Yes, both the Puppet and Lovelace Kindle Screensavers images load in a web browser. I have even downloaded one of the images and used the image (not online image) component to load the file manually which works. So the issue seems to be with accessing or processing the image, not displaying it.
I would love to use this setup, I configured everything the same but in the log it tells me:

Why doesn’t it work?
Got it to work! I switched to bmp. Now it all works. Which is weird because I would say bmp is bigger than png…
Just add &format=bmp to your url and change format: BMP

Created an account to say thank you for mentioning the bmp solution. I was getting frustrated and now it just works. On to making a ridiculously awesome dashboard!

Sorry for the newb question, but I just got my TRMNL OG kit. I was able to use the guide on the Wiki and I can get the HA dashboard to work while I am at home. Does anyone know how I can get it to work if I want put this at my desk at work (different network than my house)? I’m looking to use a dashboard to have weather/forecast, time/date, state of some sensors that I can monitor while I am at work. TIA.
Are you able to use HA from work (is it exposed to the internet)? If so, it’s just a URL and WIFI change. If not, that’s a much bigger task than this thread can support.
Easiest path is to get a Home Assistant Cloud subscription, but you can also do it yourself with some work.
Sorry I was not clear. I have duckdns set up for me to access my HA via web browser from any computer (and yes, I am able to access it from work). But for the ESP32 board, what code do I change to access the duckdns URL? Can you use your YAML code from your original post to show me where I can use the duckdns URL? Thanks.
You’ll need to open up port 10000 (or whatever port you have set in Puppet) to access Puppet, but I’d be careful doing that. Puppet is currently wide open with no security.
Then you should be able to change the “url:” below
http://192.168.1.101:10000/dashboard-robin/display
online_image:
- id: dashboard_image
format: PNG
type: BINARY
buffer_size: 30000
url: http://192.168.1.101:10000/dashboard-robin/display?viewport=800x480&eink=2&invert #change this link to your screenshot link
update_interval: 20s
on_download_finished:
- delay: 0ms
- component.update: main_display
Is there a way to do this without using Puppet? For instance, right now I am using a simple temperature forecast and time display. I am making calls to entity_id, for example:
text_sensor:
-platform: homeassistant
entity_id: weather.home
id: myWeather
display:
- platform: waveshare_epaper
id: epaper_display
model: 7.50inv2
cs_pin: GPIO44
dc_pin: GPIO10
reset_pin: GPIO38
busy_pin:
number: GPIO4
inverted: true
update_interval: never
lambda: |-
// 1. Display the title "Weather"
it.printf(left_center_x, 110, id(mid_font),
TextAlign::TOP_CENTER, "Weather");
// 2. Get the weather condition and select the corresponding icon
std::string weather_condition = id(myWeather).state;
std::string weather_icon = "\U000F0599"; // Default icon
(sunny), as a fallback for unknown states
if (weather_condition == "partlycloudy") {
weather_icon = "\U000F0595"; // weather-partly-cloudy
} else if (weather_condition == "cloudy") {
weather_icon = "\U000F0F2F"; // weather-cloudy
} else if (weather_condition == "rainy") {
weather_icon = "\U000F0597"; // weather-rainy
} else if (weather_condition == "snowy") {
weather_icon = "\U000F0598"; // weather-snowy
} else if (weather_condition == "windy") {
weather_icon = "\U000F059B"; // weather-windy
} else if (weather_condition == "fog") {
weather_icon = "\U000F0594"; // weather-fog
} else if (weather_condition == "lightning") {
weather_icon = "\U000F0596"; // weather-lightning
}
// Display the weather icon
it.printf(left_center_x, 240, id(weather_icon_font),
TextAlign::CENTER, "%s", weather_icon.c_str());

I didn’t go down that path, so I can’t answer that. It was way too tedious to try to create a decent dashboard using just the ESP YAML.
Maybe someone else can answer?
I got a reTerminal E1002 Color eink display and redid some of my dashboard (I’ll post it in a new thread). I ported some of those changes to the XIAO 7.5" BW and also changed it so that it goes to sleep after the refreshing the display (waits 30 seconds). Below is the new YAML for both.

Hey all! I just got the reTerminal e1001 and got it displaying a dashboard from Puppet. I’d like to hook up the green refresh button to be able to pull a fresh dashboard on demand. Anyone try something like this yet?
Take a look at my thread for the E1002.
I have the green button mapped to wake up the device which causes a refresh and it goes back to sleep. There’s also commented out code for mapping the button to do something else.

I also bought the ePaper Panel.. but am looking to do some other integration…
I’ve worked with other esp32 boards and other TFT displays and other ePaper displays… but I’m stumped…
I tried to use the examples Seeed_GFX-master library… at the top of the Bitmap_07inch50 example I have tried many combinations of: #include “TFT_eSPI.h”
#include “my_progmem_unsigned_char.h”
#include <../my_setups/Setup17_ePaper.h>
#define BOARD_SCREEN_COMBO 502 // 7.5 inch monochrome ePaper Screen （UC8179）
#define USE_XIAO_EPAPER_DRIVER_BOARD
#if defined(USE_XIAO_EPAPER_DRIVER_BOARD)
#define TFT_SCLK D8
#define TFT_MISO D9
#define TFT_MOSI D10
#define TFT_CS D1
#define TFT_DC D3
#define TFT_BUSY D2
#define TFT_RST D0
#endif
I can upload a sketch to the board. When I upload the examples>Test and diagnostics>Read_User_Setup the serial montior reports: Display SPI frequency = 40.00
[/code]
[code]
TFT_eSPI ver = 2.5.43
Processor = ESP32

but the Serial.println ( or Serial.print ) does not work in the ePaper examples and the ePaper does not respond ( not even to HelloWorld ) . Do I have a user_setup.h problem ? Maybe a stale setup from another project ? Sorry this is bit off topic.. but same product… Thanks in advance.
Hi there and Welcome here…
So checkout a thread i have on here for a smaller 4.3 panel Set the config correctly , those setting won’t work, edit the user setup select file.
you want e-paper selected, not the LCD driver 9341.
