Rachio Smart Hose Timer Review: My Favorite Recent Purchase

One of the only recent tech purchases I've genuinely enjoyed is the Rachio Smart Hose Timer. And it's a product I had no intention of reviewing when I bought it.

My new home came with an ancient underground sprinkler system that barely worked, then it got torn up during landscaping. Someday I'll fix it, because an in-ground system costs less to run with its own separate city water line.

But in the meantime, I was stuck manually turning my sprinklers on in the morning, setting a timer on my watch, then going back out to shut them off.

Now, I've got four tripod sprinklers (three in the back yard, one in the front) and four Rachio timers that automate the whole thing with zero brainpower. I've actually bought seven of these timers total, but more on that in the longevity section.

Hardware & Setup

Each Rachio timer ships with its own hub. You can place the hub anywhere that has solid Wi-Fi and is close enough to reach your outdoor spigots. My house is a decent size; one centrally located hub covers all four hose bibs, which is a huge win because the last thing I wanted was multiple hubs hogging outlet and countertop space.

Setup was standard 2.4 GHz smart-device pain: I had to temporarily disable my router's 5 GHz band so the timer could join the 2.4 GHz network. Annoying but common, and once it's paired you're golden.

A heads up: these timers only work if you leave your faucet open 24/7. That keeps the line pressurized, but water won't flow until the timer opens the valve. You can control how much water pressure you get by not opening the spigot all the way, but I leave mine fully open. The downside is that if your spigot leaks even a little, you will waste water. One of my spigots drips constantly. A plumber could fix it, but the leak is maybe $0.50 a month, so it's not worth it to me.

Pricing

If you're buying your first timer, you need the hub + timer combo, which runs about $100. After that, you only need one hub for your whole setup (it supports up to eight timers), so additional timers are around $70 each. Amazon Warehouse often has like-new or very good condition units for even less if you don't mind open-box. I've bought a few of mine that way.

For the sprinklers themselves, I use basic $35 tripod sprinklers from Amazon. My full four-zone setup cost about $420 all in: one hub + timer combo, three additional timers, and four sprinklers. That's a fraction of the thousands it would cost to resurrect my in-ground system.

Inside the Rachio App

Smarter Scheduling

Weather skip: The timer won't run if rain is in the forecast. You can set a threshold from 1/16" to 3/4".

It shows local weather, but I wish you could see the exact projected rainfall each day, which would make adjustments easier.

If you've got more than one valve, you can run them simultaneously or staggered. I run mine simultaneously, pre-sunrise, but only if the forecast says we're getting less than 1/2" of rain.

Manual Control

For manual control, press the physical timer button for one second and it launches a Quick Run using your preset duration. I started with 20 minutes to match my daily schedule. The problem shows up when I'm washing the car, hosing down the deck, or powering the kids' splash pad: the water shuts off mid-task.

What I'd like to see: A single long press that keeps the water flowing indefinitely, and a double press for the timed run. Every manual run still shows up in the event log, which makes sense for irrigation but it messes up your data when the hose is being used for chores. A toggle to hide those sessions would keep the log clean.

The best workaround, which I didn’t think of until a few months after my original review, is a two-way hose splitter. One side connects to the Rachio and your sprinkler, the other side connects to a regular hose for car washing, the splash pad, or whatever else. That way your recreation hose is always available without the timer cutting you off. A splitter is about $10, but you’ll also need a second hose if you don’t already have one, which can run $20-$40 depending on length. Still way less annoying than fighting the timer every time the kids want to play in the water.

Event Log & Data Wishes

You can see a list of every run, which is great, but the layout could use work. I want to see which hose ran and for how long without an extra tap, and I want cumulative weekly runtime for each timer. There's a workaround using an IFTTT recipe that dumps your data into a Google spreadsheet, but that should be built in.

Day-to-Day Experience

Reliability: Solid. Once connected, nothing has dropped off.

Range: One centrally located hub covers all four of my exterior spigots in a multi-story house. Rachio says up to eight timers can run off a single hub. Your mileage will vary depending on spigot placement, Wi-Fi strength, hub location, and the size of your home.

Battery life: Each timer uses two AA batteries. During my first season, the batteries lasted the full watering season and still showed full in the app. I'd expect at least a year of use before needing replacements. That said, if you're storing them for winter, pull the batteries out so you're not wasting them (more on that below).

Integrations: Rachio works with Alexa and Google Assistant. It used to support Apple HomeKit, but that's been dropped. After you set a watering schedule there's not much reason to use a voice assistant, and running automations outside the Rachio app would skip the built-in rain data. Most people will never need deeper smart home integration.

Longevity & Winter Storage

This is where I have to share an expensive lesson.

When I fired up my sprinklers this spring, three of my four Rachios were leaking through the battery compartment. When I took them apart, the plastic housing where the hose connects had cracked. This was my fault. I turned off the water for the winter, but I left the timers attached to the spigots outside. They froze, the water inside expanded, and the plastic cracked.

I tried patching them with JB Weld plastic putty, but I couldn't get a reliable seal. Ended up buying three new timers this spring, which is how I've now gone through seven total.

Here's what's frustrating: I didn't see anything in the instructions or packaging warning you to bring these inside for winter. It's probably common sense, but I wasn't thinking about it since our winters aren't that cold. A few things I wish Rachio would do:

Send a notification when it's time to winterize. If the timer hasn't been used in a certain number of days and temperatures are dropping, ping the app and remind people to disconnect them and bring them inside. It would also be a good reminder to pull the batteries.

Use metal instead of plastic for the hose connection. That's where every single one of mine cracked. A brass or stainless fitting would survive a freeze way better than the plastic they're using now.

Worth noting: even with cracked housings, all four timers still connected to the app and could be controlled from my phone. The electronics survived, it was purely the plumbing side that failed.

My winterization routine going forward: Once the watering season ends, I'll disconnect all the timers from the spigots, drain any remaining water, pull the batteries, and put them inside. Takes five minutes and saves $70-$100 per timer.

Bottom Line

For about $420 all in (four tripod sprinklers plus four Rachio timers with one hub), I replaced a daily chore with a system that runs itself. The Rachio Smart Hose Timer is the simplest, cheapest way to keep a lawn alive without thinking about it. And when I'm ready to resurrect my in-ground system someday, I can sell the smart timers and recoup some of the dough.

Would I recommend it? Definitely. Just be prepared for some Wi-Fi funkiness during setup and a user interface that could use some love. I'd love to see better event summaries, cumulative usage data, better rainfall details, and a winterization reminder in the app. But those are nice-to-haves, not deal breakers.

The big warning: bring them inside for winter. Even a mild freeze can crack the plastic housing and you'll be buying replacements. I learned that the hard way.
