If you bought an OpenDTUFusion Board that had a pre-flashed firmware, you might lose radio module connection after using the generic OTA image when you OTA for the first time, as the baked-in pin assignments get overridden. If that is the case for you, please load the openDTUFusion-specific device_profile JSON to restore them, they will then also be retained over future OTA updates. The How-To for that is here: https://github.com/markusdd/OpenDTUFusionDocs/blob/main/FLASHED_START.md#loading-a-device-profile-for-the-rf-and-display-pinout
OpenDTU now offers generic ESP32-s3 builds here. For the Fusion board, you need the USB version (as we use the in-built USB and no external converter):
For Over-the-Air (OTA) updates, download the non-factory .bin marked in green.
Then go to the web interface, select and flash it.
Wait for it...
Done.
