Official stations publish their siting and instrumentation; hobby stations usually do not. Everything an observation needs to be interpreted honestly is here, including where this station falls short of the standards.
The WMO standard for wind is 10 m over open ground, and 1.25–2 m for temperature. Readings here are not height-corrected: if the anemometer is below 10 m, wind will read lower than an official station in the same air.
Readings are polled from the gateway over the local network every 16 seconds and archived once a minute. Nothing passes through a manufacturer's cloud service, and the station keeps recording during an internet outage.
Everything on the dashboard is served as JSON, and the archive is downloadable as CSV. The data page lists every endpoint, how often each is written, and which parts are this station’s own to give away and which belong to somebody else.
| /api/daily.csv | every day on record, one row each |
| /api/history.json | 24 h of observations, records, climatology |
| /station.json | this page, as data |
Questions about any of this — a reading that looks wrong, the minute-resolution archive, permission to use something in a way the terms do not obviously cover — to [email protected]. It is a real address and a person reads it.

Battery voltage and signal strength never reach the archive — they arrive in live packets and are published to the broker — so this is the one part of the station that could fail silently while every reading on the dashboard still looked plausible. Thresholds are per sensor because the cells differ: a WH40 is a 1.5 V battery while a WS90 runs off a supercapacitor near 3 V, and one shared limit would permanently mislabel one of them.
