Ecowitt Weather Hardware & Sensors
Modular weather-monitoring ecosystem with gateways and a broad range of compatible expansion sensors
About the Ecowitt Hardware Platform
Ecowitt offers an open, modular personal weather-monitoring ecosystem. Buyers typically choose outdoor sensors such as the WS90 plus a compatible gateway (GW2000-class or GW3000), or a complete kit such as the GW2001 (GW2000 + WS90). Gateways support Wi-Fi and Ethernet where documented, Ecowitt.net cloud options, and local network / Home Assistant-compatible workflows — without locking buyers into a single console-only package.

RF 915/868/433MHz Sensors (e.g. WS90) -> Hub Gateway (GW2000/GW3000) or complete kits like GW2001 (GW2000 + WS90) -> Local Network / Ecowitt.net / Home Assistant
Core Strengths
- ✓ Broad RF modular add-on sensor catalog (soil, air quality, lightning, leaf wetness, water leak, and more)
- ✓ Gateway choice with documented local network data paths and no subscription for core gateway use
- ✓ Solid-state ultrasonic wind and haptic rain hardware (WS90 / WittBoy line)
- ✓ 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. The GW2001 commercial kit includes the GW2000 gateway plus WS90; GW2000 and GW3000 remain headless hubs for modular builds — GW3000 adds documented microSD local storage and higher expansion capacity.
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
Channel limits for soil, lightning, air-quality, and other add-ons vary by gateway or console model and firmware — check Ecowitt documentation for your hub before planning a multi-sensor install.

Brand Comparisons
Ecowitt WS90 
Ambient Weather Ecowitt vs Ambient Weather Stations: Which System Fits Your Setup?
Choose Ecowitt WS90 + a compatible gateway when you want modular expansion, gateway flexibility (including Ethernet on GW2000/GW3000-class hubs), and room to add sensors later. Choose Ambient WS-5000 when you want a more conventional complete station package with an included console, separated outdoor sensors, and a Wi-Fi cloud/app workflow. There is no universal winner — the better fit depends on modular vs console-first priorities.
Ecowitt WS90 
Tempest Weather Ecowitt WS90 vs Tempest: Modular Sensor + Gateway vs All-in-One System
Choose WS90 for modular expansion and gateway flexibility; choose Tempest for a simpler complete system with built-in lightning. There is no universal winner — the better fit depends on whether you want an expandable Ecowitt stack or a complete retail Tempest package.
Ecowitt WS90 
Ambient Weather Ecowitt WS90 + Gateway vs Ambient WS-1965: Which Home Assistant Weather Setup Fits?
For a Home Assistant buyer, Ecowitt WS90 plus a compatible gateway is the better fit when you want to choose the gateway and use a documented local-data path. Ambient WS-1965 is the better fit when you want one packaged station with a color console and Ambient Weather Network, and you do not need a documented Home Assistant or local-data path. Basic outdoor readings can come from either setup. There is no universal winner.
Ecowitt WS90 + Gateway Ambient WS-1965 Ecowitt WS90 vs Ambient WS-1965: Sensor + Gateway Setup or Console Station?
Compare the Ecowitt WS90 sensor plus a compatible gateway path against the packaged Ambient WS-1965 console station for Home Assistant fit, local-data options, expansion sensors, and setup simplicity.
