Yes, this is possible. There are several ways to do this.
1. with a GRAU App remote control (see info)
or
2. with a GRAU App transmitter for wall switches that is installed in your switch box and an additional button cover for your installed switch programme (see info)
or
3. with a casambi-compatible EnOcean push-button
Your lights equipped with the GRAU app control can be switched and dimmed or scenes and animations can be called up without having to actively use the app. Nevertheless, you will need the app for the one-off setup and connection of the switch components with the light.
Important note: if a dimmer is installed in your switch box, it must be removed before installing the luminaire with GRAU app control, as these components are not compatible with each other.
