## **MQTT Payload Description – RFTC3**

This manual describes how to interact with the RFTC3 (Room Fan Coil Thermostat Controller) via MQTT using the iNELS system.

### **MQTT Topics Overview**

MQTT topics are categorized into three main types:

#### 1. **Connected**

Indicates the **online/offline status** of the gateway (GW) or connected devices.

**Topic format:**

```
inels/connected/<MAC_ADDRESS>/<DEVICE_TYPE>
```

**Example:**

```
inels/connected/2C6A6F105BB2/gw
```

***

#### 2. **Status**

Displays the **current state** of the gateway or RFTC3 device, including parameters such as temperature, occupancy, fan state, etc.

**Topic format:**

```
inels/status/<MAC_ADDRESS>/<DEVICE_TYPE>
```

**Example:**

```
inels/status/2C6A6F105BB2/RFTC
```

**Typical status payload:**

SetPoint : Comfort, Standby, Economy, BuildProtection\
CurrentTemp : "24.01",\
FanState : "AUTO",\
Economy : "0.00",\
RoomOccu : "0.00",\
Window : "0.00",\
MUR : "0.00",\
DND : "1.00",\
AktSetTemp : "28.00",\
Butler : "0.00"

#### 3. **Set**

Used to **send control commands** to the device.

**Topic format:**

```
inels/set/<MAC_ADDRESS>/RFTC/<PARAMETER>
```

**All payloads must be sent as strings.**

***

### **Note on MAC Address and Device Types**

Each iNELS device is uniquely identified by its **MAC address** and **device type** (e.g., `gw`, `RFTC`, `device type`).\
Refer to the \[MQTT Device Manual] for full address mappings and descriptions.

### **Example – Setting DND ON**

**Topic:**

```
inels/set/2C6A6F105BB2/RFTC/DND
