Turning on lights when lux levels falls

I’m trying to switch on my living room lights when the lux levels in our conservatory fall below 100 lux and can’t get it to work.
I want the lights to start a 0% and increase to 75% in 15 minutes but I don’t want them turning on and the resetting there values, causes a brief flash of light.
Can someone please point out the error of my ways.

thanks in advance


One way to do this – I have a piston that turns off all lights at bedtime. Part of this piston is setting the level of my lights to 25% and then turning them off. Then my evening fade-in piston is just a single statement – fade to 100% in 30 minutes. No flashing lights and it’s very smooth. You shouldn’t need the turn on command as the fade level should turn them on. At least it does for Sylvania Lightify bulbs.

That’s a workaround but only works if you don’t manually set your lights in between. I haven’t found a way in CoRE/webCoRE to set levels before the lights come on. All of mine are Hue lights and that may be the reason.
