Configuring Z-Wave Door Sensor

Hi, not really understand what needs to be done.

  • select the zwave device
  • In “Node Config Option”, choose “121: Report Type”
  • In value, set to"17" (as recommended). It says " To configure which sensor report will be sent when the Sensor is triggered Opened/Closed. Bitsets: 0->Battery report, 4->Sensor Binary, 8->Basic Set, Default setting: 0x00000100 (Basic Set). Ideal Setting for OZW is 17 (Sensor Binary and Battery Report)".
  • wake the device by simple clicking on the sync button. Wait a few seconds to see if the value is reupdated to 256, if so try again.

Why default settings is “0x00000100” while this field is accepting integer? Is it “256” the default value?
Why isn’t it done by default when the device is added in zwave, since its type is door sensor?
