We recommend switching over to the new JS integration of Home Assistant to have all of the advanced settings exposed.

(This is a discontinued product, replacement model: ZEN73)

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 ZEN23 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 ZEN23 switch 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 ZEN23 uses firmware version 3.0 or later, you'll need to add the 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 switch 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 with the ZEN21 On/Off Switch code; while this is a different model, you can use this same code for the ZEN23 since these devices are nearly identical. Remember to stop the Z-Wave network when updating the file, and be sure to exclude the switch from the network before loading the XML file. Whether your switch is using firmware version 3.0 or later, the XML file should be good for any of these firmware versions.
