First spotted by u/PhilDunphy23 on the HomeKit subreddit, the Eve Degree has new firmware available to download, bringing the device up to version 1.2.4 (1075). While the headline feature of the update mentions improvements to “battery level display”, the company has also provided several enhancements for device owners with regards to temperature readings. Here are the full release notes:
This update improves the battery level display. If updating fails, your current battery level may already be too low, in which case you should insert a new CR2450 battery, and try again.
Air pressure is no longer temperature dependent.
Minimum altitude has been extended to -450m
Fahrenheit measurements above 100 degrees display correctly.
