Choosing the Right Dashboard — and Building Something Smarter Together

We’ve been exploring how to make indoor air healthier — and while monitor selection matters, what you do with the data matters even more.
That’s why we built the Hong Kong Online Dashboard: a free, open‑source tool that brings together real‑time AQHI, pollutants, weather, UV, and humidity — all synced by district, all in one place. Every reading is timestamped and sourced, so you know exactly what you’re looking at.
It’s not just a dashboard — it’s a starting point:
- Use it for free.
- Fork it, adapt it, extend it.
- Say hi, star the repo, or buy me a coffee ☕ if it helps you out.
Why this dashboard is different
- Unified view: No more switching between apps — everything’s here.
- Transparency: Every reading is timestamped and sourced.
- Local relevance: Tailored for Hong Kong districts.
- Extendable: Add your own sensor data, traffic, news, or smart home triggers.
- Community‑ready: It’s becoming a hub — not just for clean air, but for connected living.
Monitor selection still matters
As Ethan Brooke’s AirGradient article shows, even “premium” monitors often hide off‑the‑shelf sensors, depend on fragile cloud services, or block access to raw data. He tested 50 devices and found recurring problems: lock‑in, lack of transparency, and poor long‑term reliability.
That’s why our dashboard emphasizes open pathways: you can plug in community sensors, personal monitors, or new feeds without worrying about lock‑in. Choosing the right monitor ensures your dashboard reflects reality, not marketing gloss.
Community use and support
It’s free to use — because clean air and clear information should be table stakes. If it helps:
- Say hi: Share feedback, ideas, or local quirks we should account for.
- Star the repo: It signals interest and keeps the project visible.
- Buy me a coffee: A small boost that funds uptime, sensors, and polish.
Build with us
Want to add your district sensor, a neighborhood alert feed, or a fun visual for the skyline? Let’s co‑create. This is how tools become community infrastructure: open code, honest data, and local pride.
