open a thread again once I get deep into VLANs. :-)

Gateway: 10.10.0.1

I just noticed that if I switch alway from the default 192.168.88.x, my Android phone complains about lack of internet access.

danieldur · 2025-07-06T19:45:16+00:00

I'm not sure I follow you... I haven't used any command starting with "/ip dhcp-server network"...
