Due to some design issues with esphome, sometimes showing success doesn't mean the firmware is updated. Finally, the version date shown on the device page in Home Assistant is used as a reference.

Return to HA's device page, refresh the page, and observe if the version information(SCREEK Version) changes, and if it becomes the new version, then the update is complete.

FAQ

Page becomes unresponsive on the way to update

If there is a situation like not being able to open the page on the way to update, this may be due to a weak signal and untimely response. You can try to bring the sensor closer to the wireless router and try again with a better signal.

You can also rule out whether the downloaded firmware file name has special symbols, browsers may add a bracket suffix to the file name when repeatedly downloading, this may also cause problems on very few browsers.

Show duplicate HA attributes after update

Some firmware versions modify the parameter configuration of the attribute, resulting in a new HA attribute, while the old one becomes unavailable. This does not affect usage, if you want to remove them, remove the device from HA and re-add the device. When re-adding, you may need to reboot HA once since HA will not find devices that have already been added, or you can manually add them using the sensor's IP if you don't want to reboot.

Duplicate properties after firmware update can be eliminated by re-adding the device.
