Smart Buildings


MQTT (Message Queuing Telemetry Transport) is an ISO Standard Network Protocol particularly suited to smart technology and the underlying need to efficiently exchange vast amounts of dynamic building-wide status information, to achieve enhanced building performance and utilisation.

• Comprehensive Data Analysis
• Simmtronic Data Aggregation Architecture which enables rapid data provision
• Hosted on Robust Simmtronic SPC.2000 Control Processor with continuous operation
• Simmtronic MQTT Software Model publishes data directly without third party gateways

• Lighting Levels
• Occupancy Status
• Energy Performance (when purchased with Simmtronic energy monitoring toolset)
• Device specific data for Area Controllers, Light and Blind Control Modules, Sensors
• Gear and Lamp Faults, Maintenance reporting

The MQTT Architecture consists of three entities: brokers, publishers and subscribers. The broker is an intermediary between publishers and subscribers. Publishers, such as the lighting control system, publish data to the broker about all the assets in their datasets. The broker retains the latest data published for every asset; publishers need to send data for an asset only when the data changes.

The data structure of the Simmtronic lighting control system is tailored to providing rapid MQTT data updates for every lighting asset. Every Lighting Control Module continually collects data from every asset (sensors, light fittings) that it manages. Every Lighting Control Module continually sends the latest data to its Area Controller. Every Area Controller continually sends all this data to the SPC.2000. The Simmtronic IP Parallel Access architecture allows every Area Controller to send data to the SPC.2000 simultaneously.

Labels will be provided where required for fixing to lighting devices. QR codes for all lighting devices will be available at the lighting Head End.

In a smart building, all assets are assigned unique IDs. Large assets may have these IDs fixed to them in the form of labels with QR codes. This allows a maintenance technician to capture the ID onto a smart phone or other device, to allow replacement parts to be ordered. QR code capture ensures that the information is captured and forwarded without risk of typing errors.

MQTT allows a very flexible and scalable way to approach building applications. The Simmtronic MQTT Publisher is set out to gather data from the beginning continuously, it already has the answer.

Thank you Simmtronic, for your professional, fast and reactive support with the delivery of these projects.

Simmtronic have delivered a large number of technically challenging projects for DBS and consistently continued to provide outstanding service. Their support, guidance and help throughout the process has been exceptional, working closely with our design teams to ensure the right solution for the project and a sound understanding of the brief, with our delivery teams to ensure the installation and commissioning are trouble free and then providing fantastic after care to the customer. They have added true engineered value into the projects they have been involved in for Derry Building Services.

Simmtronic have been a valued member of the DBS supply chain for over 10 years. Their pro-active and collaborative approach to lighting controls from the design stage, through to commissioning is highly valued by both our Design and Delivery Engineers.

Over the years I have really appreciated the Simmtronic ability to provide responsive support and listening to projects and clients needs. More recently the Simmtronic team has shown the capability to embrace the connectivity requirements of the Internet of Things by quickly adding MQTT to their range of integration protocols. This will greatly facilitate telemetry applications in buildings and the development of interconnected solutions that will make buildings more usable and easier to operate.

Landsec have consistently used Simmtronic Lighting Control Systems across our new London developments for over 15 years. Simmtronic understand our requirements and get involved at the very early stages of schemes, assisting consultants in achieving the optimum design solution, often taking the lead.  They always overcome the programme challenges they are faced with on site, delivering a quality, fully tested and operational solution, on time and to budget. Simmtronic undertake the maintenance and servicing across much of our London portfolio, they have a customer focused and flexible approach that suits the needs of our business and as well as our customers.

Simmtronic as an organisation has been, for the last 18 years, by far the best performing and most reliable lighting control system I use. From design through to commissioning and soft landings with the landlord teams Simmtronic always deliver on my projects. Simmtronic technology evolution is not just pushed through like others, but rather properly tested internally first, giving us as client teams the assurance that what Simmtronic say they can offer is 100% delivered, an absolute must with fast track major projects.

Simmtronic has constantly been available at an early stage to engage both with the designers and the Contracting team to assist with design solutions and to test options. This ultimately assists us in de-risking the project during the commissioning phase which usually defines when the project is completed. Simmtronic is seen as ‘industry standard’ and it is always encouraging to see them involved.
