The short version

  • Only Davis Instruments WeatherLink has a free tier, so it costs nothing to try first.
  • Each has a real cost: ClearAg no published pricing for ClearAg or DTN agricultural data services; Davis Instruments WeatherLink pricing is per device, so a grower with a dozen stations pays a dozen subscriptions, and at Pro+ that is over 1,200 US dollars a year in software on top of hardware that already cost several thousand.
  • They diverge on capability: ClearAg covers Spray window predictions, Davis Instruments WeatherLink covers Per-station cloud dashboards.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ClearAg

  • No published pricing for ClearAg or DTN agricultural data services

Davis Instruments WeatherLink

  • Pricing is per device, so a grower with a dozen stations pays a dozen subscriptions, and at Pro+ that is over 1,200 US dollars a year in software on top of hardware that already cost several thousand.
  • The free tier only uploads to third parties every 15 minutes, which is too coarse for frost protection and short-interval spray decisions, so the tier that exists is not the tier a commercial grower can use.
  • Davis directs bulk device management to a sales conversation rather than publishing a volume discount, so large networks cannot budget from the public rate card.
  • Three-year commitments are the only way to reach the lower per-device rate, which locks a grower into a platform for longer than a station deployment plan often survives.
  • The hardware is durable enough to outlive several software generations, and owners of older Vantage stations have repeatedly had to buy new data loggers or gateways to stay compatible with the current cloud, turning a maintenance-free instrument into a recurring purchase.
