Also looked at the datasheet and yes, it has only analog outputs (DAC_L/R & SPK+/-).
Maybe we could use an external ADC, this should work as described here: Using ADC to get multiple audio streams · pschatzmann/arduino-audio-tools · Discussion #694 · GitHub
But i think the easiest way is to build some “simple” sounds into the firmware.
@pOpY with this configuration
I have got a poc with a local flac file and with a stream. The next two weeks i will start to work that out to a usable solution and integrate it with the alarm clock. I will also try to create detection if there is really sound coming from the speaker.
WOW, that sounds really nice!
I hope i will have all partts for the clock to assemble one and try it out.
@EnsconcE Can you please upload the “materialdesignicons-webfont.ttf”.
It’s missing in the fonts folder and when i use another from github it’s stating missing glyphs.
thx
If you need nice local alarm sounds, big A has some for us 
Here is a link with an list of nice echo show sounds to download: Allow to query available notification sounds · Issue #5 · Apollon77/alexa-remote · GitHub
Until the local playback feature is available, i have added those in the www/media folder and added them to my esphome yaml like:
http://homeassistant.local:8123/local/media/xxx.mp3
I have also looped them with ffmpeg so the final length is ~5 mins for every sound. Should be enough to wake up If you need it i can provide it.
It seems for now that only a file of about 20secs can be uploaded. The advantage is though, that it can loop endlessly. So local files should really be seen as a last solution to the no internet connection problem…
Nice, thx for your efforts!
In your SOAS implementation, can you please also allow the user to select the local file as a primary alarm sound?
So regardless of wifi, internet and so on … just the local alarm sound can be selected and will be used.
Sure, optionally use an HA/internet stream (as it is now).
In our case the SOAS devices are just alarm clocks and they should be reliable
If you need help i can also try to implement/test things out on my hardware.
thx
I have just pushed local file support to the dev branch. @pOpY @DieOuweGek, if you have the opportunity then please let me know if you have any remarks.
As for your question about alarm clock only @pOpY. The main goal of this was to be able to stream an internet stream and then have a fallback to a local file, which is now finally available. If local only is implemented, a lot needs to be reviewed and i think it’s not really worth it. If you provide the HA url and use the same file locally, then there is no real difference (only max 5s delay before local kicks in due to detection things if internet is not available). You could probably even point out to a bogus URL to have the same experience even if there is a connection. Another difference will be there when your file is too large to be able to be flashed onto the esp, but then you could use a smaller file for almost the same experience…
I have ordered all the bits, but for the visually impaired…me with glasses… how would this bigger screen go?

It would not make a difference… Everything is hardcoded when it comes to location and size.
Wow, nice!
Tested the local fallback and it works as it should!
So now, when there is an internet/wifi issue, the alarm also goes off.
I have converted one of my amazon alexa ,mp3’s to flac and it plays flawlessly.
Reegarding fallback:
I understand your decision and in the end, it does’nt really matter.
The main point was an fallback, and now there is this feature.
thx, for also adding the raising volume feature and including my weekday language feature.
I have made tqo PR’s regarding following features:
Maybe time for another release after merging? 
Keep up the good work.
pOpY
Thanks, will look into those. I have just pushed my changes to the master. I will look into your PR’s seperatly. It already was a big change, so i did not want to stretch that any further.
Yeah, just let it settle.
Just ping me when you want to review, discuss and hopefully merge my PR’s.
On monday i am (and my wife) are back to work (from vacation), so both SOAS devices will be tested in real life 
Just updated to 2025.8.25.2, i also noticed i was living in the future 2 days ago, the sleep timer did not work anymore. That is fixed now
Nice!
I dont use the sleep timer
Commented all PR’s and pushed an new one of the “display on” feature.
Just released 2025.9.7.1, see changelog below. Thanks to @pOpY for some nice features. There is also an update for the STL files, only the SH1107 has been updated. I will update SH1106 in the near future. With this update, a module can be shoved into the inside of the clock. This way the clock becomes a bit more dynamic.
The next release will focus on more modules, but also support for the ESP-IDF framework and for the Arduino framework.
time_sync_done is now set by checking the local clockcheck_alarms script is now single mode2025.9.18.1 went to the main branch moments ago. Big, and unfortunately breaking, changes. Support for arduino framework is back due to stability issues with the esp-idf. With arduino there is also custom support for local files, by means of a local audio stream server. It’s all now a bit more flexible.
This release also contains a lot of modules, mostly done by @pOpY
Alarm on local after secondsnight_mode detectionNICE! Thx for all your efforts!
The 3d print files have been updated
I added this possibility of a tactile switch due to crowdedness in the housing. With these printable files the space used is less then the flathead button and with that it becomes easier to put the clock together.
