Lufft Weather Stations
Lufft WS-series compact all-in-one weather sensors (UMB over RS485). One maintenance-free housing combines a model-dependent subset of air temperature, humidity, barometric pressure, ultrasonic wind, radar or rain-gauge precipitation, and global radiation; the WS800 adds lightning detection.

On the platform
What Lufft Weather Stations Get From Aethair
Connected through Thiamis, its readings arrive in the same Environet account as Aethair's own monitors.
Live data and alerts
Environet shows the instrument live and alerts the people you choose by email, SMS, and webhook, at the thresholds you set. Noesis sets up a dashboard, a report, or an alert from a plain-text request.
Compliance reports
Aethair Reports produces scheduled or on-demand reports from the instrument's readings, as a PDF or secure link. Templates cover Aethair Blue, WELL v2, cabin air (ISO 23875), and the CMS-2567 healthcare codebook (ASHRAE 170), or you can report against custom limits such as OSHA PELs, NAAQS, EPA guidance, or your own program limits.
Dashboards and the app
Environet dashboards and the Aethair App show the instrument's readings just like any Aethair device. The occupant-facing Aethair Dashboards status display is built around Aethair IAQ and Aethair PRO.

Questions
Lufft Weather Stations FAQ
How does the Thiamis integration read a Lufft WS sensor?
Over RS485 using Lufft's UMB binary protocol. The driver auto-detects the connected model from its device-ID string, queries the device's available channel list, then polls those channels each interval, so any WS-family model works without per-model configuration.
How do the WS models differ?
They share one maintenance-free housing but differ by sensor fit. WS200 is wind-only (ultrasonic plus electronic compass); WS100 is precipitation-only (radar). WS300 measures temperature, humidity, and pressure; WS400 adds radar precipitation, WS500 adds ultrasonic wind, WS600 adds both; WS700 adds global radiation and WS800 adds lightning. The x01–x10 variants (e.g. WS301, WS501) add a global-radiation pyranometer to the base model.
Radar or rain gauge for precipitation?
Most precipitation models (WS100, WS400, WS600, WS700, WS800) use a 24 GHz Doppler radar that derives quantity, type, and intensity by correlating drop size and speed. WS401 and WS601 instead use an unheated tipping-bucket rain gauge, recommended for low-power installations. Radar precipitation models are subject to country-specific radio approvals.
Is wet-bulb temperature reported?
Wet-bulb temperature is a supported UMB channel (114/119) that every temperature/humidity/pressure model calculates, and it is listed here as a device capability. The current Thiamis firmware does not poll it by default, but it can be added to the request list on demand without any hardware change.
Is the WS800's lightning data available?
The WS800 detects lightning by analyzing the radio emissions of strikes and reports a strike count over UMB. The current Thiamis driver does not ingest the lightning channel, so it is noted on the WS800 but is not among the delivered parameters.
What does the electronic compass do?
Wind models carry an electronic compass used to verify the housing's north–south alignment and to output a compass-corrected wind direction; it is not reported as a separate measurement.
