Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-52bf52d931422d0b descriptive
Zurich's city-owned utility ewz and the municipal IT department OIZ
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The city's own article names both bodies and divides the work between them: the LoRaWAN was "das von ewz und OIZ aufgebaute LoRaWAN" (the LoRaWAN built by ewz and OIZ), with ewz responsible for moving sensor data through the gateways and for general network operation, and OIZ forwarding the data to the specialist applications. Akenza's announcement describes the same pairing: "the utility provider ewz, in cooperation with the city's IT organization OIZ has been operating the LoRaWAN infrastructure in the city of Zürich". ewz is the electricity utility owned by the City of Zurich, and OIZ is the city's own IT organisation.

Claim 2 clm-ba91c04168921579 descriptive
have run a citywide LoRaWAN
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The operator's own page states that "ewz betreibt in Zürich ein flächendeckendes LoRa-Netz" (ewz operates a blanket LoRa network in Zurich) and advertises "Perfekte Abdeckung in der ganzen Stadt Zürich" (perfect coverage across the whole city of Zurich). Akenza's announcement says the network "offers excellent network coverage in the Zurich city area". The ewz page is a live sales page and still describes the network in the present tense.
Caveat
Coverage is described only by the operator and its platform partner, in the language of a product page. No listed source gives a gateway count, a coverage map or a measurement by anyone outside the network's own operator.

Claim 3 clm-33f1b89158cbe5e5 descriptive
routing sensor data into the city's own data centre
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The city article describes exactly this path: the LoRaWAN acts "als Netzwerk zwischen Sensoren und dem Rechenzentrum der Stadt Zürich" (as the network between the sensors and the City of Zurich's data centre), and "Dabei ist ewz für die Datenübertragung von Sensoren über die verschiedenen Antennen (Gateways) in das OIZ-Rechenzentrum und den allgemeinen Netzbetrieb zuständig" (ewz is responsible for transmitting sensor data through the various gateways into the OIZ data centre and for general network operation).
Caveat
The same article describes a second, separate strand of ewz sensor work whose analysis platform was deliberately built in a commercial cloud rather than the municipal data centre, on the grounds that comparable capacity in the city's own centre would have cost several times as much. Not every ewz sensor project therefore ends up in the city's data centre.

Claim 4 clm-5829a9f0ae9b5de4 descriptive
offering it to every department
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The city article says the network "allen Dienstabteilungen der Stadt Zürich für die Übertragung von Messdaten zur Verfügung steht" (is available to all departments of the City of Zurich for transmitting measurement data), and that OIZ makes sure the components of the system work together and are available to the departments.
Caveat
What the city offers to every department is the network itself, as a way of transmitting their own measurements; the article does not say that data gathered by one department is shared with the others. OIZ is described as forwarding data to the specialist application that needs it.

Claim 5 clm-5aa745143183169b quantitative
a 185-space parking pilot at the Hallenstadion
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Marcus Cathomen of ewz is quoted describing the pilot: "185 Parkplätze beim Hallenstadion in Oerlikon mit Sensoren ausgerüstet und ins Parkleitsystem der Stadt Zürich integriert wurden" (185 parking spaces at the Hallenstadion in Oerlikon were fitted with sensors and integrated into the City of Zurich's parking guidance system), carried out with the traffic department and OIZ. He adds that "Aus diesem Pilotprojekt haben wir viele Erkenntnisse für weitere Zürcher IoT-Projekte gewonnen" (we gained many insights from this pilot project for further Zurich IoT projects).
Caveat
The account is ewz's own, published in the magazine ewz produces, and the article states that it first appeared in September 2019. The utility speaks of the pilot in the past tense, as a finished exercise it drew lessons from; no listed source says whether the sensors are still in the ground or whether the guidance system still uses them.

Claim 6 clm-74a74345e01212eb quantitative
16 chair sensors
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The ETH News report of the city's results, republished by Netzwoche, says the civil engineering office and ewz tested 16 of the sensors developed with ETH Zurich in August and September 2022, eight each on the Münsterhof and the Vulkanplatz.

Claim 7 clm-d2d204f064d288bf descriptive
that measured how two public squares are used
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The city's announcement says the civil engineering office, together with ewz and ETH Zurich, tested newly developed sensors on the Münsterhof and the Vulkanplatz until the end of September 2022: "testet das Tiefbauamt zusammen mit ewz und der ETH Zürich auf dem Münsterhof und dem Vulkanplatz bis Ende September 2022 neu entwickelte Sensoren". It states what they record — "Die Sensoren messen die Belegung und Verweildauer auf den Stühlen" (the sensors measure occupancy and dwell time on the chairs), along with the chairs' location, temperature, humidity and noise level — and that "ewz stellt für die drahtlose Datenübertragung sein «LoRaWAN» bereit" (ewz provides its LoRaWAN for the wireless transmission).
Caveat
What the sensors measured was the use of the chairs — where they stood and how long people sat on them — rather than the use of the squares as a whole. The city describes a test running to the end of September 2022, undertaken to see whether such sensors could later serve the planning of public space.
