# Introduction to X2B – Overview of functions

X2B is a powerful **visualization and control software** for building and home automation. The software runs on dedicated hardware and enables the **integration, control and automation** of systems such as **KNX, BACnet, Modbus, LoRa, Philips Hue and Sonos**.

The X2B platform combines various communication protocols and enables uniform operation and automation of devices in a building. It is suitable for both **private smart homes** and **complex commercial building automation systems**.

---

## **Main functions of X2B**

### **1. interfaces - integration of systems**

X2B can communicate with various automation systems:
✔ **KNX (incl. KNX-IP, KNX TP, KNX-RF & KNX-PL)**
✔ **Modbus (TCP )**
✔ **BACnet/IP**
✔ **LoRa & LoRaWAN** **via TTN**
✔ **HTTP & MQTT for IoT devices**
✔ **Philips Hue, Sonos, Netatmo & other Smarthome devices**

These interfaces make it possible to **manage sensors, actuators and other systems centrally**.

---

### **2. channels - manage data points**

A channel is a single **data point** (e.g. temperature, light status or switch status).

- **Reading & writing** values
- **Linking different systems**
- **Logging & visualization** of sensor data

Thanks to the flexible channel structure, data points from different systems can be easily combined with each other.

---

### **3. controls - create control elements**

**User-defined control elements** can be created with Controls.
Examples:
✔ Combine light switches for KNX & Hue
✔ Temperature control with Modbus sensors
✔ Control Sonos speakers

... and many more

Special:

- **Gateway control** connects data points from different systems
- **Logic control** for individual automation

---

### **4. visualization & dashboards**

X2B enables a **customized user interface** with:
✔ **Buttons & sliders**
✔ **Diagrams & graphs for sensor data**
✔ **Interactive dashboards for different users**

Visualization can be carried out via **web browser or remote access**.

---

### **5. automations & scenes**

You can create **your own rules** with **Triggers & Actions**.
Examples:

- **When window open → Heating off**
- **Motion detected → Light on (at night)**
- **Temperature < 18°C → Turn up the heating**

Automations can be time-controlled, sensor-based or manually activated.

---

### **6. user & rights management**

✔ Multiple users with **individual authorizations**
✔ Groups for **filtered access**
✔ Guest mode for restricted use

---

### **7. remote access & remote access**

X2B can be accessed securely **via the Internet**:
✔ **Local IP address (LAN access)**
✔ **Remote URL (`https://<ID>.x2.energy`** )
✔ **Port releases for KNX, Modbus & web interfaces**

With the **X2B Remote Access software**, **local network devices can be controlled worldwide**, e.g. for **ETS remote access to KNX IP interfaces**.
