Tips to Ensure a Successful Connection

  • If your network has restrictive filtering, whitelist your SmartBox's MAC address. Contact support to find your MAC address.
  • Your SmartBox needs to be able to connect to Cloudflare's DNS servers (1.1.1.1, 1.0.0.1).
  • Your SmartBox needs to be able to contact 4 services running on different subdomains of keycafe.com (subdomain.keycafe.com):
Subdomain Port Service
push 500 Push notifications
monitor 443 Device monitoring
ota 443 Over-the-air updates
www 443 General functionality

IP Address Whitelisting

The IP addresses used by Keycafe for cloud services are subject to change, so we recommend not relying on a static whitelist.
