Wireless switches with integrated energy harvesters from EnOcean have been successful in building installation technology for 15 years. The wireless method developed by EnOcean itself, which has since been standardized as ISO/IEC 14543-3-1X and requires very little energy to transmit its data, has also contributed to this success. Thanks to radio transmission in the license-free 868 MHz or 915 MHz range, a considerable range of around 30 m is achieved in buildings despite the tight energy budget.

With the addition of energy-saving operating modes - Bluetooth Low Energy (BLE) and ZigBee Pro - to the Bluetooth and ZigBee wireless standards, they now also allow operation via energy harvesting. This opens up further application possibilities for EnOcean energy harvesters and new applications in combination with Bluetooth end devices and ZigBee networks. The EnOcean wireless switch module (PTM 21x) - suitable for light switches - was followed by the 2.4 GHz version for ZigBee (PTM 215 ZE) and now also the PTM 215B version for BLE, also with 2.4 GHz. All with the same electrodynamic energy converter (ECO 200) and in the same housing, so that the existing switch series can be used for building installations. Only the radio transmitter has been adapted. This is EnOcean's response to developments in the lighting market: in addition to ZigBee, luminaire manufacturers are increasingly using Bluetooth Low Energy for switching and control.

With the expansion of the product range to include versions for other wireless methods such as ZigBee and Bluetooth, the naming of the self-developed wireless method as the EnOcean wireless standard after the company is proving to be unfavorable. A wireless switch from EnOcean that communicates via Bluetooth or ZigBee is unfortunately not compatible with EnOcean wireless. Professional users, installers and end customers would quickly become confused and it would be difficult to clearly distinguish it from the wireless standard of the same name. To avoid confusion with EnOcean wireless technology, EnOcean is renaming its product range "Dolphin" and adding the slogan "Self-powered IoT by EnOcean" to the new name. The new product name is intended to enable separation from the EnOcean wireless process, so that in future the energy harvesters can be used with wireless transmitters compatible with other wireless standards in switches and sensors. The switch modules for ZigBee and BLE are to be followed by solar-powered sensors, e.g. a door and window sensor, a temperature/humidity sensor and a light sensor.
