CropX: If you want soil moisture with an irrigation recommendation engine attached

Buried wireless soil sensors with a ten to twenty year battery and no cables to the surface
As of 1 September 2026, Soil Scout's pricing is not published; the vendor quotes on request. Finnish sensors you bury and forget: no aerial, no stake, nothing for a mower or a plough to hit. Softwr lists it under Agriculture. Soil Scout is available on Web.
Overview
Soil Scout makes fully buried wireless soil sensors that transmit through the soil itself to a pole or building-mounted base station, which then uploads to the Soil Scout Hub cloud dashboard. Each sensor measures volumetric water content, temperature and salinity. The engineering claim that matters is longevity and invisibility: the Hydra100 is rated for up to twenty years of buried operation and the Happi100 for up to ten, with nothing protruding above ground. A single base station covers up to a kilometre and can carry over a thousand sensors, and the sensors need no individual data plans because they reach the base station rather than a mobile network. That design is a direct answer to why soil sensor deployments fail. Conventional probes have an above-ground antenna or logger that gets hit by a mower, a boom, a plough or a spectator, or a battery that needs replacing on a schedule nobody keeps. Soil Scout removes all of those failure modes by making the sensor a sealed object below working depth. The cost is that you cannot service it: if a sensor is wrong or dies early, it is under the pitch or under the crop and the recovery is a spade. The buyer profile follows from that. Golf course superintendents, stadium and sports turf managers, and research or high-value agricultural sites where the ground is worked or trafficked and a surface installation would not survive. It is a measurement system rather than an irrigation controller, so it reports and alerts but does not open a valve, and integration with the irrigation control system is a separate exercise. No pricing is published anywhere, which is a genuine obstacle when the natural comparison is a commodity probe with a visible price tag.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Soil Scout.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
Up to ten years for the Happi100 and up to twenty for the Hydra100, buried, with no battery replacement.
No. Sensors transmit to a base station through the soil, and only the base station uses a cellular modem.
No. It is a measurement and alerting system; controlling valves needs an integration with your irrigation controller through the API.
You dig it up. There is no remote service option, which is the trade-off for having nothing above ground to damage.

Softwr does not host reviews and shows no star rating for Soil Scout, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
