New multisensor for building automation and the Internet of Things (IoT)

EnOcean's new solar-powered multisensor represents a step change in capability for self-powered wireless sensors, providing monitoring and reporting of five separate parameters from a solar cell, integrated into a single case. The EnOcean STM 550 combines sensors for temperature, humidity, lighting, acceleration and magnetic contact within a single case, offering data for a wide range of applications in digitized buildings and the IoT.

EnOcean, the pioneer of energy harvesting, has developed a new multisensor, the all-round talent among self-powered wireless sensors. In the new original PTM form factor the sensor module supplies data for a wide range of applications in digitized buildings and the IoT. The integrated solar cell generates all the energy required for operation - both for measurement and for data communication. The gathered energy is stored internally to ensure that the sensor will function even when there is little or no light. This means that the self-powered sensor can be used flexibly in buildings. Moreover, it can easily be configured and commissioned via an NFC (Near Field Communication) interface.

EnOcean is constantly creating new developments in the field of battery-free wireless technology as digitization advances through IoT, making buildings intelligent and sustainable. Thanks to energy harvesting, the power generation through movement, light and temperature differences, EnOcean products are both self-powered and maintenance-free and therefore can be used flexibly and exactly where data is needed.

New sensor module in the standardized form factor

The new STM 550 multisensor family combines temperature, humidity, lighting, acceleration and magnetic contact sensors in a small case. The multisensor is available both for the EnOcean wireless standard and for Bluetooth® systems. This makes the sensor particularly attractive for a variety of applications in the IoT and in digitized buildings. For the first time, EnOcean has transferred the original PTM form factor of its proven PTM switch module to sensors, so the multisensor module fits into all common switch frames. Manufacturers of existing switch solutions based on the PTM module therefore only need to develop new front panels adapted to the respective frame design. The new multisensor is also available as Easyfit product, which allows new applications to be implemented quickly. Thanks to the integrated solar cell, the sensor supplies itself with energy independently and stores it for uninterrupted operation over several days with little or no light. It also sends reports on the internal energy level and the amount of light available on the solar cell. As a result, STM 550 operates completely maintenance-free. Being a wireless product, the multisensor can be flexibly installed anywhere in the room. It can also be integrated directly into a wide variety of assets and therefore can be used exactly where the data is needed: on walls, ceilings, windows, doors, furniture, active devices such as air conditioners, towel dispensers and objects such as printers, copiers, medical equipment or vending machines.

"The increasing spread of IoT applications requires more and more data that can be generated maintenance-free and in real time in any place," says Matthias Kassner, Vice President Product Marketing, EnOcean GmbH. "The new EnOcean multisensor supplies exactly this data. Thanks to the widely used original PTM form factor it can be quickly integrated into existing customer designs, enabling innovative sensor solutions to be implemented in the shortest possible time."

Commissioning via NFC

The multisensor has an integrated NFC interface for easy configuration and commissioning. All that is needed is a computer with an NFC reader or an NFC-capable smartphone or tablet. EnOcean's own app "EnOcean Tool" serves as the configuration interface between the multisensor and the smartphone. It can be used to determine important product parameters and to integrate the multisensor into existing systems. The app is available free of charge for iOS and Android.

Kopp expands portfolio with multisensor

Heinrich Kopp GmbH, supplier for innovative and high-quality solutions in the fields of switch systems, mobile personal protection, building automation and e-mobility, already has the new multisensor in use.

"The self-powered multisensor supports our idea of a comprehensive house automation concept outstandingly. Thanks to its flexible use, we can detect a wide range of situations and are able to let corresponding scenarios and reactions of the building automation take place", says Stephan Dörrschuck, CEO of Heinrich Kopp GmbH. "The smooth integration via Bluetooth fits perfectly into our strategy of a simple and intuitive installation. We are pleased that this cooperation has come about."

Eltako implements multisensor into their switch frames

Eltako, one of the leading companies in the development, manufacture and sale of switchgear, power supply units and electronic power meters, has also added the new multisensor to its product portfolio: "The solar multisensor is the perfect addition to our extensive product range", Ulrich Horst Ziegler, CEO of Eltako, states. "Due to the original PTM form factor, we can easily integrate the sensor into our switch designs and thus provide the end user with an unprecedented range of functions. Additionally, we have also developed a mini housing for the wireless mini-multisensor FMMS44. We are very excited about this new sensor all-rounder."

EnOcean Energy Harvesting: Battery-free PTM switch module with NFC and security

EnOcean has added an NFC (Near Field Communication) interface and safety functions to its recognized PTM switch module.

EnOcean, the world's leading developer of energy harvesting wireless technology, has extended the latest generation of its proven PTM 215 switch module for the EnOcean wireless standard with an integrated NFC interface and state-of-the-art safety functions. This means that in addition to the proven logic "press button", battery-free switches can now also be operated automatically with NFC readers and NFC-capable smartphones or tablets. At the same time individual settings are possible and the safety mechanisms can be activated and confirmed with EnOcean's own "EnOcean Tool" app. The module does not have to be removed from the switch housing, so even switches that are already installed can be configured with the app. The successful original PTM form factor is retained by the innovations, so that the new PTM module continues to fit into common switch designs for a battery-free control of lights, shutters and consumers in building automation and the smart home.

The PTM 21x switch module from EnOcean is at the heart of every battery-free switch and has become established as the industry standard. The latest generation of the PTM 215 switch module for the EnOcean wireless standard in 868 MHz now additionally integrates an NFC interface and meets the latest EnOcean Alliance safety standards. The NFC interface provides additional setting options, allowing the devices to be integrated easily and automatically into existing systems. NFC devices can be easily commissioned via NFC readers and NFC-enabled smartphones or tablets. Inside, the switch module still combines the ECO 200 electromechanical energy converter with an efficient radio module for an optimum energy yield at each keystroke and maximum transmission power. The switch module with NFC has the same original PTM form factor as all PTM switch modules from EnOcean, so it fits into all common switch frames.

Commissioning via NFC

Commissioning via the NFC interface with read and write function enables a variety of applications. A suitable app such as "EnOcean Tool" should have been installed on the NFC reader beforehand. The security mode can be easily activated using this type of commissioning. With the help of NFC commissioning, the respective project can be digitally documented and all relevant data for encryption can be stored in a project database. Commissioning via the NFC interface also allows a clear product identification. As an optional function, the product ID can be inscribed with all characteristics such as switch design and function. With this product ID, the installer knows in advance whether the switch module has been preconfigured for single or double rocker switches. For remote commissioning, the app also receives all necessary information via the NFC interface. In addition, the rolling code is sent as a sequence code with each telegram, as is common with other protocols, which means that the initial teach-in telegram is no longer necessary.

"The integration of an NFC interface now makes our proven PTM switch module even more attractive for installers and OEMs, thanks to the very easy commissioning of the modules", says Marián Hönsch, Product Manager at EnOcean. "The Commissioning of self-powered sensor and switch modules via NFC offers a simple solution for implementing a sensor system in a building as easily as possible and adapting it to specific requirements. That's why we at EnOcean see great potential in NFC. We are working closely with the EnOcean Alliance to ensure that in future NFC will be used extensively in products and solutions of the EnOcean eco-system.”

Data security with NFC

A high level of data protection is guaranteed when exchanging data via NFC. One of the reasons for this is that NFC device and NFC reader must not be more than two centimetres apart. The fact that the device keys for EnOcean radio communication via NFC can be changed but not read also contributes to increased data protection. This complies with the current security standards of the EnOcean Alliance. In addition, a desynchronisation of transmitter and receiver is impossible because the rolling code, a continuously incrementing counter for concealment and authentication, is sent with each transmission. In addition, the new PTM switch module is 100 % backwards compatible with the functional modes of the previous generation of the PTM 210/215.

Configuring NFC devices from EnOcean with "EnOcean Tool”

For easy configuration and commissioning of EnOcean NFC devices like the next-generation PTM module, EnOcean has developed its own app that is available free of charge for iOS and Android. Installed on a smartphone, "EnOcean Tool" can be used to determine all product parameters and the devices can be easily integrated into existing systems. This makes the app particularly interesting for OEM’s and installers. In addition, all product information such as device recognition or product ID can be read out. A secure access to the data in the NFC interface is guaranteed with a user-defined PIN code.
