There is currently support for the following device types within Home Assistant:
ping binary sensor platform allows you to use
ping to send ICMP echo requests. This way you can check if a given host is online and determine the round trip times from your Home Assistant instance to that system.
To use this sensor in your installation, add the following to your
# Example configuration.yaml entry binary_sensor: - platform: ping host: 192.168.0.1
The sensor exposes the different round trip times values measured by
ping as attributes:
round trip time mdev
round trip time avg
round trip time min
round trip time max
The default polling interval is 5 minutes. As many components based on the entity class, it is possible to overwrite this scan interval by specifying a
scan_interval configuration key (value in seconds). In the example below we setup the
ping binary sensor to poll the devices every 30 seconds.
# Example configuration.yaml entry to ping host 192.168.0.1 with 2 packets every 30 seconds. binary_sensor: - platform: ping host: 192.168.0.1 count: 2 scan_interval: 30
When run on Windows systems, the round trip time attributes are rounded to the nearest millisecond and the mdev value is unavailable.
ping device tracker platform offers presence detection by using
ping to send ICMP echo requests. This can be useful when devices are running a firewall and are blocking UDP or TCP packets but responding to ICMP requests (like Android phones). This tracker doesn’t need to know the MAC address since the host can be on a different subnet. This makes this an option to detect hosts on a different subnet when
nmap or other solutions don’t work since
arp doesn’t work.
Please keep in mind that modern smart phones will usually turn off WiFi when they are idle. Simple trackers like this may not be reliable on their own.
To use this presence detection in your installation, add the following to your
# Example configuration.yaml entry device_tracker: - platform: ping hosts: hostone: 192.168.2.10
See the device tracker component page for instructions how to configure the people to be tracked.
