New Z-Uno software release 2.1.3

This new software update for Z-Uno adds the support of the best in class IoT security protocol — Z-Wave Security S2.

What's new in 2.1.3?

New features:

  • Z-Wave Security S2 implemented!
  • MultiChannel is supressed if only one channel is defined (no duplicate widget will be shown in your controller).
  • Associations reworked - up to 32 groups are now supported (1 LifeLine + 31 control groups) with up to 8 nodes in each group.
  • User libraries can now be located in the sketch folder.

Bug fixes

  • Fixed Wakeup CC (broken since 2.1.1).

Notes on Security S2

  • To benefit from the newest Security S2 you need to own a modern S2 capable controller.
    RaZberry users can check the beta v3.0.0.
  • You need to change the bootloader from non-secure/S0 to S2 version. This is done by selecting S2 from the menu Tools→Security (see the screenshot). Then do Tools→Burn bootloader. If bootloader mismatch your menu settings, you will get a warning.
  • To locate the Z-Uno PIN (also known as DSK or ZWS2DSK) check the log of the Arduino IDE (see the screenshot).
  • Z-Uno supports all security classes: S2 Unauthenticated, S2 Authenticated and S2 Access.
  • S2 capable bootloader do not support S0 security, Z-Uno can autodetect the security scheme used by the recepient, so it can control devices with any S2 security level provided the corresponding key is granted to Z-Uno.
  • Z-Uno with S2 support can not control/support S0 security scheme. If you need to control actuator with S0 security only, either downgrade to S0 your Z-Uno or use rules on the controller to receive S2 sensors notifications and send S0 commands to the S0 capable actuator.
  • In S2 variant of Z-Uno the user code is limited to 6 Kb only. This is enough for most of your sketches.
  • This is a not yet certified Z-Uno software - we plan to certify it soon in the Z-Wave Alliance.
