Which platformio_options are you using to make it work?

Initially I had some errors too. Then I found out that any device Id that isn’t exactly what you have will prevent the yaml file from loading and it will throw an error.

Now it seems to hang on Unpacking … but I leave it for some time to see whether it will come to live

If you don’t have this device, devils_ivy_moisture, in your HA setup, then it will throw an error.
Same for the other one.

I’m seeing the same loop on boot
I’ve updated the devils_ivy_moisture and outdoor_temperature to be valid sensors in my home assistant but still not working

I got this screen working an even used the LVGL (BETA) component in ESPhome.

GUITION 4" 480x480 ESP32-S3-4848S040 Smart Display with LVGL

[480px_screen] https://www.aliexpress.us/item/3256806618705053.html I have been seeing these a lot of Ali lately for around $27. They check all the boxes for me Fast CPU Lots of memory Great format Easy wall mount as a wall switch 120v relay included Does not require programming another internal device for LVGL like NSPanel Many thanks to everybody on the ESPhome discussion board for helping me get this working. I initially tested it with the openHASP project. This works very well but you …

I found the root cause. It’s a USB port problem.
I’ve switch to another USB port and it now works. No more constant rebooting.
