Aedifion

aedifion GmbH is a Cologne-based PropTech founded in 2017 that operates a vendor-neutral, patented cloud platform for the optimized operation of non-residential buildings. The platform ingests real-time operating data from all building trades via plug-and-play edge devices, applies analytics and AI to detect faults and inefficiencies, and autonomously controls HVAC and building services based on weather forecasts, occupancy and electricity prices - cutting energy use, CO2 emissions and operating costs by up to 40% without structural retrofits. Products span aedifion.io (connectivity and monitoring), aedifion.analytics, aedifion.controls, aedifion.dynamics (demand-side management) and aedifion.smartkit. Developers get a documented HTTP API (OpenAPI 3.0, 208 operations across projects, datapoints, timeseries, analytics, controls, alerts and tasks), an MQTT broker and a Kafka interface for streaming building telemetry. The company serves owners, operators and asset managers of commercial real estate and supports decarbonization, ESG reporting and DGNB, ISO 50001 and GEG certification.

Aedifion publishes 2 APIs on the APIs.io network: HTTP API and MQTT API. Tagged areas include Building Automation, Smart Buildings, Energy Management, Internet of Things, and Real Estate.

The Aedifion catalog on APIs.io includes 2 event-driven AsyncAPI specifications.

Aedifion’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 32 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/aedifion: open an issue to ask a question, or submit a pull request to add artifacts.
