Changes: 

  • The following problems have been fixed:

    • Importing a valid EnOcean or LoRaWAN Device Interface (XIF) definition sometimes failed in SmartServer 4.3. (AP-13616)

    • In some cases, the LON driver did not work in SmartServer 4.3. (AP-13573, AP-13627, AP-13653)

Warnings: 

  • EnOcean has completed limited quality assurance (QA) testing of this update. Only use this update if you need any of the fixes addressed by this release.

  • When you access trend reports with many logged datapoint values, CMS web page updates may be slow. Close any trend reports to restore normal performance. (AP-11847)

  • The SmartServer includes a 32 GB SD card.  You can run out of free space on the SD card if you create many backups or retain too much data in the data log, and performance will degrade if the storage for logged data exceeds 100 MB and will degrade significantly if the storage for logged data exceeds 400 MB. The SmartServer requires a minimum of 8 GB free space on the SD card for normal operation. For optimal performance, always keep 8 GB of free space on the SD card and keep logged data below 100 MB.    The Datapoint Properties widget displays an estimate of how much SD card space will be required for logged data based on your data log configuration.  You can use this value to manage the space required for data logs and keep the size below 100 MB for best performance.  If required, you can free up space on the SD card by reducing the frequency and retention period for logged data and by deleting backups.  To delete backups from the SD card, see Backing Up, Restoring, and Cloning the SmartServer.

  • The SmartServer 4.3 software will not run on SmartServer hardware with a dual core processor.  You can determine which processor you have by reading the label on the bottom of the SmartServer. The serial number printed under the product name includes one letter. If the letter is F or later, you have a quad core processor. If the letter is A through E, you have a dual core processor that is not compatible with this release. 

  • In some cases, the CMS displays stale data after you make a change.  If a datapoint value, context, preset, or other value is not displayed as you expect, refresh your browser window (Ctrl-F5 in many browsers).  If you are using the CMS Datapoints widget, you can click the Refresh button in the upper right corner of the widget. (LUM-7145)

  • You cannot set the latitude and longitude for a SmartServer by typing new values in the Devices widget. To change the latitude and longitude for a SmartServer, you can either drag the SmartServer icon to a new location on the map in the Devices widget, or you can enter new values in the Planning widget. (AP-11085)

  • In some cases, connections with many destinations may fail to update all destinations. If you have any connections with many destinations, test them to verify all destinations are updated as expected. If you observe any failed updates, break up the connection into multiple connections with fewer destinations per connection. (AP-9259)

  • In some cases, the CMS Sequencing widget may get stuck with an Adding Flows to Workspace message. Restart the SmartServer to eliminate the message. (AP-11297)

  • In some cases, when you create a connection between two LON datapoints, the devices involved in the connection may be deprovisioned.  You can recover by reprovisioning the devices after they become deprovisioned. (AP-8360)

Changes: 

  • Use the SmartServer with large EnOcean networks with the new EnOcean Remote driver for the SmartServer. The EnOcean Remote driver for the SmartServer uses EnOcean’s IoT Connector (IoTC) to integrate with EnOcean devices communicating with EnOcean radios in Aruba and Cisco access points. This solution leverages the large building scalability offered by Aruba and Cisco access points and enables you to integrate the SmartServer with all the EnOcean devices that can be accessed by the access points in a building. (AP-12043)

  • Get support for more types of EnOcean devices with added support for EnOcean EDRPU, EMCS, ETHS, and STM550 devices. (AP-12108)

  • Get information on non-BACnet devices that are down when you access them from a BACnet workstation through the SmartServer BACnet Server. (AP-10558)

  • Use the SmartServer Pi software introduced in the 4.2 release with LON devices. Using SmartServer Pi software on your own Pi-compatible hardware you can now integrate with LON devices in addition to BACnet/IP, Modbus TCP, and Modbus RTU devices. (AP-12823)

  • The following problems have been fixed:

    • Viewing large data logs in the CMS Datapoints widget sometimes failed. (AP-12807)

    • Renewal of signed security certificates sometimes failed. (AP-12413)

    • In some cases, the SmartServer event scheduler would quit working after a change into or out of daylight savings time. (AP-12592)

    • The SmartServer sometimes deleted connections between SmartServer internal applications and LON edge devices on startup or restart. (AP-12511 and AP-12332)

    • LON datapoints using user-defined datapoint types could not be selected when creating a schedule event in the Calendar widget. (AP-12287)

    • In some cases, the SmartServer did not set the BACnet Current Command Priority property for a BACnet object after updating the Present Value and Priority for the object. (AP-12418)

    • IAP updates to a BACnet datapoint without a specified priority used priority 16. They now use normal priority which in IAP is encoded as priority 17. (AP-12475)

    • The SmartServer BACnet Router did not forward all qualifying BACnet messages. (AP-12417)

    • The SmartServer BACnet Router sent valid reject messages to the incorrect destination. (AP-12416)

    • When you enable BACnet on a SmartServer Pi, you will receive a new notification to open the required IP ports on your Pi. (AP-12963)

    • BACnet routing has been enhanced to prevent looping errors in unusual configurations. (AP-12795)

    • Performance and reliability of BACnet trend logs and schedules have been improved. (AP-11257 and AP-11258)

    • Logging from Node-RED has been reduced to prevent informational events from filling the flash drive on the SmartServer. (AP-12964)

    • In some cases, the SmartServer displayed an error message when you enabled Modbus RTU for one of the RS-485 ports. (AP-12081)

  • Advanced Intrusion Detection Environment (AIDE) is disabled by default. If your system security policy requires running AIDE, then you can enable this process to run once a day using the SmartServer System Configuration page. Enabling AIDE to run a daily cron job places a heavy demand on the CPU and filesystem that can impact system performance. See Configuring Advanced Intrusion Detection Environment (AIDE). This feature is not available for SmartServer Pi. (AP-11975)

Warnings: 

  • LON RNI may fail with this release. Use a different release if you required LON RNI. (AP-13627)

  • In some cases, importing a valid EnOcean or LoRaWAN Device Interface (XIF) definition may fail. Use a newer release if you need EnOcean or LoRaWAN support. (AP-13616)

  • When you access trend reports with many logged datapoint values, CMS web page updates may be slow. Close any trend reports to restore normal performance. (AP-11847)

  • The SmartServer includes a 32 GB SD card.  You can run out of free space on the SD card if you create many backups or retain too much data in the data log, and performance will degrade if the storage for logged data exceeds 100 MB and will degrade significantly if the storage for logged data exceeds 400 MB.
