EnOcean to bring Bluetooth LE into energy-harvested operation

October 11, 2016 // By Graham Prophet
EnOcean, developer of energy-harvesting wireless technology, ha sannounced its first energy-harvesting wireless modules for 2.4 GHz BLE (Bluetooth Low Energy) systems. The new modules complement the existing EnOcean wireless technology in the sub-1 GHz band and ZigBee wireless products in the 2.4 GHz frequency band.

The first product in the EnOcean 2.4 GHz BLE portfolio is the batteryless PTM 215B switch module, which also comes with an NFC function for pairing and set-up, making it easier to train and configure the switch. The PTM 215B is based on the established form factor of the PTM 21x module, invented by EnOcean, and can be integrated into a large number of existing switch designs. The switch is also available as a white label end product. EnOcean aims to enable product manufacturers to develop reliable and self-powered solutions on the 2.4 GHz frequency band for use in smart homes and modern light control all over the world.


Manufacturers of BLE-based systems for the 2.4 GHz band can now incorporate energy harvesting technology from EnOcean into their portfolios and develop batteryless, room-based wireless controllers. If they choose to use the standardized PTM 21x form factor, switch manufacturers can integrate the new 2.4 GHz module into their existing product ranges and use maintenance-free BLE systems that produce energy from motion.

"By adding a BLE-based wireless module to our portfolio, we have taken another important step toward fully networking devices in the Internet of Things (IoT)," explains Wald Siskens, CEO of EnOcean.


The radio-based PTM 215B switch can be trained through direct contact with NFC-capable devices without any manual actuation. A number of parameters can also be configured automatically, permitting, for example, protocol data to be modified or additional information to be transmitted, such as group assignments. New devices can thus be integrated into existing systems, substantially reducing their susceptibility to faults.


In addition to the radio-based switch module, the 2.4 GHz BLE portfolio from EnOcean also includes white label end products: energy harvesting wireless single-rocker (ESRP) and dual rocker (EDRP) switches for the American market. Solar-based sensor modules will be added to the switch module in 2017, including a door and window sensor, a temperature/moisture sensor and
