About

Personal Weather Station is a custom integration that receives data from personal weather stations over HTTP. It runs locally and exposes the incoming readings as sensors, such as temperature, humidity, pressure, wind speed and rainfall. Sensors are created automatically for any supported data key, and existing ones are updated as new requests arrive. A station key acts as a password between the station and Home Assistant, and it is entered when the integration is added in the UI. Stations that can send HTTP GET requests with matching query parameters should work, and several Bresser and YOUSHIKO models are listed as confirmed. For stations without a custom upload URL, the README describes workarounds that intercept Weather Underground traffic.

From the README

Turn Home Assistant into the server your weather station uploads to. No cloud, no account, no polling: the station posts straight to your instance, and its devices and sensors appear on their own.
Guided setup. Adding the integration ends on the exact settings to enter in your station, your Home Assistant address included. Until a station has posted, a prompt waits with you for its first…
170 sensors across both protocols: temperature, humidity, pressure, wind, rain, lightning, air quality, multi-channel sensors, batteries.
North calibration. Realign a vane that was not mounted precisely, without touching the hardware.
A station that stops reporting is marked unavailable instead of showing a frozen reading forever.
A Last update diagnostic per station, readable precisely when the station has gone quiet.
Water leak and connection readings as binary sensors, usable with the standard leak cards and alerts.
Entities and values survive a restart — no waiting for the next upload.
Rejected stations are reported in Repairs rather than failing silently.
Available in all 64 languages Home Assistant supports.
Optional station key.
