Ecowitt Weather Hardware & Sensors
The undisputed champion of modular sensors, local API push, and value
About the Ecowitt Hardware Platform
Ecowitt has revolutionized the hobbyist and prosumer weather station market by offering an open, modular ecosystem. Rather than locking users into a closed cloud dashboard, Ecowitt gateways (like the GW1100, GW2000, and WittBoy) support direct local HTTP POST requests, enabling seamless local push into Home Assistant, MQTT brokers, and custom self-hosted databases.
RF 915/868/433MHz Sensors -> Hub Gateway (GW1100/GW2000) -> Local Network / Ecowitt.net / Home Assistant
Core Strengths
- ✓ Over 35+ specialized RF modular add-on sensors (soil, air quality, lightning, leaf wetness, water leak)
- ✓ First-class local network data push with zero subscription fees
- ✓ Solid-state ultrasonic wind & haptic rain hardware (WS90/WittBoy Pro)
- ✓ Extremely competitive modular pricing with documented expansion sensors
Product Families
WittBoy & WS90 Solid-State Line
Smart home integrators wanting maintenance-free ultrasonic sensors
Eliminates all mechanical bearings and tipping buckets, utilizing ultrasonic acoustic sensors and piezoelectric shock plates.
Modular Pro Series (WS68 + WH40 + WS69)
Users who prefer traditional mechanical cups and separate rain funnels
Allows mounting the wind sensor high on a mast and the rain gauge at accessible ground level.
Environmental Add-On Sensors
Gardeners, greenhouse operators, and indoor air quality monitoring
Up to 8 channels per sensor type supported simultaneously on a single gateway hub.

Brand Comparisons
Ecowitt WS90 
Ambient Weather Ecowitt vs Ambient Weather: Local Home Assistant vs All-in-One Console
Ecowitt WS90 with a GW2000/GW3000 gateway is a better fit when you want documented local Home Assistant integrations and modular sensor expansion. Ambient WS-5000 is a better fit when you want a polished console bundle with integrated display and are comfortable with AmbientWeather.net for cloud features — using Custom Server community tools if you require local push.
Ecowitt WS90 
Tempest Weather Ecowitt WS90 vs Tempest: Modular Gateway vs All-in-One Smart Home
Ecowitt WS90 with a GW2000/GW3000 gateway fits buyers who want documented local Home Assistant integrations and modular add-on sensors such as soil moisture probes. Tempest fits buyers who want a single outdoor unit with built-in lightning detection and documented Rachio smart irrigation integration.
