The weather station with no moving parts: ultrasonic wind and an acoustic rain sensor, solar-powered, in one pole-mounted unit. It is also one of the few stations where HA gets local data: the hub broadcasts readings on your LAN over UDP and Home Assistant listens, with a cloud integration as an alternative. £349 is steep next to an Ecowitt, so buy it for the low-maintenance, no-moving-parts design and the UDP local feed rather than for value.
What can Home Assistant control on the WeatherFlow Tempest?
| Control | Type | What it does |
|---|---|---|
| Wind speed / gust / direction | Sensors | ultrasonic wind |
| Rain | Sensors | acoustic rain rate and accumulation |
| Lightning | Sensors | strike count and distance |
Use the WeatherFlow integration (local UDP) for wind, rain, pressure, UV, light and lightning sensors; Home Assistant must be on the same network segment as the hub for broadcasts to arrive. Rain and lightning events are accumulated in short bursts, so templates for 'rained in the last hour' are better than reacting to single readings.

Frequently asked questions
- Does the WeatherFlow Tempest work with Home Assistant locally?

- Which protocol does the WeatherFlow Tempest use, and do I need a hub?
- The WeatherFlow Tempest uses Wi-Fi. To pair it with Home Assistant you need no hub — it joins your Wi-Fi network directly. WeatherFlow's own hub is not required when you integrate through a built-in Home Assistant core integration (WeatherFlow).
- How much does the WeatherFlow Tempest cost in the UK?
- The lowest price we have listed for the WeatherFlow Tempest is £349 at Amazon UK. Prices were last checked in October 2026 and change often, so confirm on the retailer's page before buying.
