LinkTap G2S Smart Hose Timer + Gateway (TP-2BS, GW-02)
Best for filling a pool: water by volume or for up to 23 h 59 min, with a flow meter and a high-flow shutoff — LinkTap's G2S is a hose timer paired with a gateway, scheduled from LinkTap's app: runs from 1 minute to 23 hours 59 minutes, up to 100 a day, and LinkTap says every watering mode supports "Watering by Duration or Volume", so a fill can stop at a set amount of water instead of a set time. It measures flow (2 to 50 litres a minute, ±5%, by its spec page), LinkTap says it will alert you to "valve failures", and it can shut the water off when an unusually high flow is detected. It is sold by LinkTap's own US store, and owners give it 4.5★ across 1,808, 8% at one or two stars. The catch is the one most timers here carry: an owner reports it "failed open just over a year" in and "Water ran for two weeks at my vacation home in Florida" without an alert, and 3 of its 10 newest written critical reviews describe a valve stuck open. Only 2 were left in stock on 2026-10-23.

Pros
- One run lasts up to 23 hours 59 minutes, long enough for a day-long fill, with up to 100 runs a day
- Waters by volume as well as by time: LinkTap says every mode supports "Watering by Duration or Volume", so a pool top-off can stop at a set amount of water
- A flow meter (2 to 50 litres a minute, ±5%, by LinkTap's spec page; its timer page prints other ranges) and an optional automatic shutoff "when an unusually high flow is detected"
- LinkTap says it alerts you to "valve failures" by push and by email, and to two more contacts you choose
- Sold and shipped through Amazon by LinkTap-US, the maker; 8% of its ratings sit at one or two stars
- LinkTap says that if the battery runs low the timer "will automatically shut off the valve to prevent water waste", and it rates the G2S from 3 psi
- If the power or network drops, LinkTap says a run in progress "will end as usual"
Cons
- The catch: 3 of its 10 newest written critical reviews describe a valve stuck open, one for "two weeks at my vacation home in Florida" with no alert from its flow sensor; a smart timer is not a backstop
- 23 h 59 min is still its longest single run; a fill that needs longer needs a second run
- Only 2 were left in stock on 2026-10-23, from its one seller
- Bulky on a low spigot, and one owner notes the gateway "needs to be physically connected to your router"; frost damage is excluded from the warranty
A valve that sticks open, and a sensor that did not say so. The newest critical reviews say it "failed open just over a year of use. Water ran for two weeks at my vacation home in Florida", that one "got stuck open for a week", and that in another "Water flows through it whether it’s on or off"; two died after a year or two and a half seasons, two gave barely a trickle, and one's threads were "soft plastic".
Of its 10 newest written critical reviews (September 27, 2024 to August 21, 2026), 3 describe a valve stuck open (one not a verified purchase), 2 a timer dead after one to two and a half seasons and 2 weak flow, of 64 written critical reviews; the histogram puts 6% of 1,808 ratings at one star (2026-10-23) · critical reviews read 2026-10-23
“Setup was easy. I get reliable notifications (not the case with the Orbit). The app isn't going to win any awards for sleek/cool design, but it's intuitive and functional, and that's what is important to me.”— ijp, Amazon · Verified owner
