Overview

My Implementation

I use the SB8200 as my ISP modem to avoid rental fees and to keep my network ready for gigabit‑class plans. It feeds my router directly, and I use the built‑in status page for quick health checks.

Home Assistant Integration

Integration Method: No official SB8200 integration. Community options can monitor cable modem status pages if available.

  • Requirements: Modem status page accessible on your LAN
  • Entities: Signal levels and channel stats (community integration dependent)
  • Setup: Install a community cable modem monitor integration (HACS) and configure device access
  • Notes: Compatibility depends on your modem’s status page HTML

Practical Considerations

  • ISP compatibility: Approved for Xfinity and Cox on the official product page
  • Router required: No Wi‑Fi built in, so you need a separate router or mesh system
  • Performance: Best paired with gigabit‑class plans to justify DOCSIS 3.1
  • Ports: Two 1‑Gigabit Ethernet ports available
