Add note about "legacy" format to be used for OTA update from access point WebGUI

Hello!

When visiting a device via its access point, there can be an option to upload a file for an OTA update.

However, if the user accidentally selects the file in the “modern” (Factory) and not the “legacy” (OTA) format, the OTA update will fail with:

Update Failed: Wrong Magic Byte

It took me a while to find this:

Serial flash uses the “modern” format. OTA update uses the “legacy” format.

See related discussion:

Is it possible to add a note in this regard on the WebGUI that comes along with the AP and “OTA Update” section? And/or provide the detail with the aforementioned error message, e.g.:

Update Failed: Wrong Magic Byte - check correct OTA vs. Factory format

Thanks for your kind consideration and for upvoting it if you feel it is worth it👍

This appears to be a Feature Request for ESPHome, is that correct?

If so, it needs to go here:

The link you provided does not work for me. It gives a 404 error.

But thanks for upvoting! :+1:

The github link above?
My point is this will likely be closed because esphome feature requests are not valid here…
You need to put it there.
