In the era of the Internet of Things (IoT) and digitalization, the demand for smart buildings is constantly growing. However, many existing buildings are equipped with obsolete automation systems that do not support modern communication protocols and advanced functionalities. Retrofitting, or the modernization of these systems, represents an effective solution to transform obsolete buildings into smart buildings, improving energy efficiency, comfort, and space management.

### Advantages of Retrofitting

Retrofitting offers numerous advantages, including:

- **Improved energy efficiency**: the integration of advanced sensors and control systems optimizes energy consumption, reducing costs and environmental impact.
- **Increased comfort**: the ability to monitor and control environmental conditions in real time, such as temperature, humidity, and air quality, ensures a more comfortable working or living environment.
- **Centralized management**: retrofitting systems allow for centralized management of facilities, simplifying monitoring and maintenance.
- **Integration with standard protocols**: the use of standard protocols, such as BACnet/IP, facilitates integration with other systems and devices, ensuring interoperability.

### Key Products for Retrofitting

For effective retrofitting, it is essential to use reliable and versatile products that support the main communication protocols. In this context, LOYTEC and Milesight products represent an excellent choice:

- **LOYTEC [LOY-SPE2](/en/ethernet-ip/loy-spe2)**: this versatile device allows you to extend the Ethernet connection over a simple copper twisted pair, thus making it possible to reach un-wired or unreachable areas with a direct Ethernet cable. The device is very interesting because it allows, for example, to recover old LONWORKS lines and use them to make them Ethernet data lines.

- **Milesight [UG65](/en/lorawan/ug65-semi-industrial-lorawan-gateway-with-external-antenna)**: this LoRaWAN gateway with native BACnet/IP support allows for easy integration of wireless sensors into the automation system. Its ability to natively support the BACnet/IP protocol makes it ideal for integration with existing building automation systems.

- **Milesight Sensors [AM102](/en/temperatura-1/am102-2-in-1-lorawan-iaq-sensor), [AM103](/en/temperatura-1/am103-lorawan-environmental-monitoring-sensor) and [WT201](/en/milesight-lorawan/wt201-lorawan-thermostat)**: these wireless sensors, which measure temperature, humidity, air quality, and other environmental parameters, can be easily integrated into the system via the UG65 gateway. Their LoRaWAN technology ensures reliable and low-power communication.

### Simple Implementation and Benefits

The combined use of these products significantly simplifies the retrofitting process, allowing for the rapid and efficient transformation of an obsolete system into a smart one. Communication based on standard protocols ensures interoperability and scalability of the system, paving the way for future expansions and integrations.

In conclusion, retrofitting in building automation represents a strategic investment to improve the efficiency, comfort, and management of buildings. **LOYTEC** and **Milesight** products, with their support for standard protocols and ease of integration, offer an ideal solution for transforming obsolete buildings into cutting-edge smart buildings.
