IoT Kit Components

The azeti IoT Kit includes the following components:

  • Unipi Neuron S103 IoT Gateway. Main characteristics:
    • Industry grade Raspberry Pi 3 based gateway
    • 4 Digital Inputs
    • 4 Digital Ouptuts
    • 1 Analogue Input
    • 1 Analogue Output
    • 1 1wire port
    • Includes an 8GB SD Card with the OS and Azeti SiteController already installed
    • For more information check the Unipi documentation here
  • Electrical Components:
    • Power Supply: Meanwell DR-15-24.
      • Input Voltage 85 VAC to 264 VAC, 120 VDC to 370 VDC
      • Output Voltage: 24 VDC
      • Output Current (max): 0.63 A
      • Maximum Power: 15 W
    • Main Breaker (controls the power to the whole kit): Siemens 5S
      • Rated Operational Voltage: 250 VAC
      • Rated Current: 10 A
    • Sensor Breaker (controls the power to the sensors)
      • Rated Operational Voltage: 250 VAC
      • Rated Current: 16 A
    • Relay Finder Controlled by the Unipi Digital Output (DO1) is connected to the AC power of the kit and to the AC output power socket.
      • Coil Voltage: 24V DC
      • Contact Voltage: 250VAC
      • Contact Current: 16 A
  • Sensors and Outputs
    • Inepro Smart Energy Meter Pro1 Modbus: Smart Meter that reads the overall power consumption of all the elements included in the kit, plus whatever is connected to the AC power output. It also gives voltage, current and frequency readings.
      • Nominal voltage (Un) 230V AC
      • Operational voltage 195-253VAC

      • Basic current (Ib) 5A

      • Maximum rated current (Imax) 45A

      • Operational current range 0.4%Ib-Imax

      • Overcurrent withstand 30 Imax for 0.01s

      • Operational frequency range 50Hz ±10%

      • Internal power consumption ≤2W/Phase - ≤10VA/Phase

      • For more information check the manual here
    • Autosen AC004 – Capacitive sensor. Capacitive sensor that sends a signal whenever detects some object near this upper side (green). Connected to a Digital Input of the Unipi (DI2)
    • Magnetic Door Contact: Mounted on the enclosure, detects when the lid is opened or closed. Connect to a Digital Input of the Unipi (DI1)
    • LED: Mounted on the top side of the enclosure, is controlled by a Digital Output of the Unipi (DO2). The default behavior is that the LED is turned on whenever the lid is opened.
    • 1-Wire Temperature sensor DS18B20
      • Measures Temperatures from -55°C to +125°C (-67°F to +257°F)

      • ±0.5°C Accuracy from -10°C to +85°C

Basic Setup procedure

To setup the IoT kit follow this steps:

  1. Connect the provided PC Power cable to the AC Power Input on the top side.

    Make sure to connect to the AC Power Input and NOT to the AC Power Output socket (see previous pictures)

  2. Connect the Ethernet Network Cable to the Ethernet Input port on the top side.

    The Ethernet port is configured to work with DHCP. If no DHCP is enabled the default IP will be The IoT Gateway also has a wlan interface. To learn how to configured it go to the WLAN Configuration section in this document.

  3. Switch ON the Main Breaker
  4. Switch ON the Sensors Breaker

After this the IoT kit will be already working. To start using the kit:

  1. Retrieve your password →, an e-mail will be sent to you with your password. Use the same email that was used on the store purchase. Further accounts can be created once logged in to the cloud.
  2. Login to the IoT Cloud →

Other Information

Accessing the console

The IoT Gateway runs as OS Debian Linux. To access the console follow one of the following methods

  • SSH to the device IP. If no DHCP is present in the network the IP will be 
  • Connect a screen to the right side HDMI port, and a keyboard to one of the USB ports. 

In both cases the user is always pi, and the password will be provided to you with the welcome letter.

WLAN Configuration

To configure the wireless LAN of the IoT gateway follow this steps:

  1. Access the console
  2. Edit the file /etc/wpa_supplicant/wpa_supplicant.conf

    sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
  3. Write the SSID and password of the WLAN network

    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
  4. Restart the wlan interface

    pi@UniPi-Test:~ $ sudo ifdown wlan0
    pi@UniPi-Test:~ $ sudo ifup wlan0
  5. Check that the wlan0 interface has an IP (might take a few seconds)

    pi@UniPi-Test:~ $ ifconfig
