UnderGround Weather (formerly AquaSpy)
From connected sensors to global soil intelligence: how TEAL's eSIM technology powers AI-driven agronomy across crops, climates, and continents.

About UnderGround Weather
At a glance
Company: UnderGround Weather™, formerly AquaSpy
Industry: Agriculture technology, soil intelligence
Devices: Crophesy™ LS-N below-ground probes
TEAL solution: Global eSIM connectivity with remote provisioning across 196+ countries
Outcome: Continuous underground data feeding the UnderGround Weather Reporter™ AI engine, from remote specialty crop operations to global channel partners
UnderGround Weather is building the world's largest real-time underground intelligence network for nutrient management. Formerly AquaSpy, the company brings nearly two decades of underground sensing experience to growers, agronomists, and agricultural channel partners worldwide.
Its Crophesy LS-N probes continuously measure nitrate, oxidation-reduction potential (ORP), moisture, salinity, and temperature throughout the root zone. The new UnderGround Weather Reporter AI engine combines those measurements with weather, soil, crop, and management data to produce concise agronomic reports. The result: growers see what is happening underground so they can make better decisions above ground.
UnderGround Weather is now expanding globally through strategic channel partners and specialty crop producers.

Where It Started
AquaSpy first partnered with TEAL to solve a hardware problem. Its legacy probes relied on solar panels, cables, and towers that critters and farm equipment regularly damaged. Rural coverage was inconsistent, and managing multiple carriers and physical SIM swaps slowed every new deployment.
TEAL's low-data, low-power eSIM technology helped AquaSpy launch Crophesy, a fully wireless below-ground probe. Devices could ship directly to the field and be provisioned over the air, with no SIM swaps or field testing. A single global profile opened the door to international markets as far away as Chile, Nigeria, and Egypt.
UnderGround Weather's Challenge
UnderGround Weather is no longer just selling sensors. It is delivering AI-powered soil intelligence at global scale, and that raises the stakes on connectivity.

AI needs a continuous data stream. UnderGround Weather Reporter is only as good as the underground measurements behind it. Gaps in data mean gaps in insight during critical points in the growing season.
Growth spans new countries and channels. Expanding through global channel partners means entering markets with different carriers, coverage, and commercial terms.
Fields are remote by nature. Specialty crop operations often sit where cellular coverage is challenging.
Agronomists' time is valuable. Technology Success Agronomists need to focus on helping growers interpret soil conditions, not troubleshooting connectivity.
Trust is the product. Channel partners and growers make nutrient and irrigation decisions based on these insights. The data has to get through.
How Teal Helped UnderGround Weather
TEAL's global eSIM technology is the connectivity foundation behind UnderGround Weather's global rollout.

Reliable connectivity in remote growing regions. TEAL's eSIM helps Crophesy probes connect to available cellular networks across rural and international agricultural markets.
Continuous data delivery. Dependable connectivity supports the steady flow of underground measurements that agronomists and UnderGround Weather Reporter rely on throughout the season.
Scalable global deployments. Access to a broad network of carriers across 196+ countries lets UnderGround Weather enter new markets without negotiating separate connectivity arrangements in each one.
Simplified field operations. Remote, over-the-air provisioning reduces physical SIM swaps and connectivity-related field visits, streamlining installation and ongoing support.
A foundation for AI-powered agronomy. With connectivity handled, UnderGround Weather's team can focus on what it does best: turning soil data into decisions.
The Results
With TEAL as its connectivity foundation, UnderGround Weather is scaling from soil sensing to soil intelligence.
1. Global reach for a growing network: Crophesy probes are deployed across multiple countries, including Canada, Sweden, Spain, Romania, Egypt, Uganda, Australia, Peru, and Chile, with over 10,000 active devices connected through TEAL. "We're taking UnderGround Weather into new countries and new channel partnerships, and connectivity can't be the thing that slows us down," said Peter Ellegaard, CTO, UnderGround Weather. "TEAL gives us one solution across 196+ countries, so entering a new market is a business decision, not a carrier negotiation."
2. Confidence in the data behind every insight: "When our Technology Success Agronomists and UnderGround Weather Reporter are helping growers make critical decisions, we need to trust that the measurements behind those insights are getting through. TEAL is an important part of making that possible," said Kathleen Glass, VP of Sales and Marketing, UnderGround Weather. Narrowband connectivity also means less drain on battery resources in the field.
3. Leaner field operations: Cutting the cables has contributed to a dramatic reduction in warranty-related truck rolls, helping teams install faster and support growers remotely.
4. Room to scale: "TEAL gives us peace of mind that our connectivity can scale with our ambitions, from remote specialty crop operations to strategic global agricultural partnerships," Glass added.
UnderGround Weather now benefits from:
Global carrier access: Connectivity across 196+ countries through one eSIM solution
Continuous data flow: A steady stream of root-zone measurements feeding AI-powered reports
Simpler expansion: No separate connectivity contracts for each new market
Fewer field visits: Remote provisioning in place of physical SIM swaps
More time for agronomy: Experts focused on growers, not connectivity troubleshooting
"Trust is at the heart of this partnership. Our channel partners and growers rely on us to deliver meaningful underground insights throughout the growing season, wherever their fields are located. TEAL is an important part of making that possible."
