What it does

Open-FDD is an open-source, knowledge-graph automated fault detection and diagnostics (AFDD) platform for HVAC systems that runs on-prem—no vendor lock-in, no data loss, no fees. It turns building telemetry into actionable fault insights using a rule-based cookbook for energy savings (~8–9%). With Open Claw, engineers can deploy AI-powered modeling, monitoring, and optimization on the building knowledge graph—capabilities not available in today’s proprietary, high-fee smart building software.

I built a frontpage for personal blogs▲783
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
