Turn Off Light when switch is On

Hi All
I have a Sonoff Mini that is conected to a Projector screen relay. When the Projector is turned on, The Sonoff Mini is displayed as On.
I have a MiLight which is synced to 8 GU10 Lamps.
In my Home Assistant, I can see the status of the switch from On to Off depending on the Projector.
I can also from the Overview turn the Lights On/Off or change colour.
In the automation I have set this up, thinking the For is 1 second, but not really bothered about that, but it does not work.
Any pointers please?
Thank You

You might want to read up on conditions and services in the documentation. Conditions don’t change things. Services do.

Cheers pal.
It was all rush to experiment but will check them out
Thank you
