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.; Teralytic the company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
  • They diverge on capability: Davis Instruments WeatherLink covers Per-station cloud dashboards, Teralytic covers Wireless NPK sensing.
  • 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.

Teralytic

  • The company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
  • No current pricing is published and reported figures have moved between roughly 300 and 500 US dollars per probe per year, so a buyer cannot model the cost of a hundred-probe deployment without a quote.
  • The subscription is mandatory for the probe to report at all, so the up-front hardware payment buys nothing durable and a lapsed account means a field full of dead instruments.
  • In-field NPK sensing is scientifically contested and readings need interpretation against soil type and calibration, so agronomists will not treat the numbers as interchangeable with a lab test and many will insist on both.
  • Spatial coverage is the unsolved problem: a probe measures one point, soil varies over metres, and covering a field properly multiplies both the hardware and the annual subscription by the number of zones you care about.

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.

Teralytic: Can I buy the probe without a subscription?

No. The probe reports through Teralytic’s network into its cloud, and without an active subscription it does not deliver data.

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.

Teralytic: Does it replace lab soil tests?

No. It gives continuous in-season trend data. Most agronomists will still want lab results for absolute nutrient values and for compliance records.

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

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

Teralytic: How much does it cost?

Teralytic does not publish current pricing. Reported figures have ranged from roughly 300 to 500 US dollars per probe per year including hardware and connectivity.

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.

Teralytic: How many probes does a field need?

That depends on soil variability. One probe represents one point, so a field with several distinct soil zones needs one per zone to be meaningful.
