Station & Manufacturer Requirements ​

Reviewed: August 2026

Hardware Certification Inquiries

If you are an IoT or meteorological instrument manufacturer interested in building Association-certified WeatherXM stations, review the formal technical specification: Hardware Specifications PDF (v20240924) and contact the hardware working group at partner@weatherxm.com.

The WeatherXM Network Association maintains an open certification program for third-party hardware manufacturers. The goal is to cultivate a decentralized, multi-vendor ecosystem providing stations across diverse price points, connectivity environments, and industrial durability requirements.


Technical Specifications Overview ​

Certified WeatherXM stations must meet strict meteorological accuracy, data integrity, and communication requirements as defined in the official specification:

1. Mandatory Sensor Capabilities ​

All certified stations must measure the core surface meteorological variables:

  • Ambient Temperature: Range -40°C to +65°C; accuracy ±0.3°C.
  • Relative Humidity: Range 0% to 100%; accuracy ±3% RH.
  • Barometric Atmospheric Pressure: Range 300 to 1100 hPa; accuracy ±1 hPa.
  • Wind Speed & Direction: Range 0 to 50 m/s (180 km/h); accuracy ±0.5 m/s or ±5%.
  • Precipitation / Rain Gauge: Resolution 0.1 mm or better; self-emptying tipping bucket or solid-state acoustic/optical sensing.
  • Solar Irradiance & UV Index: Global solar radiation up to 1400 W/m² and UV index 0 to 15.

2. Device Identity & Cryptographic Attestation ​

To prevent spoofing and data falsification:

  • Each hardware device must include a secure element (or secure microcontroller enclave) holding a unique, tamper-proof private key provisioned during manufacturing.
  • Data packets transmitted to the network must carry cryptographic signatures generated at the edge by the hardware device.

3. Environmental Durability & Autonomy ​

  • Outdoor components must achieve an IPX5 rating (or higher) with UV-stabilized polycarbonate housing.
  • Stations must be engineered for autonomous energy operation using high-efficiency solar harvesting with lithium-iron-phosphate (LiFePO4) or supercapacitor backup.

Certification & Onboarding Process ​

  1. Specification Review: Manufacturer reviews the Hardware Specifications PDF and submits a formal Expression of Interest.
  2. Prototype Evaluation: Manufacturer ships production-ready sample prototypes to the Association's testing lab for environmental chamber validation and sensor calibration benchmarks.
  3. Firmware & Key Provisioning Audit: The Association inspects edge firmware, cryptographic signing pipelines, and provisioning security.
  4. Onboarding Fee Payment: The manufacturer pays the mandatory $100 USD onboarding fee per device batch to the Association Treasury.
  5. Registry Inclusion: Certified device public keys and model identifiers are entered into the network's on-chain device registry.

Certified Manufacturers ​

The following manufacturers are currently certified to produce network-compatible hardware:

  • WeatherXM AG — D2 Mesh, Pulse LTE, H2 LoRaWAN, D1 Wi-Fi.
  • EXM PC — Commercial and early network hardware designs.
