Landis+Gyr

Landis+Gyr Group AG is a 130-year-old energy technology company that builds the smart electricity, gas and water meters, the RF-mesh and cellular networks, and the head-end, meter-data-management and grid-analytics software that utilities run advanced metering infrastructure on. It is incorporated in Cham, Switzerland and listed on the SIX Swiss Exchange, but after divesting its EMEA business to AURELIUS in March 2026 its centre of gravity — and its Americas headquarters and much of its executive team — sits in Alpharetta, Georgia, making the United States its home market. Landis+Gyr sits one layer UPSTREAM of the consumer: it sells to the roughly 2,000 utilities that are themselves the regulated data holders, so no data-sharing mandate — not US Green Button, not Ontario's Green Button regulation, not Australia's Consumer Data Right for energy — attaches to Landis+Gyr itself. Its API posture reflects that. Landis+Gyr publishes NO open market or grid data and NO consumer usage API; the meter interval data its Gridstream Connect and MDMS products produce reaches households only after a utility customer re-publishes it, typically through a third-party Green Button–certified portal that Landis+Gyr does not operate. There is a real developer portal at developers.landisgyr.com — the Gridstream Connect Apps / Revelo edge-app program, with App Studio, documents, learning paths, a Stack Overflow Teams developer forum and a Revelo developer-kit request flow — but every content route renders empty without authentication, the registration path carries an admin invitation and approval workflow, and the corporate site never links to it: the public call to action on the Apps Ecosystem page is "Email Our Team", pointing at a sales inquiry form. No OpenAPI, Swagger, Postman collection, SDK download or endpoint reference is published anywhere in public. The only interoperability standard Landis+Gyr states publicly is Wi-SUN FAN certification (15 certified products) over standards-based IPv6 mesh — a network standard, not a customer-data standard.

Landis+Gyr is profiled on the APIs.io network. Tagged areas include Energy, United States, Utilities, Electricity, and Gas.

Landis+Gyr’s developer surface includes signup flow, developer portal, documentation, training material, support, engineering blog, YouTube channel, and 27 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.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/.
