The Best Smart Hose Timers and Sprinkler Controllers of 2026

It depends on the rules your water utility or local government sets: restrictions often limit sprinklers to certain days or hours, and drip irrigation is sometimes exempt. In France, for example, a ban on watering between 8 a.m. and 8 p.m. is common during droughts. Read your utility's notice before relying on an exemption, then set the controller to the permitted days and hours. A controller that skips runs after rain also helps you use less water once restrictions lift.

Multiply flow by time: a sprinkler delivering about 160 gallons an hour (600 L/h) uses about 53 gallons (200 L) in 20 minutes. Check your water bill for the rate, often per 1,000 gallons or per hundred cubic feet, and add the sewer charge if it's billed on the water you use. Drip lines use far less: 30 drippers at 0.5 gallon an hour (2 L/h) for one hour is about 16 gallons (60 L). A controller that skips runs after rain avoids wasted cycles.

For a garden hose or drip kit, a smart hose timer is enough; for in-ground sprinkler zones, choose a multi-zone controller that drives the solenoid valves. Pick Wi-Fi through a hub rather than Bluetooth alone, so you can change schedules away from home and use weather skips. Check that it works with your smart home platform, whether Alexa, Google Home or Apple Home, and that the outdoor faucet is within range. A soil moisture sensor is worth adding on sandy or clay soils.

Only if it's rated for low pressure or you add a pump, because a rain barrel delivers very little pressure by gravity. Many hose timers need a minimum pressure to open their valve, which a barrel sitting on the ground may not reach. Look for a gravity-fed timer, raise the barrel on a stand, or use a small submersible pump switched by the timer. Drip lines suit rain barrel water best; sprinklers need the pressure of your household water supply.

Bring it indoors before the first frost, because water left inside can freeze and crack the valve. Unscrew it, drain it, take the batteries out and store it somewhere dry. Drain hoses and drip lines too, and shut off and drain the outdoor faucet from its indoor shutoff valve if it has one, or put an insulated cover over it. In spring, put in fresh batteries and clean the inlet filter before reconnecting.
