I see you're including a hard-coded certificate, not sure if this is a good idea. Certificates expire, this one in 2031 which is a long time, but we'll have to make sure to keep it updated. Not sure about alternatives though.

Would definitely not be ideal for release.

Maybe should have kept my testing in regard to truly automatic updating out of this PR, immediatly ran into CPU exceptions while testing this code.

I have removed it from the PR and will consider revisiting this functionality in the future.

Instead I added two buttons on the /ota page of WebCfg (if update checking is enabled). One that will link to the latest release URL and one that is a direct link to the binary from /webflash in master. This would for now be the quickest way to update to latest.

This PR should be ready to go now, I've tested it without issue.

This is a long-time wanted functionality. :)

In reality I asked if it was possible to OTA flash from GitHub, to avoid the manual upload of the bin.

So basically have the device download from github and flash. Would it be possible?

Thanks a lot @iranl

Flashing the binary straight from GitHub should be possible, but too complex to make it part of this PR. Will probably revisit when I'm done with open issues I can contribute to.

I thought the upload was more complex than a GET from an URL. My bad...:)

I'm too used with Tasmota.
