I just got my C7 today, and going through the basic setup. I have three Ecobee thermostats plus one sensor that I've given custom Labels in Hubitat. I enter the new label, click save, and then in the main device list everything looks good. However, some period later (few minutes?) the labels revert back to their default value. I'm not going crazy, as I've renamed all four devices multiple times and they always revert back. So far, other devices appear to be keeping their custom label.
What's going on? Elevate C7 with latest firmware updates.
