Users of Philips Hue light bulbs have reported that the devices switch to 100% brightness on their own. The owner of Hue, Signify, attributes this problem to compatibility with the Matter standard and notes that it may take about a week to resolve. This was reported by 9to5Mac.
Hue bulbs can be controlled in several different ways, depending on the model. The most advanced ones can be customized to any of millions of different colors, while others allow you to change the color temperature to choose a warmer or cooler feel.
What all Hue bulbs have in common is dimming, which can be adjusted using physical Hue switches, the Hue app, the Apple Home app, or Siri.
"After extensive analysis, we have identified an interoperability issue with the Matter smarthome standard, in which random temporary radio traffic disruptions are incorrectly recognized as legacy switch power toggles, turning low brightness lights to full brightness,” says the representative of Signify. “A permanent fix for the issue is in progress and will be rolled out within the next week.”
If you encounter an issue and don't want to wait for a fix, you can use any Matter controller app you're using to remove the Hue Bridge from your device list.
