Quick verdict
The Tempest is the backyard station I actually run. The core Home Assistant integration listens to the hub's UDP broadcast, so pressure, wind, UV, and lightning show up locally every minute with no account. It is the priciest option here and its rain sensing is an estimate rather than a bucket, but as a low-maintenance, fully local data source for weather automations it is hard to beat.
Standout: Single sealed sensor with lightning detection, UV, and local UDP broadcast that the core Home Assistant integration reads with no cloud in the loop.

Local control facts
Home Assistant: weatherflow integration, Local Push (home-assistant.io, checked Sep 10, 2026)
Why it stands out
one solid-state unit with no moving parts covers pressure, temperature, humidity, wind, rain, UV, solar, and lightning
fully local in Home Assistant over UDP with no account or API key required
sensor is solar powered, so there is nothing to charge or replace on the pole
Reasons to hesitate
the included hub needs 2.4 GHz Wi-Fi and Home Assistant must sit on the same subnet for the local integration
haptic rain sensing is less precise than a physical tipping bucket in light rain
premium pricing compared with an Ecowitt kit that measures most of the same things
Best for
Home Assistant users who want a set-and-forget backyard station with lightning and UV in one package
anyone building pressure or storm automations who needs fast, local barometric readings
Avoid if
you want tipping-bucket rain accuracy for gardening or irrigation math
you are on a tight budget, since an Ecowitt WS90 kit measures most of this for about $150 less
Privacy and local-control notes
The Tempest hub broadcasts every reading over UDP on your LAN and the core Home Assistant WeatherFlow integration reads it directly, so the raw data never has to leave the house. The optional cloud account only adds forecasts, the phone app, and remote access.
Home Assistant support: supported · integration path: weatherflow.
