I’m running hassio on a pi3. Every time after using the nmap_tracker HA becomes unavailable.
Both web and ssh interfaces are timing out. Any suggestions?
Last time my solution was reinstalling from scratch, but I’d rather troubleshoot it.
Are you overloading the NIC on the pi?
Any suggestions on how to check that or even better prevent it 
That all depends on what you’re using on your nmap command.
Very basic config:
device_tracker:
- platform: nmap_tracker
hosts: 192.168.2.0/24
