Can't delete lyric/water sensor devices. Open app, open device, just a white screen telling me the device is offline. There's no Gear icon on the device pages to delete a device. There's also no conceivable way to change my email address other than to delete the account? But you have to delete your devices to delete your account.... 2022 Update: you can only delete Online devices. If a device is offline, the app does not have a way of removing it.
