ambiquality.org is no longer online
Ambiquality — an Indoor Environmental Quality (IEQ) monitoring platform built at VŠE Prague as a bachelor thesis by Vilém Charwot — has been taken offline.
Why
The platform ran a full microservice stack (six .NET 10 services, PostgreSQL/TimescaleDB, Redis, ingress proxy, object storage) around the clock, collecting measurements from a small network of sensor devices (CO2, temperature, humidity, particulate matter, VOCs, acoustics, light).
The recurring infrastructure costs of keeping this stack running — databases, compute, storage for growing measurement archives, and the public-facing open-data APIs — outweighed the usage of the platform. It is a thesis/hobby project, not a funded service, so the decision was made to stop it rather than raise costs.
What it did
- Collected sensor measurements of indoor environmental parameters in real time
- Published them as open data (JSON / CSV / JSON-LD, DCAT-AP 3.0 catalogues)
- Exposed a read-only public API and monthly downloadable measurement archives
What was preserved
The source code, architecture documentation and sensor firmware remain available as open-source repositories — the knowledge lives on even if the public service no longer does.
