Received an email from meet the hue,

'Your Hue Bridge was reset to factory defaults and has been disconnected from your Hue account'

The email passes SPF and DKIM so seems to be a genuine email.

Have logged into my hue account and yes indeed by hub has gone from my account.

I'm at work at the moment so cant check the device. There is nobody home that would reset the device.

Has anyone experienced this?
