Network Setup - Grillo One

The Grillo One supports both WiFi and Ethernet connectivity. This guide covers how to configure each option.

Connectivity options

Priority	Method	Best for	Requirements
1st	Ethernet	Maximum reliability	Network cable, available port, DHCP
2nd	WiFi	Flexible placement	2.4 GHz network, SSID & password

Connection priority

The Grillo One automatically prioritizes Ethernet over WiFi. If an Ethernet cable is connected at boot, the device will use Ethernet exclusively. WiFi is only used when no Ethernet connection is detected.

Option 1: WiFi setup

Requirements

• 2.4 GHz WiFi network (5 GHz is not supported)
• Network name (SSID) and password
• Smartphone or computer for configuration

WiFi setup steps

1. Power on the sensor (without Ethernet connected)

   • Connect power adapter to the sensor
   • The device checks for Ethernet for about 5 seconds
   • If no Ethernet is found, it enters provisioning mode
   • Network LED will pulse blue indicating setup mode

2. Connect to sensor's hotspot

   • On your phone or computer, look for a WiFi network named GrilloOne-XXXX
   • (XXXX = last 4 characters of the device's MAC address)
   • Connect to this network (no password required)

3. Open configuration portal

   • A captive portal should open automatically
   • If not, open a browser and navigate to http://192.168.4.1

4. Select your WiFi network

   • Available networks are displayed with signal strength indicators
   • Select your network from the list
   • For hidden networks, you can enter the SSID manually
   • Enter your WiFi password

5. Complete setup

   • The sensor validates your credentials and restarts
   • Credentials are saved permanently on the device
   • Network LED turns green when successfully connected
   • The sensor's hotspot will no longer be visible

WiFi troubleshooting

Issue	Solution
Network not listed	Ensure 2.4 GHz network; move closer to router
Connection fails	Verify password; check for special characters
Sensor won't enter setup mode	Power cycle via USB-C cable

Option 2: Ethernet setup

Requirements

• Ethernet cable (included in box)
• Available port on router/switch
• DHCP enabled on network (default for most networks)

Ethernet setup steps

1. Connect Ethernet cable

   • Plug one end into the sensor's Ethernet port
   • Plug the other end into your router or network switch

2. Connect power

   • Connect the power adapter to the sensor
   • The sensor will automatically obtain an IP address via DHCP

3. Verify connection

   • LED should indicate successful connection
   • The sensor will appear on your network

DHCP required

The Grillo One requires DHCP for automatic IP assignment. Static IP configuration is not currently supported. If your network requires static IP addresses, contact your network administrator about setting up a DHCP reservation for the sensor's MAC address.

Network requirements

Firewall and ports

The Grillo One needs outbound internet access:

Purpose	Protocol	Port	Direction
Sensor data & status	UDP	5683, 5684	Outbound
Time synchronization	UDP	123 (NTP)	Outbound
Firmware updates	TCP	443 (HTTPS)	Outbound

note

No inbound ports need to be opened. All connections are initiated by the sensor.

Bandwidth requirements

• Minimum: 100 Kbps upload
• Recommended: 1 Mbps upload
• Data usage: Approximately TBD GB/month

Network restrictions

If your network has restrictions (corporate, university), provide your IT department with these requirements:

• UDP ports 5683, 5684 - Outbound for sensor data
• UDP port 123 - Outbound for NTP time sync
• TCP port 443 - Outbound for firmware updates
• DHCP - Required for IP assignment
• DNS - Required to resolve hostnames

LED status indicators

The Network LED indicates connection status:

LED State	Meaning
Blue pulse	Connecting or in provisioning mode
Green	Connected to network
Yellow	Warning (check connection)
Red	Connection error

Verifying connectivity

After network setup:

1. Check the LED shows "connected" status
2. Log into Grillo Cloud
3. Navigate to your network's sensor list
4. Look for your sensor (may take a few minutes to appear)

Switching between WiFi and Ethernet

To change connectivity method:

1. WiFi to Ethernet: Simply plug in Ethernet cable; sensor will prefer wired connection
2. Ethernet to WiFi: Unplug Ethernet cable; sensor will use configured WiFi

Next steps

Once connected to the network:

1. Provision the sensor to Grillo Cloud
