Quick answer
GW2000 and GW3000 are both Ecowitt Ethernet and Wi‑Fi gateways supported by Home Assistant and Ecowitt’s official integration. For most Home Assistant users, either gateway works.
The primary documented differentiator in Home Assistant’s gateway list is that GW3000 includes data storage (“Ethernet and Wi‑Fi Gateway with Data Storage”), while GW2000 is listed as a standard Ethernet/Wi‑Fi gateway without that emphasis.
Choose GW3000 if you want onboard logging/storage features described in Ecowitt materials; choose GW2000 if you only need a LAN bridge for sensors and will store history in Home Assistant or InfluxDB.
Who this guide is for
- You are building an Ecowitt stack with Ecowitt WS90 or similar RF sensors.
- You read Best Weather Stations for Home Assistant and need to pick a hub.
- You want wired Ethernet — see also Ethernet weather station guide.
GW2000 vs GW3000 at a glance
| Feature | GW2000 | GW3000 |
|---|---|---|
| Ethernet | Documented | Documented |
| Wi‑Fi | Documented | Documented |
| Home Assistant (built-in Ecowitt) | Supported gateway | Supported gateway |
| Official Ecowitt HACS integration | Listed supported | Listed supported |
| Onboard data storage | Not emphasized in HA gateway label | With Data Storage (per HA docs) |
| Typical use | LAN bridge to HA | LAN bridge + gateway-side logging |
Specifications such as SD card support, memory, and retention policies should be verified on Ecowitt product pages for your regional SKU.
Home Assistant compatibility
Both gateways appear in:
Integration patterns:
- Built-in Ecowitt — configure Custom/DIY Upload Server on gateway → HTTP push to Home Assistant (requires HTTP reachability).
- Official Ecowitt (HACS) — Home Assistant polls gateway HTTP API on LAN.
IoT class for built-in integration: Local Push.
Local data and APIs
Ecowitt publishes LAN HTTP API documentation for developers and integrators. Both gateways sit on your LAN and aggregate 915 MHz / 868 MHz sensor traffic.
For architecture context, see local data guide.
Neither gateway choice changes sensor RF compatibility — verify sensor model matches gateway region and Ecowitt compatibility charts.
GW3000 data storage
Home Assistant’s gateway naming suggests GW3000 adds storage at the hub. Based on manufacturer positioning, this may suit buyers who want:
- Short-term onboard history if HA is offline
- Local buffering before upload to optional cloud services
If Home Assistant Recorder or an external time-series DB is your canonical history, GW2000 may be the simpler, lower-cost match.
Atmosiva has not independently measured storage capacity or retention — confirm on Ecowitt specs before relying on gateway logs for compliance or research.
Which gateway to buy
Choose GW2000 when:
- Home Assistant is your sole dashboard and historian
- You want the documented LAN bridge with minimal extras
Choose GW3000 when:
- You want Ecowitt’s data storage features at the gateway
- You may run mixed consumers (HA + local logging) and value hub-side retention
