Flashing a custom Firmware to Sonoff DIY devices, from the factory firmware

I've tested all "sonodiy" actions, except the 'flash' command. Because I currently have only one device, and flashing it can not be reversed to the factory firmware, so I would'nt be able to make further tests.

It should work asis, if the device accept an external URL, as the default Tasmota one currently configured in the config-sample.php file.

If it fails, it might be necessary to download the firmware directly to a local web server, and then change the URL according to the new location.

  • Try with a local hostname, ie:
    http://mycomputer.local/firmare.bin

  • or even directly with an IP address, ie:
    http://192.168.0.123/firmare.bin

I would appreciate if you could PLEASE report if it works correcly and what were the exact steps that you tried.

Thank you

as I feared, the ota_flash endpoint only accepts a local URL ( on the LAN), and silently ignore externals urls.
So first download the firmware to a local webserver, and use this URL to flash!

use the latest 2.05b2 version
espbuddy.php self update 2.05b2

Then try adding the -P Option at the end of the flash command, and please report if it work 🍺

it means OTA has NOT been unlocked (while the device doesnt first report any error) ,

try to reboot the device, and send the unlock command again.

You can check if if has been really unlocked, using the sonodiy info command.

If it still failed, it might be the Sonof factory version which need to be updated first, or may be they changed the way the unlock command work in recent firmwares.
I dont know, and can not help anymore. You'll have to investigate

If you make any progress, please be kind to report it here to help others, by opening a NEW issue, regarding this specific topic, or even better, push a PR.

senadaruc - did you ever get your Sonoff to flash? I'm having the same problem with a Sonoff mini r2.
