The short version

  • Only Davis Instruments WeatherLink has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; GEA DairyNet the value depends on GEA hardware, so a barn with mixed-vendor parlours, sensors or feeders loses most of the native integration that justifies the software.
  • They diverge on capability: Davis Instruments WeatherLink covers Per-station cloud dashboards, GEA DairyNet covers Herd module.
  • 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.

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.

GEA DairyNet

  • The value depends on GEA hardware, so a barn with mixed-vendor parlours, sensors or feeders loses most of the native integration that justifies the software.
  • Nothing is published: not module prices, not per-animal rates, not installation costs, so every comparison against DeLaval or Lely requires a dealer quote and there is no way to sanity check it.
  • Per-module per-animal pricing is granular but also means costs climb quietly as you add modules and grow the herd, and the monthly cancellation option does not help once the barn depends on a module.
  • It is a successor to DairyPlan C21 rather than a rewrite of the category, so dairies migrating carry across conventions and data structures that predate cloud software and the transition itself needs dealer time.
  • GEA sells only through authorised partners, so support quality, installation competence and how quickly you get a fault fixed are determined by your regional dealer rather than by GEA.

Answered from the vendors’ own pages

Davis Instruments WeatherLink: Is WeatherLink free?

There is a permanently free Basic tier with charting and export, but third-party uploads run only every 15 minutes and there are no shareable links.

GEA DairyNet: Does DairyNet replace DairyPlan C21?

Yes. It is the successor product, built on the same decades of DairyPlan development but restructured into cloud-connected modules.

Davis Instruments WeatherLink: What does the paid tier actually add?

Faster upload intervals, five minutes on Pro and one minute on Pro+, plus shareable public links. The faster cadence is what matters for frost and spray timing.

GEA DairyNet: How is it priced?

Per module, with each module priced on the number of animals actually using that module's functions. Modules can be cancelled monthly. No rates are published.

Davis Instruments WeatherLink: Is pricing per account or per station?

Per device. Every station you own needs its own subscription.

GEA DairyNet: Will it work with non-GEA milking equipment?

Basic herd records will, but the sensor, robot and parlour integrations that make it worth buying are GEA-specific.

Davis Instruments WeatherLink: Can I get the data out via an API?

Yes, Davis publishes a WeatherLink API, but practical use depends on your account tier and station model, so confirm before designing around it.

GEA DairyNet: Is the software cost the main expense?

No. The one-time investment in sensors, system technology and installation is the larger figure, and it is quoted separately by the sales partner.
