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.; METER Group ZENTRA hardware costs several times what commodity soil probes cost, so a farm that only needs a rough irrigation trigger is paying for calibration accuracy it will never use.
  • They diverge on capability: Davis Instruments WeatherLink covers Per-station cloud dashboards, METER Group ZENTRA covers TEROS soil sensors.
  • 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.

METER Group ZENTRA

  • Hardware costs several times what commodity soil probes cost, so a farm that only needs a rough irrigation trigger is paying for calibration accuracy it will never use.
  • ZENTRA Cloud is a per-device subscription, so a large sensor network carries a recurring bill that grows linearly with every probe added and is easy to underestimate at design stage.
  • The three-year subscription bundled with the ZL6 Pro means the renewal decision arrives exactly when a typical research grant has ended, which is how long-running datasets get abandoned.
  • METER sells measurement rather than recommendations; there is no irrigation scheduling engine, so someone has to turn the numbers into decisions or buy a second platform that will.
  • Installation quality dominates results with soil sensors, and a badly installed TEROS probe produces confidently wrong data, so the accuracy you paid for depends on field technique the vendor cannot supply.

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.

METER Group ZENTRA: Is ZENTRA Cloud included with the loggers?

A three-year subscription is included with the ZL6 Pro. Other loggers require a separate per-device subscription.

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.

METER Group ZENTRA: Do I need a separate cellular data plan?

No. Cellular data is covered within the device subscription rather than billed as a separate SIM contract.

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

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

METER Group ZENTRA: Will it tell me when to irrigate?

No. METER provides measurement, not scheduling recommendations. You either interpret the data yourself or feed it into a scheduling platform.

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.

METER Group ZENTRA: Why is it more expensive than commodity soil probes?

Individual sensor calibration and documented measurement physics, which is what makes the data hold up in research, regulatory and legal contexts.
