Find Devices on Your Wi-Fi Network

Discover devices and services on a network you own or are authorized to test.

What this does

LAN discovery lists devices and advertised services on the Wi-Fi network GhostESP is currently connected to.

Before you start

On-device steps

  1. Open Menu → WiFi → Scanning while GhostESP is connected.
  2. Choose Scan LAN Devices.
  3. Review the discovered devices and services.

CLI steps

  1. Run scanlocal to discover devices and services.
  2. Run scanarp to list active devices by IP address and MAC vendor.
  3. Run snmpprobe / enumscan to identify SNMP devices and SMB hosts.

LAN scans automatically reuse the most recent ARP sweep results as the host list (with MAC vendor labels) instead of ICMP-pinging every address, which catches Windows hosts that block ping. When no ARP results are available, scans use the actual subnet mask up to /20 rather than assuming /24.

Expected result

GhostESP lists available hostnames, service types, ports, or IP addresses. Results depend on the devices that respond and the network’s isolation settings.

Govee lights and Wake-on-LAN

  • For a supported Govee light, enable LAN Control in the Govee Home app, then open WiFi → Gadgets → Govee Lights → Scan Govee Devices. Select a result to turn it on or off, set brightness, or set an RGB color.
  • To wake a compatible PC, open WiFi → Gadgets → Wake on LAN, enter its MAC address or its live LAN IP, and submit. The PC must have Wake-on-LAN enabled and remain connected to power and the network.

Troubleshooting

  • No devices appear: Confirm GhostESP is connected to the intended network and that client isolation is not enabled.
  • Only some devices appear: Retry after devices are active; not every device advertises services or responds to discovery requests.
  • The connection drops: Reconnect GhostESP, then repeat the discovery scan.
