As the home router uses DHCP, the IP addresses of the devices on the network often change.
To find devices on the network that have ssh open on port 22 you can use:
sudo nmap -sS -p 22 [Base IP Address]/24
where [Base IP Address] is often 192.168.1.0 for most routers and 10.0.1.0 for Apple routers.
