IoT Kits​

Zerynth IoT devices are microcontroller boards equipped with the ATECC608B component, a cryptographic co-processor with hardware-level secure key storage. The devices will be installed to implement machinery and plant monitoring; below are the IT requirements to ensure their operation:

  • UDP outbound connection for DNS resolution on port 53. NOTE: devices can be configured with custom DNS if needed.
  • TCP outbound connection to second-level domain *.zerynth.com on ports 8883, 443, 80.
    • zmqtt.zdm.zerynth.com port 8883 (secure MQTT protocol), for sending data, remote procedure calls, and firmware update management
    • api.zdm.zerynth.com port 443 and firmwares.zdm.zerynth.com port 443 (HTTPS protocol) for downloading firmware update
    • zfs.zdm.zerynth.com port 443 (HTTPS protocol) for uploading files from the device to the cloud and for downloading files from the cloud to the device

NOTE: More than one numeric IP address is associated with the symbolic host names listed above, due to the balancing of incoming traffic on the Zerynth cloud. It is necessary that all IP addresses are allowed on the firewall.

For connection to the Zerynth platform, devices require an Ethernet or WiFi 2.4 GHz connection (WPA2 security levels, WPA2 Enterprise with PEAP authentication) without a captive portal.

Devices can be configured to connect in DHCP or with fixed IP, in the latter case it is necessary to define, for each device, the list of:

  • IP address, e.g. 192.168.1.12
  • Gateway, e.g. 192.168.1.250
  • Mask, e.g. 255.255.255.0
  • DNS optional, default 8.8.8.8

Indicatively, the volume of data traffic is about 1 kByte/minute upload and 100 Bytes/minute download for each IoT device.

Gateways are industrial PCs used for interconnection 4.0 with machinery, test environment for verification of connection requirements, and local development environment with remote access via Zerynth VPN.

In addition to the requirements listed for IoT devices, gateways require:

  • Outbound connection to gateway.zerynth.com endpoint - 195.201.224.239 on port 21194 UDP for remote access via private VPN.
  • Need to be on at all times to be reachable via ssh/vnc for maintenance and testing
  • Need to be connected to the same corporate network as the devices to be reached through it
  • Need to maintain proper configuration of eth ports and related wiring to the network in case of static IPs
