What is docsight?

DOCSight is a Python-based Docker app that monitors your DOCSIS cable modem, gateway, or router—like AVM FritzBox models—for signal health, power levels, SNR, and errors across DOCSIS 3.0/3.1 channels. It builds a timeline of trends via interactive charts on a local web dashboard, spotting issues like uncorrectable errors or modulation drops that cause slow DOCSIS cable internet. When your ISP claims "everything's fine," it generates PDF reports and editable complaint letters with DIN/DOCSIS reference thresholds to prove otherwise.

Why is it gaining traction?

It stands out with one-command Docker deploys, a browser setup wizard (no env files), and zero-cloud privacy—your DOCSIS cable device data stays local. Users get automatic health assessments (good/marginal/poor), Speedtest Tracker charts, ThinkBroadband BQM galleries, and MQTT auto-discovery for Home Assistant integration. Multi-language UI (EN/DE/FR/ES), light/dark modes, and bookmarkable views like #trends make it dead simple for ongoing cable diagnostics.

Who should use this?

Homeowners on DOCSIS cable internet (Vodafone Kabel, Comcast, Virgin Media) battling flaky speeds or dropouts, especially with DOCSIS cable modem 3.1 routers. Home Assistant tinkerers wanting per-channel sensors for cable health dashboards. Self-hosters on Synology NAS or servers needing a cable tester alternative without subscriptions.

Verdict

Grab it if you're on coax cable and tired of ISP runarounds—polished docs and Docker ease make setup trivial despite 37 stars and 1.0% credibility score. Still early-stage with a roadmap for modulation alerts and multi-modem drivers, but MIT-licensed and production-ready for personal use today.
