WeatherXM D1 pairs a solar-powered outdoor station with the WG1200 gateway, a 4-inch touchscreen console that bridges LoRa to Wi-Fi, your local network and Meshtastic or MeshCore.
The technology
The outdoor station never touches your Wi-Fi. It sends its readings over a private LoRa radio link to the indoor gateway, and the gateway handles everything else.
Topology
Point-to-point means the station talks only to its own paired WG1200. There is no LoRaWAN network server, no third-party gateway and no network subscription between the sensor and your home. The gateway can be set to listen for its saved station, or pair locally.
Why LoRa, not Wi-Fi
LoRa uses chirp spread-spectrum on sub-GHz bands (EU868, US915, AS923), which passes exterior walls far better than 2.4 GHz Wi-Fi and needs a fraction of the energy. The station runs on its solar panel with AA backup and sends a packet roughly every 20 seconds.
Trust · at the gateway
The WG1200 carries an ATECC608 secure element and GPS. It cryptographically protects each observation and its location before forwarding, so data leaving your home can be verified as coming from your station.
Same radio family, different topology for different sites.
| LoRa P2P | LoRaWAN | LoRa mesh | |
|---|---|---|---|
| Topology | Station ↔ its own gateway | Station → any gateway → network server | Stations relay through other mesh nodes to reach the console |
| Distance | Up to ~1 km line of sight | Typically 2–10 km to a gateway | 100+ km, extended hop by hop |
| Needs on site | Wi-Fi and USB power for the gateway | LoRaWAN coverage in range | Other mesh nodes |
| Station | D1 Wi-Fi | H2 LoRaWAN → | D2 Mesh → |
Signal path
The WG1200 receives the station over LoRa, then serves the same observations to the cloud, to your local network and to the mesh at the same time.
The solar-powered outdoor unit samples temperature, humidity, pressure, wind, rain and light.
About every 20 seconds it sends a LoRa packet straight to its paired WG1200 indoors.
The gateway decodes it, shows live conditions on its 4-inch screen and protects it with its secure element.
Observations go to the cloud over Wi-Fi every minute, to your LAN on request, and to the mesh as telemetry.
WG1200 gateway · both editions
Every D1 gateway, Network or Open Edition, works on your own network and on the mesh. The cloud is one destination, not a dependency for local use.
The gateway serves a web interface and a REST API over HTTP on your LAN. Read live observations straight from the device, with no internet round trip and no cloud account in the loop.
The gateway can act as a Meshtastic or MeshCore environmental sensor, sharing full weather from your station with nearby mesh nodes. Already running a home node? D1 puts real wind, rain and pressure on your mesh.
The gateway requires USB power.
Network Edition forwards over Wi-Fi every minute to the WeatherXM app, Explorer and Pro API. Open Edition follows an independent backend path for private deployments.
Already own a D1? The latest local-UI and mesh firmware is rolling out in stages to existing gateways over the air—or you can install it immediately (and switch modes) over USB at flasher.weatherxm.com, or inspect and build on the public wg1200-firmware repository on GitHub.
Smart home
Automations on real conditions
Close awnings on wind, pause irrigation after rain, tune heating to the outdoor temperature at your own address.
Facilities
Building management
Feed on-site weather into BMS and HVAC control over the LAN, independent of internet availability.
Agriculture
Greenhouses & nurseries
Drive vents, shading and irrigation controllers from the station, with microSD logs as a local record.
Communities
Mesh weather feeds
Share live conditions with Meshtastic or MeshCore users nearby, even when the internet is down.
Installation
Station outdoors, in the open
On a metal pole at least 2 m high, away from walls and trees that distort wind and temperature.
Gateway within LoRa range
Up to about 1 km with line of sight. A window facing the station helps; concrete, metal and coated glass reduce range.
Gateway on Wi-Fi and USB power
Needs a 2.4 GHz Wi-Fi signal and a USB power supply. The USB-C cable is in the box; the power adapter is not.
Hardware editions
Identical station and gateway. Both editions include the local web UI, LAN REST API and Meshtastic/MeshCore telemetry.
Lower-priced edition for stations contributing observations under WeatherXM Network rules. Reward eligibility depends on the applicable Network rules and contribution quality.
For private and business deployments without a WeatherXM participation commitment, with the model-specific independent backend and firmware path.

Questions
Wi-Fi is power-hungry and struggles through exterior walls. The D1 station instead sends compact LoRa packets to the indoor WG1200 gateway, which runs on USB power next to your router and handles Wi-Fi. That lets the station run on a small solar panel with AA batteries as backup.
No. D1 uses LoRa point-to-point: the station talks only to its own paired WG1200 gateway, with no LoRaWAN network server or third-party gateway involved. H2 uses LoRaWAN and can reach public or private gateways kilometers away.
Yes. The WG1200 gateway serves a local web UI and an HTTP REST API on your LAN in both editions, so Home Assistant, Node-RED or your own software can read observations directly from the gateway. If your existing D1 gateway has not received the staged OTA firmware rollout yet, you can install the latest firmware immediately over USB at flasher.weatherxm.com.
The WG1200 gateway can act as a Meshtastic or MeshCore environmental sensor, sharing the station’s weather telemetry with nearby mesh nodes—or run full Meshtastic firmware via flasher.weatherxm.com. Both editions support it. The gateway needs USB power.
The hardware is identical. The Network Edition is lower-priced because the station contributes observations under WeatherXM Network rules. The Open Edition is for independent, private deployments without a WeatherXM participation commitment. Both include the local LAN API and mesh telemetry.
Up to about 1 km with clear line of sight. Walls, especially concrete, metal and coated glass, reduce that, so place the gateway near a window facing the station.
All store prices exclude VAT and include free shipping to 25 countries. EU customers pay 0% customs duty; local VAT is added at checkout, or 0% VAT (intra-EU reverse charge) if you enter a valid EU company VAT number verified in VIES (conditions apply). US customers pay $0 EU VAT at checkout, but because D1 is manufactured in China and ships from our Netherlands warehouse via DHL Express, US Customs assesses import duty upon entry. Based on customer reports and user-provided estimates, planning for an estimated ~37.5% import tariff (e.g., illustrative ~$75 on $199 Network Edition or ~$112 on $299 Open Edition, plus variable carrier disbursement/clearance fees) is recommended pending confirmation by your customs broker. For US businesses, equipment purchases and associated import fees may qualify as deductible business expenses depending on tax status—consult your tax advisor. If you want $0 US import duty and have Helium or LoRaWAN coverage, WeatherXM H2 ships directly from our US warehouse.
Mount the station, plug in the gateway, and read your weather wherever you need it.
