Good investment _ saved my newly seed grass

“Being able to control the timer from my phone is a great time save. Setup is a bit quirky but once you have it configured it works well. Would buy again”

Works great. The app is awesome.

“These are great. I set up 5 of them to water my new lawn. I can easily control all the zones from the app. I set them up to run at staggered times each 5 minute at a time every hour throughout the day.”

Plan by garden area

Four garden jobs, one outside tap

Set a separate routine for the back-garden lawn, raised beds, greenhouse and patio pots before a weekend away or a longer holiday.

Back garden lawn · Raised beds & veg patch · Greenhouse · Patio pots & hanging baskets

Before ordering: check the outdoor tap thread, supplied adaptor, washer and water pressure. Test every outlet while you are at home.

Can I use it with a water butt?

Check the required water-pressure specification before ordering. Gravity-fed water butts may need a suitable pump and are not automatically compatible.

How should I prepare it for a holiday?

Run every zone while you are at home, check every hose and dripper for leaks, then review the schedule before travelling.

Can I use it during a hosepipe ban?

Restrictions and exemptions vary by water supplier and location. Check your supplier’s current rules before scheduling irrigation.

Why it suits a four-zone UK garden

Four independent watering zones

Outlets A–D can be scheduled separately, so a lawn, greenhouse, patio pots and allotment beds do not have to share one watering duration.

Indoor Wi-Fi, outdoor RF control

The gateway connects to 2.4 GHz Wi-Fi indoors and communicates with the outdoor timer by Sub-GHz RF. The manual states up to 500 m without obstacles; walls, distance and local interference can reduce real-world range.

App and manual operation

The timer works with the Tuya Smart or Smart Life app and also has buttons for the four zones. App functions shown in the manual include schedules, manual watering, misting, records and weather delay.

Installation and seasonal care

  1. Install Tuya Smart or Smart Life and connect the phone to 2.4 GHz Wi-Fi.
  2. Plug the gateway into a dry indoor socket near the router; the manual recommends 1–6 m for setup.
  3. Fit two new AA alkaline batteries in the timer, then pair the timer with the gateway in the app.
  4. Install the timer on a compatible 3/4-inch BSP outdoor tap and test every zone while you are at home.
  5. Before freezing conditions, remove the timer, take out the batteries, drain trapped water and store the unit dry indoors.

Frequently asked questions

Will RF work through every wall or to 500 metres?

No fixed household range can be promised. The manual’s 500 m figure is an unobstructed maximum. Building materials, distance and interference affect the actual connection.

Will it fit every UK outside tap?

No. The manual specifies a 3/4-inch threaded inlet. Confirm that your tap and any adaptor are compatible before buying.

Does it work with a 5 GHz-only Wi-Fi network?

No. The gateway setup requires 2.4 GHz Wi-Fi. The gateway must remain indoors and dry.

Can it run from a gravity-fed water butt?

Only if the supply reliably meets the stated 0.05 MPa minimum pressure. The timer does not include a pump and does not increase pressure.

What warranty does the manual state?

The booklet states a one-year warranty for device performance failures after sale. It excludes accessories and damage caused by unauthorised maintenance, misuse, abuse, accident, modification, incorrect use, force majeure or normal wear.
