Changing the "Backlight" colour on Philips Hue Bridge/bulbs

Hi,

Quick question. I've got my Philips bulbs out of storage and noticed there is a handy feature in Hyperion to set "Backlight Threshold" and (seemingly, unless I misunderstand it's purpose) this allows the bulbs to act as normal lights (lamps in my case) when Hyperion is inactive/black screen detection.

This works flawlessly, Hyperion has picked up the bridge and is working the bulbs fine. When the device (Firestick) is powered off or goes into black screen detection, after a second or two the lamps fire up, honouring whatever "Backlight Threshold" is set to.

But it's always cold white. Is there any way to change this to warm white? I've tried changing it via the Philips android app and it doesn't stick, next power cycle of the firestick they come back up as cold white. I'm not sure if this colour is picked/commanded by hyperion as maybe there is some hue setting that I haven't found. Selecting "Coloured backlight" and even changing the temperature of the bulbs doesn't do anything.

I've attached my config but note there's a lot of shittery in there. For some reason my PI5 SPI broke and I've been messing with the config until I found it was the PI itself, not Hyperion, as even the feedback loop doesn't work.

Thanks!

Hi,

Yes there are multiple apps. So far as I can see all are published as official Philips Hue apps.

I've no idea why, but it could be related to the fact that Ambilight/Hue division are not actually part of Philips. Or at least certainly not under the same umbrella.

Either way, yes, finding the right app and changing the settings does indeed allow me to pick the colour it defaults to when streaming stops.
