Lansweeper can pull data from any device that has any of the following protocols enabled: FTP, HTTP, HTTPS, JetDirect, MOB (Managed Object Browser), SIP, SMTP, SNMP (SNMPv1, SNMPv2 or SNMPv3), SSH, Telnet or WMI. Most devices support SNMP by default. I don't have any Meraki devices to test with, but your device documentation should provide more information on which protocols can be enabled on the device. You can use Devicetester, documented
here, to test protocol access to a device and scan a network device by following the instructions in
this knowledge base article.
