Woox R2603 review

Wi-Fi without a gateway, IP65 with double silicone seals, twenty schedules, a rain delay and offline alerts.

The bottom line The only timer here with a published IP rating — IP65, with double silicone seals on the battery compartment — and the only connected one that needs no hub. Twenty independent schedules, two watering modes including a soak cycle, a 1 to 30 day rain delay, and a push alert if the valve fails to open.

What the maker prints on its own page

No gateway required: the timer connects directly to a 2.4 GHz home network so watering can be controlled remotely from an app. Optimised power management is stated to keep the device running for several growing seasons on one set of standard batteries. Double silicone sealing rings and an IP65 housing are stated to keep rain and moisture out. Two watering modes are offered — scheduled watering, and cyclic soaking for gradual delivery that prevents soil run-off and suits drip watering of pots — with up to 20 independent schedules. A rain delay of 1 to 30 days pauses schedules according to the weather, and a manual mode gives immediate water without interrupting the presets. Daily watering logs and round-the-clock status monitoring are provided, with an immediate push notification if the device goes offline or the valve fails to open or close as scheduled. It works with Alexa and Google Assistant.

The only IP code on this shelf

IP65, with double silicone rings on the battery compartment.

Five timers here and one rating. That is the specification that matters most on this shelf, because the way these devices die is water getting into the electronics or the batteries after a summer of rain running down the tap.

An IP code is a defined test rather than the word “waterproof”: the first digit dust-tight, the second protection against water jets. Both were measured against an apparatus.

No hub

The other connected timer on this shelf needs a Zigbee gateway. This one joins a 2.4 GHz network directly.

That is one box instead of two, and it is also a constraint: the tap has to be within range of the house Wi-Fi, and 2.4 GHz reaches further through walls than 5 GHz does but not indefinitely. A tap at the end of a long garden may not be reachable.

The alert

“Push notification if the device goes offline or the valve does not open or close as scheduled.”

An automatic watering system fails silently. The batteries go, or a valve sticks, or the network drops, and the only symptom is a lawn that is browner than it should be a fortnight later.

Being told is the difference between a nuisance and a dead lawn, and this is the only device here that does it.

Cyclic soaking

Short bursts with pauses instead of one long run.

On a slope, on compacted ground, or on a pot, a continuous flow runs off before it soaks in. Splitting the same volume into intervals puts it where the roots are. It is the single most useful watering mode a timer can offer and only one listing here has it.

What is missing

The connection thread and any pressure range. The second matters: a timer meant for a mains tap and a timer that will open on a gravity-fed butt are different devices, and this listing does not say which it is.

Availability

From 42 € to 50 €, that being the spread across the German, French, Italian and Spanish Amazon stores on the day of the survey.

Listed and unsold: the British Amazon catalogue holds the reference with nobody behind it.

Nothing came back from the American Amazon store at all; the buy button there runs a search rather than opening an empty page.

The declared figures, and the point they stop at

Strengths

  • An IP65 rating with double silicone seals, published — the only IP code on this shelf
  • Wi-Fi with no hub, so there is one box rather than two
  • A push alert if the device goes offline or the valve does not open as scheduled

Compromises

  • No connection thread and no pressure range published
  • 2.4 GHz only, so the tap has to be within reach of the house network
  • Connected, and therefore dependent on an app and a service

What this machine usually gets asked

What does IP65 actually cover?

The first digit is dust-tight; the second is protection against water jets from a nozzle of a defined bore. That is a substantial rating for a garden device and it is a defined test rather than the word “waterproof”. The IP code has its own page in the standards section here.

What is cyclic soaking?

Water delivered in short bursts with pauses, so it soaks in rather than running off. On a slope or on compacted ground, watering in one long run puts most of it in the gutter, and this mode is the answer.

What is the alert worth?

More than it sounds. The way an automatic timer fails is silently — flat batteries, a jammed valve, a lost connection — and the way you find out is a brown lawn two weeks later. A push notification when the valve does not open is the feature that turns that into a same-day fix.

Who this one is for

A tap within Wi-Fi range, where the watering should be checkable from somewhere else
