nuki_hub: M5Stack Atom S3 Lite not working

Hi all,

First of all: Apologies if this issue should be reported somewhere else. If so, please let me know.

I’m quite newbie on this ESP32/IoT stuff but recently received a Nuki Opener and I wanted to integrate it into Home Assistant without Nuki Bridge using your solution. I read M5Stack Atom Lite was recommended so I bought it… sort of, because the one I bought by mistake (I wasn’t aware of differences) was the S3 one (https://docs.m5stack.com/en/core/AtomS3 Lite) and… I’m struggling trying to install Nuki Hub on it. I’m not even sure if it is compatible at all 😦

From web installer I get this:

So I tried using espressif_download_tool. I have no errors

But the ESP32 AP doesn’t appear so I just wonder if maybe this ESP32S3 is supported.

From 8.24 release notes I can see “Arduino Core for ESP32 to version 2.09” which is the latest and, appartently ESP32S3 are supported (https://docs.espressif.com/projects/arduino-esp32/en/latest/getting_started.html#supported-soc-s) so I guess it should work with nuki_hub and just maybe something should be tweaked at flashing process?

I will really appreciate if confirmation can be provided about this and, if it is not supported I will be glad to provide the information I can to help to test it.

UPDATE: I’ve been reading and finally tried the esptool method to deploy the files. It seems to confirm ESP32-S3 is not being supported. Is it planned to support it in the future?
