Pricing
You pay for the sensors you have switched on, and nothing else. There is no account fee, no volume tier, no feature held back for a plan above yours, and no minimum term. The sensor itself is a separate one-time purchase, so the subscription is only ever the software.

The one to pick if you are still working out how many sensors your yard actually needs. Add and remove them month to month and the invoice follows.

$49 per sensor / year
The same product for about two months less money. Worth it once a sensor has earned its place in the ground and you know it is staying there.
Start annualThe sensor is a one-time purchase, separate from the subscription and charged once. Price to confirm — it is not printed here yet because it is not settled, and we would rather leave the field empty than publish a number we would have to walk back. You order one from your dashboard after signing up; if you already own a compatible sensor, claim it and buy nothing.
What you get
The agronomy is the product. Charging extra for it would be charging extra for the point, so there is nothing on this list that arrives only at a higher tier — because there is no higher tier.
Fig. 01 — The full inventory. Fourteen things, one price. If a feature ever does get held back for a tier above yours, this page is the first place it will be admitted.
Do the arithmetic
Most yards need one or two. Four is a big property with genuinely different ground in each corner. Here is every figure, multiplied out, with nothing rounded in our favour.
A front lawn on a single irrigation zone.
Effective $4.08 per sensor per month on the annual term, whichever row you are on.
Front and back, watered on different zones.
Effective $4.08 per sensor per month on the annual term, whichever row you are on.
Two zones, a shady strip and a new-seed patch.
Effective $4.08 per sensor per month on the annual term, whichever row you are on.
Four sensors cost four times one sensor. There is no volume break, and we are not going to draw one on a chart to make the big number look generous. The only discount here is the annual term, and it is the same 18% whether you run one sensor or ten.
Fig. 02 — Subscription only. The one-time cost of the sensors themselves is not in these figures, and is not settled yet.
Billing, in plain English
There is no plan to choose per sensor and no second invoice to reconcile. Your account has exactly one subscription with one line on it, and the number on that line is a count of the sensors currently switched on. Everything below follows from that one fact.
Scroll the figure sideways
One sensor active, so the quantity is 1 and the invoice is $4.99. Billed in advance for the month ahead.
The quantity goes to 2 straight away and the charge is prorated — you pay for the half-month the new sensor is actually running, about $2.50, and the full rate from April.
The quantity comes back to 1. Nothing is credited for the eleven days left in May — and equally, that sensor is not cut off. It keeps reporting to the end of the period you paid for.
One sensor active, so the invoice is $4.99 again. No call, no form, no confirmation email to chase.
Your last sensor
Cancels at period end
Switch off the last one and the subscription is set to cancel when the current period runs out. Nothing renews and you are not charged again.
A failed payment
New readings stop, history stays
The ingest endpoint turns the sensor away, but nothing already stored is touched. Sign in, read it, export it.
A suspended sensor
Still counted
Suspending is not the same as deactivating — the slot and the history are still being held, so it stays in the quantity. Deactivate it to stop paying for it.
The hardware
Its own one-time receipt
Charged once, on a separate invoice. It never touches the subscription and it never renews.
Fig. 03 — The quantity on your subscription is derived, not typed: it is a count of the sensors on your account that are active or suspended, and a nightly job re-checks it against Stripe so the two cannot quietly drift apart.
Before you commit
Where the honest answer is “no”, it says no. The rest of the thirty-one answers cover sensors, connectivity, accuracy and privacy.
$4.99 per sensor per month, or $49 per sensor per year. That is the software: every reading stored, every one of the eight tools, alerts, export and the dashboard. Every feature is included at both tiers — there is no plan where the useful tools are held back. The sensor itself is a separate one-time purchase.
Per sensor. One account can hold as many as you like, and you still have exactly one subscription — its quantity is simply how many sensors are switched on. There is no per-account fee on top.
The quantity goes up the moment the sensor is activated, and the charge is prorated: you pay for the part of the current period the new sensor is actually running, then the full rate from the next invoice. Nothing is backdated.
The quantity comes down and the next invoice is smaller. Nothing is credited back for the days you already paid for, and the sensor keeps reporting to the end of the period you bought — you are not cut off in the middle of a month you have paid for.
The subscription is set to cancel at the end of the current period. Nothing renews and you are not charged again. Signing in, reading your history and exporting it all keep working.
No. Four sensors cost exactly four times one sensor, and we are not going to invent a tier to make that look like a deal. The only saving on this page is paying yearly, which is about 18% — roughly two months.
Yes, but not by yourself yet. The billing portal covers your payment method, your invoices and cancellation; changing the term is a change we make on the account, so write to us and we will move you at your next renewal.
No. Anything that can reach us over HTTPS, MQTT or LoRaWAN can report in, and claiming a device hands you the ingest endpoint, the request-signing snippet, an MQTT example and the full Things Network payload formatter. There is no proprietary hub, and there never will be.
The sensor stops being able to send new readings — the ingest endpoint answers 402 and the device buffers or drops. Nothing already stored is deleted: you can still sign in, read every reading you have and export the lot as CSV.
At any time, from the billing portal, with no phone call and no retention script. You can also deactivate a single sensor instead of cancelling everything, which drops the quantity by one and leaves the rest running.
Yes. If you have one, the checkout page has a field for it before you confirm.
Put one in the ground
One is the honest starting point for almost every lawn: stake it in the corner that browns first and you will know within a day how fast your soil really dries. If a second one is not obviously worth $4.99 a month to you, do not buy one.
Send us your layout and we will tell you honestly how many sensors it wants — including when the answer is one.
