Is there any way to send a “All on” or “All off” signal to Z-Wave devices? My Qubino DIN dimmers has a setting for Activate / Deactivate Functions ALL ON / ALL OFF (“DIN dimmer module responds to commands ALL ON / ALL OFF”), which suggests that it is possible.

Thanks. I would love a little more detailed explanation: such as HOW do I send a ZWave multicast command (or should that not be broadcast and not multicast?) in Home Assistant?
I’m using Z-Wave JS UI btw, and I am also a Home Assistant newbie, although reasonably experienced with other systems from X10 20 years ago to Hubitat today.
