Is there a free plan?
Yes — WindRose is free forever, no credit card: one public station with every weather feature, 3 months of full-resolution history, daily summaries kept forever, alerts and the AI assistant. It works with every supported brand. Pollutant dispersion is the one tool kept for Business.
Can I pay yearly?
Yes, and it costs less: Pro is €30/year instead of €36 (12 × €3), about 17% off. Business is sold yearly only: €100/year plus VAT where due.
What do Pro and Business add over Free?
Pro takes you to 3 stations, two years of full-resolution history imported from your provider, live data and alerts every 5 minutes, unlimited alerts, monitoring and exports, and the stations whose history only WindRose keeps (Davis Basic, direct upload, CSV import). Business goes to 10 stations that can be private, unlimited history, live data every minute, the REST API, commercial use and your own logo.
What about commercial or reseller use?
Commercial use is included in Business. For more than 10 stations, installers and distributors, the Reseller plan is on the way: create and manage your customers' accounts, build your own service packages, volume pricing on a single invoice. For a negotiated station allowance, a redistribution licence or an SLA, contact us from the Reseller card.
