Regarding the number of devices affected, Signify’s representative said, “Our data shows fewer than 100 Philips Hue Bridge Pro devices have been impacted.”

When asked about the update’s purpose, the spokesperson noted that Signify “regularly provides software updates that deliver improvements, security updates, and bug fixes,” without providing further detail.

“We have identified the root cause and are implementing a fix to prevent additional users from being affected. As this relates to a specific technical implementation, we won’t go into further engineering detail,” Signify’s representative said.

Philips has started rolling out an update to prevent additional devices from being bricked. Customers whose devices are already broken should contact the Philips Hue support team, the company rep said. They added:

We will replace affected Philips Hue Bridge Pro devices free of charge, regardless of warranty status.
