This upgrade has several enhancements to improve the reliability of the Z-Wave communications. Most notably there is now a ‘Heal & Diagnose Network’ feature that you can run overnight to do a thorough test of your network and report the reliability of communication with all the nodes.
This upgrade also fixes an issue adding codes with the Schlage lock and dual set points for the thermostats. Also, all events are now logged on findvera, so you have a detailed list of every time a door is opened closed, a sensor is tripped, etc. And, you can associate cameras to door locks so you have a video archive whenever someone enters the door.
