Beeping Philips Hue products are a rarity, but with the sheer number of products sold, it is noticeable. Recently, it was mainly the Play Lightbars that caused problems. Already a few weeks ago, Philips Hue admitted to this error, which can cause a beeping sound with the Play Lightbars, especially with very bright light settings.
Now there seems to be some movement on the issue. As the support of Philips Hue informs, they seem to be working on a firmware update for the Hue Play Lightbars. Literally, the mail sent to affected users says:
To resolve the issue with your Hue Play Lightbars causing noise during operation, a software update will be available shortly. This will be available by 1 May or earlier and will fix the bug. The update created will replace other troubleshooting tips or hardware replacements. For this reason, the replacement of the Hue Playbar Powersuppy will not be arranged.
By the way, this is not an unusual procedure. Already with the GU10 spots, the beeping could be fixed with an update of the firmware without it having an effect on the brightness or the colours. But please don't ask me how Philips Hue does it…
