ZWaveJS-UI has “Scenes” but this really just sends a command to each device in the group. If there are many devices in the scene, sometimes one or more don’t actually get set, and the devices don’t all change at once. ZWave has a Command Class for this use case, and some of my ZWave devices support this, but none of the Zooz devices do. The term “scenes” has many meanings in ZWave, but in order to control multiple devices with one radio command, CC 43 and CC44 need to be supported by the devices. 43 to send the command, and 44 to configure what each scene does to the device.
Would this be considered by Zooz? FWIW, I have a lot of Zooz ZWave devices, and this is the biggest thing missing for me.
