Rain Bird HET200 2-Station Hose End Timer
Our score: 8.0/10 out of 102-zone · Batteries power · 15 psi minimum water pressure
A hose timer screws onto an outdoor faucet and turns the water on and off for a hose, a sprinkler or a drip kit. Plain timers are set with a dial and buttons; smart ones use an app over Bluetooth, which works only near the timer, or over Wi-Fi, which often needs a separate hub. Makers say to bring them indoors before the first frost.

A hose timer is the simplest way to automate a drip kit: see the best drip irrigation kits.
Set it at the faucet or by phone; add a hub later for Wi-Fi
Four outlets with their own schedules from one faucet
Rain skip, flow alerts and up to eight valves on one Wi-Fi hub

For Wi-Fi control away from home, often yes: Orbit's B-hyve XD and Rachio's timer use a hub, while Netro's Pixie 2 joins your Wi-Fi itself. Bluetooth control needs no hub but works only near the timer.
Usually a missing or worn washer, or a connection that went on crooked. Check the washer and its filter screen, then reconnect the timer straight and hand-tight.
Often, but some frost-free faucets have a vacuum breaker that drips while a timer holds the water on. If yours leaks from the top, check with the faucet maker.
Most models here take two AA or AAA batteries. Netro's Pixie 2 has a built-in battery charged by a small solar panel. Each product page lists the type.
Take it off the faucet before the first frost, remove the batteries and store it indoors. Orbit's warranty doesn't cover freeze damage.
Yes, with a multi-outlet timer: each outlet runs its own schedule, so a sprinkler and a drip kit can share one faucet. Orbit's B-hyve XD comes in a four-outlet version and Rain Bird's HET200 has two.
