Via Twitter (sorry, I can’t get used to calling it anything else), it seems that Hue have confirmed that they will soon require all users to have a Hue account.
Hello Mysk, thanks for reaching out. Believe us, this change can only benefit the users, when it comes to security. Soon it will indeed be mandatory to have a Hue account in order to control the lights.
It’s worth looking at the responses to the thread, to see their (in my view highly spurious) reasoning that it is around security. At one point they make the comment about it being for targeted marketing based on products already owned, which I think is more likely.
Edit: this post here, among others
We want to reassure you that your system will still work without an internet connection. After creating an account, your data will not be sold to any third parties, and you will only receive marketing communications based on your device and account preferences.
Either way, I am not impressed and suspect many other MPU folk won’t be either…
