[admin]

This warning indicates that using an underscore (_) in the hostname (kc_a16) might cause issues with certain DHCP or local name services like mDNS. Solution: Rename the hostname to avoid using underscores and use letters, numbers, and hyphens (-) instead. For example:
esphome:
name: kc-a16 # Use a hyphen instead of an underscore
