hi Markus.
Great work.
I tried to copy/past the configuration.
I received the following error message: couldn't find ID 'clock_brightness'.
How and where can I define the ID?
Kind regards

@KuePe yes it was missing from the example. It's a global variable I used to limit the brightness of the clock, but you can also do that by using the color_correct: [50%, 50%, 50%] line.

I have updated the gist to include "Hour indicators" as well.

Hello Thomas

Thank you very much.
Unfortunately, I received another error message:

src/main.cpp: In lambda function:
src/main.cpp:727:34: error: 'indicator_color' was not declared in this scope
clock_ring_colors[i] = indicator_color;

@KuePe I hope it is fixed now. Sorry about that but its kinda hard to c&p only the necessary parts without leaving out important stuff 😄

Which version of esphome did you use ? I have multiple errors with your code with current version of ESPHome :(

Added some functionality and please note you must define a time source, which isn't defined in the original.

May I suggest to use the homeassistant sntp source ? easier 👍

The latest, version 1.14.3

Absolutely! I only used SNTP because it did not want to require Home Assistant and I wanted the clock to at least be able to get the time without needing Home Assistant. Really just a operational choice I made. :)

Sorry for late answer, just coming back on this and still unable to compile properly your example :(

The variable it is defined by ESPHome when using an addressable lambda effect, see here. You cannot just use lambda, you have to use addressable_lambda.

If this is not working it is an error in ESPHome, or they changed it and the docs are not up to date.

Working for 24 LEDs or 60 LEDs. The hour hand moves gradually, not in steps

update: added binary sensor status

Thanks for the share with a code that is working ;) Flashed my system here and works perfect (y)

Hello,

I have a strange problem. I live in the Europe/Brussels timezone, I added this to the time: component, when I check the time in the esphome log of this device it displays the correct time, but on the clock display it show the time +1 hour.

Anyone who has also this 'problem'? (I can change this by selecting the Europe/Belfast timezone, but it is a strange thing to do)

Regards
Dirk

This is really cool, just finished implementing it! Made me order a 60 Led ring for this!

Added some functionality and please note you must define a time source, which isn't defined in the original.

big YAML chunk...

I was looking for a code with the ESP32, thank you for your sharing, however, when I load the program, I can no longer use the OTA, in the clear the wifi does not work. I have tried loading other programs and have no problem with the wifi. Do you know what can cause this in your code? thanks

EDIT: removed big yaml c&p for better readability

Interested in adding an offset, as I've a picture frame that could make a nice clock, but the first LED is at the bottom left. Rather than being a ring, it's a rectangular frame with 144 LEDs ...

Any ideas on an easy way to do this? Thanks

Very nice! Working fine with latest ESPHome version 2021.12.3.

@markusressel would you mind adding a license to the code? I have a 3d printed case and dedicated PCB which I'd like to put into a repository at some point. It would be great if the code setup based on this version could be added too.

@t-paul Thx for asking, looks great!

Not sure how I can add a license to a gist, but you can consider it CC0.
Attribution would be appreciated, but is not required.

Feel free to post a link to your repository here. If it gets more traction I would love to see this become the new place for maintaining and improving this gist.

@markusressel cool, thanks! I suppose the comment is already enough.

If you want to make it more obvious, you could add some comment lines at the beginning or end of the yaml file (I think this uses # as comment character) similar to what we did with our advent calendar scripts.

When compiling this example, I get al lot of warnings of ESPColor being deprecated, like:
warning: 'using ESPColor = struct esphome::Color' is deprecated: esphome::light::ESPColor is deprecated, use esphome::Color instead.
Have no idea how to edit the code to repair this. Anyone any clue how to do this? Appreciated!

@rocob @markusressel Small correction: last line should divide bij 24 else the hour-hand moves 10 leds instead of 5 per hour

           int hour_inc_min_idx = hour_idx + (int) (((float) time.minute / 24) * (it.size() / 60));

The code line you reference and the text you write don't match up.
The hour_inc_min_idx is used to advance the "hour indicator" by tiny amounts, even if not a full hour has passed.
Dividing by 24 wouldn't make sense on an analog, 12 hour clock.
Not sure what you want to achieve there.
