Ping (ICMP)


The 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.

Configuration

To use this presence detection in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry

      hostone: 192.168.2.10

Configuration Variables
