Hello all,
this question is so simple that I can’t find an answer searching the forum or the docs… 
So: when I add a button (or similar) to lovelace - there is a preselected icon like - let’s say - palette or as code: hass:palette
I figured out that there is something like hass:flash too but:
Where do I find the list of built-in icons?
Thanks, Bernd
Thank you @M1ke !
I knew, that with the answer I could write a much better question and get many answers 
Even in the docs / the additional resource at the bottom:
I think we’re using a later version than 5.3.45:
So:
Either way I just use:
and check the history on the rare occasion that an icon refuses to show up. 10 times out of 10 it’s because it’s a new icon that isn’t in HA yet and only takes a release or so until it is.
There’s also this:
Cool to have all the links and resources here in the thread!
If you search the docs for "icon" you won’t find that info… Perhaps there should be a link somewhere in variables-section for icon too?
Thanks for the additions!
5.3.45 was implemented in 0.113 and 5.5.55 will only be as of 0.115 - I am not sure whether 5.4.55 was introduced in 0.114 (couldn’t find anything related in the release notes) - can’t check, as I couldn’t wait for all the cool things in 0.115 
.
The release notes for each release (posted in the blog topic) usually list the MDI version if it is updated.
There’s also a place on the home assistant frontend github that shows the current version… but I cant find it.
Edit: Here it is. Search for @mdi:

Hy everybody!
I just create fork with some changes for ha users:
Check out here https://aatrubilin.github.io/pictogrammers.github.io/@mdi/font/5.9.55/
Man, that’s hella good, love the fact you changed the annoying ‘mdi-’ to ‘mdi:’
I’m not clear on how to use this material design icons.
Let’s say I want to use this icon: battery-50 from materialdesignicons.com
I got this when I select it:
Then I copy the mdiBattery50 and paste it on my home assistant sensor and add the colon:
mdi:battery50
Look at the cheat sheet.
Use exactly as written except with mdi- replaced with mdi:, so mdi:battery-50.
Also, if you declare or customise your sensor with device_class: battery, it will give you a dynamically-updated icon representing the charge automatically (docs):
You con do it from the mdi website too:
there is a difference between ‘B’ and ‘b’ - your ‘mdi:Battery’ is unknown.
but ‘mdi:battery’ does work !
UPDATE: I meant ‘mdi:battery-50’ does work
END OF UPDATE
Tiny point and bad luck that you did not copy but typed yourself.
But at least a lesson learned that with new stuff copy and paste is the past to start with.
Avoids headache - as long as the developer had done it right.
Cheeeers for your next battery (icon)
Yeah but it is not the 50% battery icon they were after.
sorry, I missed the ‘-50’
and the ‘B’ attery had caused the issue cause it really works
and it does not work with the ‘B’ as you can see here
Thanks for this site
