ZWAVE enable security

Hi

Going through some of the node files I noticed that some devices show unsecured connection. Is there a way to reconfigure them so they connect with security on?

Example from one of the node file below:

<?xml version="1.0" encoding="UTF-8"?>
<node id="9">
  <manufacturer id="335">Linear Corp</manufacturer>
  <basic-device-class id="0x04">BASIC_TYPE_ROUTING_SLAVE</basic-device-class>
  <generic-device-class id="0x10">GENERIC_TYPE_SWITCH_BINARY</generic-device-class>
  <specific-device-class id="0x03">SPECIFIC_TYPE_SCENE_SWITCH_BINARY</specific-device-class>
  <product-type id="0x5257" />
  <product id="0x3533" />
  <listening>true</listening>
  <routing>true</routing>
  <command-classes>
    <command-class id="0x70" version="1" name="COMMAND_CLASS_CONFIGURATION" type="supported" security="unsecured" />
    <command-class id="0x20" version="1" name="COMMAND_CLASS_BASIC" type="supported" security="unsecured" />
    <command-class id="0x72" version="1" name="COMMAND_CLASS_MANUFACTURER_SPECIFIC" type="supported" security="unsecured" />
    <command-class id="0x25" version="1" name="COMMAND_CLASS_SWITCH_BINARY" type="supported" security="unsecured" />
    <command-class id="0x86" version="1" name="COMMAND_CLASS_VERSION" type="supported" security="unsecured" />
    <command-class id="0x2B" version="1" name="COMMAND_CLASS_SCENE_ACTIVATION" type="supported" security="unsecured" />
  </command-classes>
  <configuration hash="2586AC8D122607220F86DFF5334578B5">
    <associations />
    <parameters />
  </configuration>
</node>

The only way to do that is to exclude the device and include it again with secure mode enabled (see Z-Wave Device Inclusion & Exclusion).
