What I Build
Open source integrations that surface hidden data and turn it into something useful — dashboards, automations, and AI-ready pipelines.
Home Assistant Integrations
- 8311-ha-bridge — XGS-PON fiber ONU monitoring (found a 160°F overheating modem with this)
- web888-ha-bridge — Web-888 SDR receiver monitoring
- pskr-ha-bridge — PSK Reporter ham radio propagation
- wspr-ha-bridge — WSPR weak-signal propagation data
- ntopng-ha-bridge — Network traffic analysis
- metermon-ha — Dockerized RTL-SDR utility meter monitoring with MQTT Discovery
- ha-zoom-automation — Zoom presence detection (powers my "On The Air" sign)
MCP Servers (AI Assistants)
- your-spotify-mcp — Unlimited Spotify listening history for Claude, Gemini, and other AI tools
Why Sponsor?
20+ years in telecom taught me: you can't fix what you can't measure. Every one of these projects exists because some piece of hardware or API had useful data locked behind a wall.
Your sponsorship funds development time, new hardware to integrate, and keeping everything maintained as platforms evolve. Most people unwind with Netflix. I unwind with a soldering iron.
