Quick verdict
The Wittboy kit is the value pick for a Home Assistant weather station. The WS90 array measures almost everything the Tempest does and the GW2000 gateway pushes it locally, with a wired Ethernet port if you want it. You give up built-in lightning detection and have to keep an http:// path open to Home Assistant, but for $200 it is a lot of local weather data.
Standout: Full 7-in-1 outdoor array plus an Ethernet-capable gateway that pushes readings locally to Home Assistant's core Ecowitt integration.

Local control facts
Home Assistant: ecowitt integration, Local Push (home-assistant.io, checked Oct 10, 2026)
Why it stands out
WS90 sensor array covers wind (ultrasonic), rain (piezo), temperature, humidity, light, and UV in one solar-powered unit
GW2000 gateway has both Ethernet and Wi-Fi and pushes to Home Assistant locally over the core Ecowitt integration
about $150 cheaper than a Tempest for a similar sensor set
Reasons to hesitate
no lightning detection, so a storm-front automation needs Ecowitt's separate WH57 lightning sensor
Ecowitt gateways only push over plain HTTP, so Home Assistant must be reachable on an http:// address on the LAN
no display console in this kit, which is fine for Home Assistant but not for a glance-at-the-wall setup
Best for
Home Assistant users who want a full outdoor station with local push and a wired gateway option
anyone planning to grow the setup with Ecowitt's add-on soil, pool, and lightning sensors
Avoid if
you need lightning detection out of the box
your Home Assistant is only reachable over HTTPS with no plain-HTTP LAN address
Privacy and local-control notes
The GW2000 gateway pushes readings straight to a Home Assistant webhook on your LAN. Uploading to Ecowitt, Weather Underground, or WeatherCloud is optional, and the gateway can be configured from its own local web page without an Ecowitt account.
