Most wifi-accesspoints (WAP) and wifi-routers (WRT) support the Simple Network Management Protocol (SNMP).
This is a standardized method for monitoring/manageing network connected devices. SNMP uses a tree-like
hierarchy where each node is an object. Many of these objects contain (live) lists of insances and metrics,
like network interfaces, disks, and wifi registrations.
This component uses python-pysnmp.
```yaml
# Example configuration.yaml entry
device_tracker:
platform: snmp
hosts: 192.168.1.1
community: public
baseoid: 1.3.6.1.4.1.14988.1.1.1.2.1.1
```
`community` is the SNMP community which is configured in the WAP/WRT. Most devices have a default
community set to to `public` with read-only permission (which is sufficient). This parameter is mandatory
`baseoid` is the OID prefix where wireless client registrations can be found, usually vendor specific.
It's advised to use the numerical notation. To find this base OID, check vendor documentation or check
the MIB file for your device.
See the [device tracker component page](/components/device_tracker.html) for instructions how to
configure the people to be tracked.
