Hi all,

And thanks already for your help ! 😉

In the next days, it’s Halloween and I would like to know if it’s possible to make thunderstorm effect with 3 gu10 spot that I have. Just to give you a full view and the GU10 are directly connected to Homey (no gateway)

Do you have an appli or a configuration (flow) in home to make this effect ? The trigger will be a doorbell or motion detector the mots important is how to configure the « than » in the flow.

Thanks all for your help !

Regards

Cédric
