We recommend switching over to the new JS integration of Home Assistant to have all of the advanced settings exposed.
Zooz products are now officially integrated with the new ZWaveJS integration of Home Assistant. If you're experiencing issues with accessing the advanced settings of your ZEN24 we would recommend first updating to the JS integration then excluding and re-including your device to your network in order for it to be recognized correctly.
For earlier integrations:
If your ZEN24 dimmer uses firmware version 1.05 or earlier, then you should have access to the advanced settings immediately upon inclusion; no extra configuration should be needed. However, if your ZEN24 uses firmware version 3.0 or later, you'll need to add a new XML file. This is because Home Assistant doesn't have a way of distinguishing a device by firmware version; all other device identifiers are the same. So the first thing to check is the firmware version of your switch.
If your dimmer uses firmware version 3.0, you can access the advanced parameters by loading the XML file for the device using the instructions and code in the Home Assistant Device Specific database. Scroll down to the section for the Zooz Dimmer ZEN22; while this is a different model, the same code can be used for the ZEN24 since they are nearly identical devices. Remember to stop the Z-Wave network when updating the file, and be sure to exclude the dimmer from the network before loading the XML file. Whether your dimmer is using firmware version 3.0 or later, the XML file should be good for any of these firmware versions.
Alternatively, you can use the Call Service command shown in the screenshot below to manually adjust selected parameters. You'll need to manually input the node_id of the dimmer, then enter parameter number, desired value, and size (it's usually 1 but can also be 2 or 4 [byte dec] so please check in the manual that comes with your device).
