Couldn’t help myself, and instead of completing this project, I bought one of these to test…

Amoled screen… should look great.
Let us know!
Hi, i have some compilation probleme since a few days with lvgl.
esphome say me that the “btn” config must be rename into “button”.
and after that, i have no config error but compilation errors.
Have you any ideas ?
.piolibdeps/knob-salle-a-manger/lvgl/src/extra/widgets/animimg/lv_animimg.h:22:2: error: #error “lv_animimg: lv_img is required. Enable it in lv_conf.h (LV_USE_IMG 1)”
#error “lv_animimg: lv_img is required. Enable it in lv_conf.h (LV_USE_IMG 1)”

I’ve not done an update for a while, but I’d try a clean build files to see if it can force an update of all the backend/lvgl components
Have you received it yet? How does it compare to the M5Stack Dial in terms of screen?
Hard to get a great shot, but it’s sharper and better contrast. But it’s also noticeably smaller.
The dial is probably better overall, just an ugly orange and grey

Can you share your code. I love that background image
I’ve had much time to work on it unfortunately. The touchscreen is still not working, and I’ve not really had an opportunity to work on converting the driver into an esphome component (also, I am most definitely not a competent c++ coder).

Hello @mrgrlscz Steven,
I’m in testing mode of this device and starting with LGVL. Then I check your yaml files and I have questions about line using " <<: & and <<: * "
This is a kind of macro and if yes, where it’s start and where it’s finish ?
I don’t see any documentation in esphome where I saw this kind of usage.
Hi all, I am excited to read the progress you have all made collaborating and how active it is.
I am admittedly just trying to get my toes wet here, so I updated a couple samples that others have posted and
I keep getting the error “Unable to find action with the name ‘homeassistant.service’.”
I see the homeassistant.service in the yaml file but do not know what it specifically references or how to resolved this . Can somehow give a hint?
Hi, it’s called yaml anchors, not reserved for home assistant.
Here’s a (one of many) link to How it works

I wanted to share my progress with you, i started out with @mrgrlscz his work, but i wanted to use the M5Dial differently. My goal is to alter entities in Home Assistant, i also wanted to have a page per entity (more or less). Additionaly i want to use the rotary button to switch between pages, but also alter a widget on a page when needed. Below is a link to youtube where you can see it in action. It has got page breadcrumbs and an indicator that you have are in the scroll mode for the widget (single button click), instead of being in the scroll mode for the pages (double button click when in scroll mode for the widget).
There is a lot more to this one, so take a look. It’s not perfect, but its a start

Hey guys,
i created a housing for the M3 dial and would create more housings on your needs,
just tell me what you need and i will upload stl files.
There is also just the thead of the nut there:
and there are tools to fasten the nut.
Have fun,
best regards from germany
