I have looked at
AiMesh whole home mesh wifi system
and the only mention of a cloud service that I found was:
Always-Up-to-Date Protection against Attacks
A step above standard firewalls, the commercial-grade intrusion
prevention system (IPS) performs in-depth scans of inbound and
outbound internet data to block all common attacks. Thanks to Trend
Micro data center on the cloud, this AiProtection feature updates
itself whenever a new patch is available, ensuring your protection is
always up-to-date
My conclusion is that the internet is only used for the purpose
of updating the AiMesh software.
The "AI" label itself seems like a commercial hype, since self-update
does not require artificial intelligence.
