New and Noteworthy in SiteWhere Community Edition 1.9.0


The SiteWhere 1.9.0 release adds 30+ new features, updates, and bug fixes and contains a number of important architectural improvements.

Tenant Management

Improved Tenant Template Support

SiteWhere 1.9.0 adds a more powerful model for using templates to create new tenants. In previous versions, there was a single tenant template which was used to bootstrap all new tenants. The new architecture provides multiple templates which provide more options for creating new tenants. The tenant templates include a base tenant configuration file and can specify data initializers for various parts of the SiteWhere data model. When creating a new tenant, a starting template is specified. Templates included out-of-the-box include:
  • Empty Tenant - This template allows a tenant to be create with no data and a very basic tenant configuration. There is no longer a need to delete the sample data that was automatically loaded with previous versions.
  • Construction Example - This template loads the construction example data included in previous SiteWhere releases.
  • Air Traffic Example - This template loads the air traffic example included in the sitewhere-examples GitHub repository. It includes additional assets for planes and tracking devices as well as a default tenant configuration that is pre-configured to ingest STOMP data sent from the air traffic web application.
In addition to the templates included OOTB, users can add their own templates to make it faster and easier to bootstrap new tenants.

Tenant Lifecycle Persistence

In previous versions, SiteWhere always started all tenants when the server was restarted. SiteWhere 1.9.0 now preserves tenant lifecycle state so tenants that have been stopped will remain stopped on server restart.

Infrastructure Updates

Better Performance in Administrative Console

Previous versions of the administrative console were based on JSP as the view technology. Spring Boot and the embedded Tomcat container have performance issues with JSP, so we updated the view technology to use Apache Velocity templates. The result is a much faster web interface and a much smaller server footprint thanks to the removed transitive dependencies.

Upgrade to Log4J 2

SiteWhere 1.9.0 now uses Log4J 2 as the basis for all system logging. This provides better integration with the existing logging in Spring boot.

Upgrade Swagger Dependencies

In the pre-1.5 Swagger version used in previous versions of SiteWhere, Scala was a transitive dependency. The footprint was huge considering it was not a core server component. SiteWhere 1.9.0 upgrades to a non-Scala version of Swagger, which greatly reduces the overall server footprint. Thanks to dependency improvements, SiteWhere 1.9.0 is almost 25% smaller than the previous version.

InfluxDB Improvements

Updated Client Jar

Updates to the core InfluxDB server caused problems with previous versions of SiteWhere due to non-backward-compatible API changes in the database. SiteWhere 1.9.0 includes the latest InfluxDB jar, which fixes the errors reported by users that upgraded InfluxDB to 1.0+.

Event Processing Fixes

The were a number of bugs in SiteWhere 1.8.0 related to the hybrid MongoDB/InfluxDB model and event processing. All of the reported issues have been fixed along with a number of improvements for the hybrid model.

New and Noteworthy in SiteWhere Community Edition 1.7.0



The SiteWhere 1.7.0 release includes some major architectural improvements along with many new features and bug fixes.

Upgrade to Spring Boot Architecture

Improved System Bootstrapping

SiteWhere 1.7.0 migrates the core platform to Spring Boot, supporting a more standardized approach for encapsulating the server. Previous versions of SiteWhere were bootstrapped as a web archive deployed on a standalone Tomcat instance, which gave less control over many aspects of the environment. With Spring Boot, SiteWhere provides the core application logic and uses the embedded Tomcat support to allow the web artifacts to still be deployed and accessed as with previous versions.

Updates to Folder Structure and Environment

By not packaging inside Tomcat, the folder structure has been simplified a lot. All of the Tomcat folders and configuration have been removed since they are now supplied by the embedded Tomcat instance provided by Spring Boot. The configuration folder has been moved into the root folder, but all of the content is still backward compatible with previous versions. Likewise, the database format has not changed, so you can point a 1.7.0 instance at the configuration and database from a previous installation and it will work. Since Tomcat is no longer bootstrapping, a new environment variable, SITEWHERE_HOME, has been introduced to point to the SiteWhere root folder.

Amazon SQS Integration

SiteWhere now integrates with Amazon SQS, allowing SiteWhere events to be pushed to queues in the Amazon cloud. The integration uses a configurable SiteWhere outbound event processor, which allows logic to be applied in choosing which events are pushed to Amazon. For instance, you can add an event processor that only forwards measurement events from a specific device specification into Amazon SQS.

Outbound RabbitMQ Event Processing

A new outbound event processor has been added for forwarding SiteWhere events to RabbitMQ using AMQP. As with other filtered event processors, logic (including complex scripted decision logic) can be applied to choose which events are forwarded. Any device that can listen on AMQP can receive a live stream of events as they are processed by SiteWhere. For those that prefer MQTT to AMQP, there is equivalent support for live streaming over MQTT.

Get Started!

Download SiteWhere 1.7.0 today and check out the new features for yourself! The SiteWhere team is looking forward to your feedback on the new architecture and features.

New and Noteworthy in SiteWhere Community Edition 1.5.0



The release of SiteWhere 1.5.0 Community Edition adds a number of new features to the platform along with some other refinements and bug fixes. One of the main areas addressed is tenant management with the addition of new administrative console functionality for tenant configuration. In addition, another high-performance option is now available for ingesting events via the AMQP protocol thanks to the new RabbitMQ event source. Finally, a new symbology subsystem was added to allow for the generation of symbols such as QR-Codes for SiteWhere entities such as devices and device assignments.

Introducing Web-based Tenant Configuration

Before SiteWhere 1.5.0 tenant configuration was managed by editing the tenant configuration file by hand. While a viable option, the process was error prone and made it hard to understand the many features available in the platform. SiteWhere 1.5.0 introduces a new web-based tenant configuration editor that allows tenants to be configured in the administrative application.
SiteWhere Tenant Configuration
The tenant configuration editor is arranged hierarchically with the same general structure as the configuration schema. It allows for the editing of existing configurations that have been directly edited in the XML file for backward compatibility while supporting a much more intuitive experience going forward. Each node in the configuration is documented along with each configurable attribute. The user interface constrains attributes based on datatype so that invalid values can not be entered. Validation functionality is also provided to ensure that it is obvious in the web interface when child components are required.
The 1.5.0 release also adds the concept of staging to SiteWhere tenant configuration. After editing the tenant configuration, the new changes are staged in a separate file from the running tenant configuration. The next time the tenant is restarted, the staged configuration takes the place of the existing one and becomes the active configuration.

RabbitMQ Event Source Support

We have received a number of requests for integrating SiteWhere with RabbitMQ to allow another high-performance option for ingesting events. SiteWhere 1.5.0 adds a new RabbitMQ event source that uses the RabbitMQ Java drivers to connect to an instance and consume events via the AMQP protocol. Characteristics such as the number of consumer threads can be configured to maximize performance.
RabbitMQ Event Source

Symbology Management and QR-Code Supprt

It is a common requirement to have symbols that represent devices or other managed entities. These can include barcodes, QR-Codes, or even custom labels with images and other symbolism. SiteWhere 1.5.0 adds a new symbol generator manager that allows various types of symbols to be configured for SiteWhere entities. The first symbology plugin supports generating QR-Codes for sites, specifications, devices, and assignments.
QR-Code Support
The symbols are generated dynamically and can be accessed via the SiteWhere REST services. For instance, if you have a custom application and need to be able add QR-Codes to the web application or product packaging, a call to the REST service will provide the QR-Code image. Since the QR-Code plugin is configurable within the new tenant configuration manager, the look-and-feel of the code (size, color, etc) can be customized on a per-tenant basis.

Video Covering 1.5.0 Features

We have also added a new video to the SiteWhere YouTube channel covering the 1.5.0 features. Take a look at the video, then download SiteWhere 1.5.0 CE to try the new features out yourself!
