Smart Sprinkler Controller
Installation in Allen
The default Allen install: Rachio 3 Pro, wired correctly, with every zone calibrated for its actual head type, soil, and exposure. Optional Rachio Tempo weather station and flow meter for properties that want them. Hunter Hydrawise for estate-scale and multi-property setups.
A clean install plus per-zone calibration, not a box-on-the-wall
Wiring audit first
Before any new controller goes in we trace what is actually wired correctly. A controller swap that inherits a bad common wire or a stuck zone wire is going to look like a controller problem on day two. We test each zone from the existing terminal, document what's there, and fix what needs fixing before the new unit gets mounted.
Mount + power + transfer
Hard-wired install with the supplied transformer or an existing low-voltage feed. We label each zone wire as it goes onto the new terminal. Most Allen residential controllers (Hunter Pro-C, Rain Bird ESP-Me) come off the wall cleanly and the Rachio 3 Pro mounts in the same footprint.
Per-zone calibration in the app
This is where most DIY installs fall short. Every zone gets configured for its actual head type (spray vs rotor vs MP Rotator vs drip), soil type (Allen residential is mostly Blackland Prairie clay), sun exposure, slope, and plant type. That data drives the runtime math. A zone configured as "spray + clay + flat + turf" runs nothing like one configured as "rotor + clay + slope + shrub."
Cycle and soak built in
Rachio calculates cycle-and-soak automatically based on infiltration rate, slope, and head type. For Allen clay that means short cycles spaced out across the watering window so water actually absorbs instead of running off. You don't have to set it up manually like you would on a basic timer.
Weather Intelligence + restrictions
The controller pulls forecast and historical rain data and skips watering when it isn't needed. We also enter the local watering restrictions (NTMWD typically governs Allen) so the schedule stays compliant out of the box.
App walkthrough before we leave
You get the Rachio app on your phone, signed in to your controller, with the schedule running and the alerts configured. We walk through manual control, vacation mode, and how to check zone history. No mystery setup left for later.
The accessories worth adding (and the ones we will tell you to skip)
Rachio Tempo
A wireless, solar-powered weather station that mounts on the property. Measures rain, wind, temperature, and humidity at your address (not at DFW Airport or some other 15-mile-away station). Feeds that data straight into Weather Intelligence Plus for skip decisions and seasonal adjustment. Worth it if you've ever watched your sprinklers run during a thunderstorm because the regional forecast missed it.
Rachio Smart Hose Timer
For drip lines or hose-bib zones (commonly foundation soaker hoses), the Rachio Smart Hose Timer extends the same app and the same Weather Intelligence to off-system zones. Good for properties with foundation watering as a separate circuit from the main irrigation.
Flow Meter
Inline flow meter that detects abnormal flow conditions (broken lateral, sheared head, mainline break). The controller can auto-shut off the affected zone before water runs all night. Worth it on larger properties or any system that has had an unexplained spike on a water bill.
Hunter Hydrawise for larger properties
For estate-scale Allen properties (think Twin Creeks estates, Allen Ridge larger lots, or HOA common-area zones), the Hunter Hydrawise platform is the better fit. Same smart-controller approach as Rachio: weather-based watering, cycle-and-soak, app control. Different hardware ceiling and management interface.
The HC and HCC controllers expand up to 54 zones across modules. Multi-property management works better for owners running more than one site.
