It's an Internet connected device that will never receive updates and has none of the features that justify its existence above a $20 dumb thermostat. If you inherited it and don't care about the features and never used it anyway, I'm not sure why you'd care either way.

If you'd bought it for hundreds of dollars for the things it promised to do, you'd probably be much more excited to learn that you at least aren't stuck with a device that was made intentionally dumb by the manufacturer. They're perfectly capable of doing what they were designed to do!
