Summer heat strains water budgets and traps pollutants indoors. We tested the smart sprinkler controllers, air purifiers, and display hubs that actually solve those problems — here are the ones worth buying.
Eight hyperlocal weather feeds and ~32% water savings make this the smartest sprinkler controller for drought-season watering — if your Wi-Fi reaches the install point.
Weatherproof housing, dual-band Wi-Fi, and a long-range radio keep it running where Rachio's signal drops — ideal for outdoor and detached-garage installs.
CNET's #1 air purifier, specifically ranked best for smoke, allergies, and dust — the top choice when wildfire smoke is your primary concern.
Summer in a hot climate is a two-front problem. Outdoors, drought pushes water bills skyward just as lawns need it most. Indoors, closed windows trap wildfire smoke, allergens, and stale air while your AC works overtime. The right smart home devices automate both pain points — and a smart display hub ties the whole routine together.
We focused on three categories that directly address summer-specific challenges: smart sprinkler controllers that adapt to weather, smart air purifiers that clear smoke and allergens, and a smart display hub to coordinate climate routines. Here's what we found.
A smart sprinkler controller is the single highest-ROI upgrade for a hot-climate home. Instead of running on a dumb timer, these devices check hyperlocal weather data and skip watering cycles before rain or after a cool spell — saving water when every gallon counts.
Rachio 3 is the smarter waterer. It pulls from eight hyperlocal weather sources, averages bigger water savings of roughly 32%, and runs the cleanest app with the widest smart-home support.3 If your Wi-Fi signal reaches your garage or outdoor install point, it's the clear top pick.
Orbit B-hyve is the tougher box. Dual-band Wi-Fi, a long-range radio, a built-in weatherproof housing, and physical buttons keep it running where the Rachio struggles.3 For detached garages, exposed outdoor mounts, or homes with weak Wi-Fi at the controller location, the B-hyve is the rugged value alternative.
When wildfire smoke seeps in and windows stay shut to keep heat out, indoor air quality plummets. Consumer Reports notes that nearly half of the U.S. is experiencing drought, raising the prospect of an early and active wildfire season — and that the best HEPA-filter air purifiers can reduce particle concentrations by as much as 85 percent.2 Large purifiers rated for rooms bigger than 350 square feet tend to be better at removing smoke.2
Blueair 311i Max earned CNET's #1 ranking as best overall air purifier, and specifically best for smoke, allergies, and dust.4 If wildfire smoke is your primary concern, this is the one to get.
Levoit Vital 200S is the value pick. Recommended by Popular Mechanics as best for pets and by This Old House, it delivers strong smoke, pet, and allergen filtration for large rooms at a lower price point.4 Blueair outranks Levoit by one position in meta rankings, but the Levoit's price-to-performance ratio makes it the smarter buy for budget-conscious households.4
A smart display hub is the glue that turns individual devices into a coordinated climate system. Lifehacker recommends creating conditional rules — for example, "IF the room temperature hits 74, THEN turn on the smart plug connected to your fan" — and limiting sunlight through windows so AC doesn't work as hard.1 A hub with built-in protocol support makes those automations reliable.
Amazon Echo Show 8 (3rd Gen) is the clear leader for home automation. It includes a built-in smart home hub with Matter and Zigbee support, advanced Alexa routines, and a visual smart home dashboard.5 The Google Nest Hub Max offers Thread support only, with no built-in Zigbee hub — a meaningful gap if you're building climate routines that span multiple device protocols.5
For summer specifically, the Echo Show 8 can coordinate thermostat schedules, trigger fans and smart blinds based on temperature, and manage sprinkler timing — all from a single dashboard or voice command.
Hot-climate summer living comes down to two questions: Are you watering efficiently? Is your indoor air clean? A Rachio 3 (or Orbit B-hyve for tough installs) answers the first. A Blueair 311i Max (or Levoit Vital 200S for value) answers the second. And an Echo Show 8 ties it all together with automations that cut cooling costs without you lifting a finger.
