Discover the role of Bluetooth Low Energy (BLE) in Smart Home, the latest trends, applications and the importance of standards such as Matter.
“Digitalization is not an IT project—it is a business strategy.”
– Björn Groenewold, Managing Director, Groenewold IT Solutions
> Key Takeaway: Bluetooth Low Energy (BLE) is ideal for smart home devices like sensors, door locks, and lighting controls thanks to minimal power consumption.
Compared to WiFi and Zigbee, BLE excels with easy pairing, low hardware costs, and native smartphone support — with limitations in range and data throughput.

BLE im Smart Home: Trends and potentials for the German market
Short: The intelligent home, once a distant vision of the future, is today a reality for many people.
The intelligent home, once a distant vision of the future, is today a reality for many people. The control of light, heating and security via smartphone is increasingly part of everyday life.
While technologies such as Wi-Fi and Zigbee have dominated the market for a long time, Bluetooth Low Energy (BLE) plays an increasingly important role in networking home appliances.
Thanks to its extremely low energy consumption and direct connection to each smartphone, BLE opens up new, exciting possibilities for manufacturers and consumers on the German market.
Why BLE in Smart Home? The advantages at a glance
Short: Compared to other radio standards, BLE offers some key advantages for use in Smart Home:
Compared to other radio standards, BLE offers some key advantages for use in Smart Home:
Energy efficiency:** Battery operated sensors (e.g. for window contacts or temperature) can spend years without battery change with BLE.
Direct smartphone connection: Every modern smartphone has integrated BLE. There is no need for a separate bridge or central hub to control a device directly. This significantly reduces the entry barriers for consumers.
Simplified commissioning: The setup of new devices is often uncomplicated and directly possible via the manufacturer's app without having to deal with complex network configurations.
Good hardware: BLE chipsets are inexpensive, which allows cost-effective devices to be manufactured.
Typical applications of BLE in intelligent home
Short: The possibilities for use are diverse and constantly grow:
The possibilities for use are diverse and constantly grow:
Intelligent lighting: Individual lamps and bulbs (Smart Bulbs) can be dimmed directly by BLE, changed color or integrated into light scenes.
Heating control: Smart thermostats for radiators communicate via BLE with the smartphone or a central control unit to efficiently regulate room temperature and save heating costs.
Safety sensors: Battery operated door and window contacts, motion detectors or smoke detectors that send a warning to the smartphone during an event.
Smart door locks: Allow the door to be opened by app without requiring a physical key. The low latency of BLE ensures a quick reaction.
Household equipment: From the coffee machine that can be started by app, to the electric toothbrush that analyzes cleaning behavior – BLE also connects small everyday devices.
The Game Changer: Matter and the Role of BLE
Short: One of the biggest challenges in the smart home has been the lack of compatibility between the two
