If this is connecting to telnet, expect may be your best option, but if you're using ssh, you could use keys and avoid having to use expect at all while making your scripts far simpler in the bargain.
If it doesn't work in crontab, that's probably a problem with your environment as per our FAQ.

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)
NAME
ssh-keysign -- ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication.
ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
EnableSSHKeysign to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_ecdsa_key
/etc/ssh/ssh_host_ed25519_key
/etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host-
based authentication is used.
/etc/ssh/ssh_host_dsa_key-cert.pub
/etc/ssh/ssh_host_ecdsa_key-cert.pub
/etc/ssh/ssh_host_ed25519_key-cert.pub
/etc/ssh/ssh_host_rsa_key-cert.pub
If these files exist they are assumed to contain public certificate information corresponding with the private keys above.
SEE ALSO
ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)
HISTORY
ssh-keysign first appeared in OpenBSD 3.2.
