It all starts with lighting
Ideally, the LEDs should meet following technical requirements:
- 18 – 48 Volts DC
- 100 – 700 mA
- Max. 34W system power
To ensure maximum lighting efficiency, our sensors continously measure the current room light level
The integrated ambient temperature sensor enables an intelligent control of HVAC, reducing operating
costs even further
Our sensors with BLE-Technology are able to send and receive Bluetooth data in real time, allowing for various Smart Building use cases
A centralized AC to DC power conversion for maximum lighting efficiency. Distributing power to all fixtures via LED smartsensors and smartgateways. Further LED drivers or active components are not required
The smartengine provides a sophisticated level of control which significantly reduces energy consumption. Multiple smartengines can be linked together to power and control hundreds or thousands of sensors and fixtures. The real time sensor data is being transfered to the smartdirector
2 power supplies per engine and a room distribution of fixtures to several smartengines guarantees a safe building operation. Additionaly the smartengine software also runs partially on every smartengine
The collected sensor data is stored locally at the director for up to one year. The director is accessed using SSL or TLS 1.2 encryption
The smartdirector is responsible for the logical management of up to 40 smartengines and 2,000 sensors
Integrated open API and BACnet/IP interface for 3rd party applications and building management systems (BMS)
Learn more about our OpenAPI and BACnet/IP interfaces
With BACnet/IP, you can establish two-way communication between smartengine and your building management system (BMS) and its subsystems (e.g. your HVAC system). This allows to decrease utility costs by up to 34% as you can use the sensor data to optimize building operation.
Main BACnet/IP Use Cases:
- Presence-based control of ventilation, heating and air conditioning
- Manual control of devices (eg. switches)
The Open API is used to integrate 3rd party applications into your smartengine solution. With our open API (rAPI & uAPI) you can access all of your smartsensor data. Main Open API Use Cases:
- 3rd party applications integrations
- Voice Control (e.g. Alexa, Google Home)
- Indoor Navigation
- Room & workstation booking
- Light fixture dimming via App
- Security integration
- People & asset tracking
- Space utilization and other analytics
- smartengine applications and system management
"We're using smartengine data in digitization solutions on our platform ThingIT. For example, we use the presence sensor to analyze and output the room and desk usage in real time. We access the data via the OpenAPI from smartengine, which has proven to be a reliable and fast resource"
Dr. Marc Gille Sepehri,
Founder and CEO @Thing-IT
"The cooperation between wtec and pinestack is an important building block in the digital ecosystem of smart buildings. At its core, it is all about capturing data via wtec and storing, editing, and visualizing via pinestack. The smartengine OpenAPI interface ensures fast, secure and trouble-free communication between our systems. This creates smart building tools for users, operators and administrators"
Tim Philip Schröder
"We at aedifion use the BACnet/IP interface of smartengine to mobilize the collected sensor data for additional applications. Among other things: Analytics, control via user interfaces. The integration of smartengine into our cloud platform was easy and plug and play thanks to the BACnet/IP interface"
Dr. Ing. Johannes Fütterer,
“In the ROM laboratory in Hamburg, we measured and simulated the savings potential of the smartengine technology. In addition to the smart, energy-efficient control of the lighting, the smartengine's BacNet interface was used to implement a presence-controlled regulation of heating, cooling, air-conditioning (HVAC) and external blinds. As a result, depending on the type of room, we were able to determine a reduction of up to 35% in energy expenditure and energy costs.”
Dr. Ing. Bruno Lüdemann,
Leiter F&E @Rud. Otto Meyer Technik GmbH & Co. KG
"We, the Sauter-Cumulus Gmbh branch office Düsseldorf, use the BACnet/IP interface of smartengine to connect the wtec lights to our building automation. Currently, we use it to display the energy values to the user. Further use will be the control of the lights via the building automation as a superordinate function, as well as the use of presence detectors or multi-sensors for evaluation purposes. In addition, the use-dependent activation of heating, cooling and, if necessary, ventilation will then be possible. Through our connection to energy generation, significant savings can be achieved for the building. All states and measured values of the wtec system can be displayed and evaluated via the building automation system.
The interconnection of the systems runs without any prob-lems and is stable and easy to implement after the parameters have been adjusted. The cooperation with wtec works very well here"

smartengine Hard- and Software specifications
The smartdirector is responsible for the logical management of up to 40 smartengines and up to 2,000 sensors. The collected sensor data is stored at the director for up to one year. The smartdirector also serves as the communication link between smartengine and 3rd party building systems via an integrated, open API and a BACnet/IP interface for building management systems (BMS).
The smartengine is the workhorse of the smartengine platform. Both power delivery and data communication are delivered over the 48 port, 1.5 RU rack mountable device. The smartengine is designed to deliver fixed current DC power to light fixtures, eliminating the need for any active power conversion components in the plenum. Communication of all sensor data is sent back and aggregated at the engine before being delivered to the smartdirector
smartsensors are the data collection devices that get deployed throughout the built environment. smartsensors collect motion data via a digital passive infrared (DPIR) sensor, light levels through a photocell, and temperature. These sensors collectively allow insight into how spaces are being used, lights to be finely tuned to the ambient light in their immediate area, and inform end users of hot and cold spaces throughout a facility. Power consumption at a per fixture level also allows for measurement and verification data often required to achieve efficient building credits (LEED, BREAM).
