The bulb has only one channel of communication in the event of network failure by which it could show an error code. Blink codes. It'll be the old BIOS-beep thing all over again.
One short, two long, one short, pause... Ok, that means... incorrect supply voltage? Oh, no, that's the reference book for the Amazon brand, this is a Phillips brand. Which means the code means... it's not on the chart! Or is this chart for the first revision? No, they changed the codes on bulbs after 2021, so... got it. One short, two long, one short, pause means "Unspecified error." Screw that, I'm getting an old-fashioned manual bulb.
Biting the hand that feeds IT
