NSPANEL after flashing on esphome and connecting to 230V, the Sonoff firmware is running again

[siminkuv]

When I flashed from esphome to homeassistant, the ESPHOME firmware was loaded. Until I flashed, the display was even on 3.3V and the USB converter. Since the flash, the display has not been on, but only flashing via Wifi works, not via USB flash. I tried connecting the board back to the main board with access to 230V, but the display started with the Sonoff logo and their interface. Does the board have two firmware? Thank you

Does the board have two firmware?

I don't think this is the case, bit it does. The bootloader keeps two copies of the firmware (an old one and the latest) for the case the OTA fails.
It should manage this and only boot from the latest, but it can (unlikely) happen some issue that drives the boot to the incorrect partition.
Flashing it again should solve this issue.

But if yiu are understanding the Sonoff firmware is running due to what you see in the screen, that mi might not be correct.
Before opening your panel again, please try to find it under Settings > Devices and Services > ESPHome. If you find it, just select the model and click "Update TFT" as that will update the firmware in the display itself (it has its own controller separated from ESP32) and that should do the trick.
