Twinkly Lights turns on at 0% brightness

I bought the 500 LED Twinkly Lights and set it up in HA, but it constantly turns on at 0% brightness so it looks like it isn’t on.

I’ve tried setting its entity with 100% brightness, as well as setting up a scene with 100% brightness – but none of these work; it still turns on at 0% brightness.

I did initially find a (now closed) bug in Github from 2022 about this issue (can’t find it now)… but for me, setting brightness via automation entity or scene doesn’t make a difference. I have to manually turn up brightness via dashboard.

Is anyone else having this issue? Does anyone know how to fix it?

I seem to remember a few threads here about an issue with certain lights not applying the brightness setting if it’s set with the turn on command.

Can’t find the threads right now, not was it specific to twinkly. However the workaround was to turn on the light with no specific brightness,wait a few milliseconds, then set the brightness via a separate call.
