The invention relates to a firmware over-the-air (FOTA) method for updating building services, in particular lighting technology installations, comprising multiple devices which are connected to a server as a mesh network, wherein the method comprises the following steps: storing a firmware update image sent by the server in a respective memory of each device, and triggering the copying of the firmware update from the memory to an internal memory of a microcontroller of each of the devices by means of a trigger command issued by the server, wherein, within a predefined time period (timeout) after the trigger command is issued, the server uses feedback from the devices to check whether each device has received the firmware update image and the trigger command, and wherein the copying does not take place until after the predefined time period has elapsed.

Firmware over-the-air (FOTA) update for building services

A communication module for a building technology device, especially a luminaire, is provided, wherein the communication module is configured to be connectable to an IoT-network and a communication bus, and being configured for a bi-directional communication on the IoT-network and the communication bus, wherein the communication module is configured to convert communication data between the communication bus and the IoT-network.

IoT communication module for a building technology device, bus device, a building technology device for IoT-networks, building technology communication system and building technology management system

The invention refers to a communication module arranged to support execution of commissioning of one or more installed devices and configured to transmit, according to Thread network protocol, via multiple channels a connectivity verification message arranged to initiate an execution of a predetermined activity by the one or more installed devices. Present invention concerns a commissioning device, transmitting the connectivity verification message to the one or more installed devices via the communication module, and installed devices, each installed device monitoring received messages, determining whether or not a received message is the connectivity verification message, determining whether or not a signal strength of the received message is above a predetermined threshold, if the received message is a connectivity verification message and if the signal strength of the received message is above the predetermined threshold, executing the predetermined activity. Further, the invention concerns a managing device supporting the execution of said commissioning.

Commissioning of one or more installed devices of a lighting system

The present invention is in the field of Power over Ethernet (PoE) systems comprising a power supply module and an operation module with an emergency operation mode for operating lighting means, wherein the power supply module supplies a supply voltage via a data cable to the operation module. Especially, the present invention relates to power supply modules, preferably Power Sourcing Equipments (PSE) according to the PoE standard; operation modules with an emergency operation mode, preferably Powered devices (PD) according to the PoE standard; PoE systems, comprising such power supply modules and operation modules; and a detection method for detecting whether an operation module is arranged for operating lighting means in an emergency operation mode as well as an emergency operation mode triggering method for triggering an operation module to operate lighting means in an emergency operation mode.

Emergency signaling for power over ethernet systems

A lighting control system includes a master unit and a plurality of slave units. The slave units are respectively designed to consume power by operating lighting means, are supplied by a common power supply unit, can be provided with commands from the master unit, and are respectively provided with a control unit which modulates the power consumption of the associated slave unit according to a defined protocol. The master unit is designed to measure the power consumed by all slave units.
