Somfy vs. Hunter Douglas vs. Lutron vs. Alta — Motorization Compared
Not all motorized shades are created equal. We install and service every major motorization platform. Here's an honest comparison to help you choose the right technology for your San Diego home.
Why the Motor Brand Matters More Than the Shade Brand
When you buy motorized window treatments, you're really making two decisions: which shade looks best, and which motor technology powers it. The motor determines how long your shades last, how easy they are to repair, and how well they integrate with your smart home.
After 18+ years installing and repairing motorized shades across San Diego, we've worked with every platform on the market. Below is our honest, experience-based comparison of the four motorization technologies we recommend — and when we choose one over another.
Somfy
1969 — Cluses, France
The Motor Inside Almost Every Shade
Somfy is the world's largest manufacturer of motors for window coverings. They don't sell shades directly — they make the motors inside them. When you buy motorized shades from Graber, Norman, Springs Window Fashions, or most custom fabricators, there's a Somfy motor doing the work.
Key Strengths
- Powers 50+ shade brands worldwide — you're never locked into one manufacturer
- RTS and io-homecontrol protocols are industry standards
- Parts and remotes available for 15+ years after purchase
- Any Somfy-certified technician can service them — not brand-dependent
- TaHoma hub integrates with Alexa, Google Home, Apple HomeKit, SmartThings
- Quietest motor in its class (~35 dB)
Ideal For
Homeowners who want the best long-term value, repairability, and brand flexibility. Our default recommendation for most San Diego homes.

Lutron invented the solid-state dimmer in 1961 and has been the leader in smart lighting and shading ever since. Their Serena shades integrate with Caseta, RadioRA 3, and HomeWorks ecosystems — making them the preferred choice for whole-home automation where shades and lights work together seamlessly.

Alta Window Fashions

Hunter Douglas Quality at a Competitive Price
Alta is Hunter Douglas's value-oriented brand, created to compete with mid-tier manufacturers like Norman and Graber. Alta offers quality window coverings with motorization options at prices 20–30% below mainline Hunter Douglas products. Same parent company engineering, more accessible price point.

When We Recommend Each Brand
There's no single “best” motorization brand — it depends on your home, your budget, and how you want to control your shades.
Most San Diego Homes
→ Somfy
Best value, universal parts, longest repair window. Works with any shade brand, so you can switch styles without changing motors. Our default recommendation.
Already Using Lutron Caseta Switches
→ Lutron Serena
If you already have Caseta dimmers and switches, adding Serena shades creates a unified system. One app, one remote (Pico), and scenes that coordinate lights + shades effortlessly.
Statement Rooms & Designer Homes
→ Hunter Douglas PowerView
For living rooms, dining rooms, and spaces where aesthetics are paramount. Silhouette, Pirouette, and Luminette are genuinely unique products that competitors can't replicate.
Investment Properties & Multi-Room Projects
→ Alta (by Hunter Douglas)
When you're furnishing 10+ windows, Alta delivers trusted quality at a lower per-window cost. Hunter Douglas engineering without the premium price tag.
Commercial & Large-Scale Projects
→ Somfy or Lutron (project-dependent)
Somfy for cost-effective large-scale deployments. Lutron for buildings that need integration with commercial lighting and HVAC systems (via BACnet/DALI).
Why We Default to Somfy — But Not Always
After installing thousands of motorized shades across San Diego, we've learned that repairability is the most undervalued factor in the purchase decision. A shade that looks beautiful but can't be repaired in 5 years is a bad investment.
That's why Somfy is our default recommendation for most homes. Their universal motor platform means your shades can be serviced by any certified technician, parts are available for 15+ years, and you're never locked into a single shade manufacturer.
But Somfy isn't always the answer. If you're already invested in a Lutron Caseta lighting system, Serena shades create a seamless experience that Somfy can't match. If you want Silhouette or Pirouette shadings — products genuinely unlike anything else on the market — Hunter Douglas PowerView is the only option. And if you're furnishing 10+ windows on a budget, Alta delivers trusted quality at a lower price point.
We carry and install all four. During your free in-home consultation, we'll assess your windows, discuss your smart home setup, and recommend the motorization platform that makes the most sense for your situation — not the one with the highest margin.

Motorization Brand FAQ
Common questions about choosing between Somfy, Hunter Douglas, Lutron, and Alta motorization.
Which motorization brand is best for my home?
It depends on your priorities. For the broadest compatibility and best repairability, we recommend Somfy — their motors power 50+ shade brands and parts are available for 15+ years. For a fully integrated smart home with lighting control, Lutron is unmatched. For premium aesthetics and innovative shading designs, Hunter Douglas PowerView is excellent. During your free consultation, we'll recommend the best fit based on your home, budget, and smart home setup.
Can I mix motorization brands in the same house?
Yes, and we often do. For example, you might use Lutron Serena shades in the living room (tied into a Caseta lighting system) and Somfy-powered roller shades in the bedrooms for cost efficiency. Each brand's app and hub work independently. The only consideration is voice assistants — Alexa, Google Home, and Apple HomeKit can control all major brands from one command.
What is Alta Window Fashions and how does it compare to Hunter Douglas?
Alta is Hunter Douglas's value-oriented brand, launched to compete with mid-range manufacturers. Alta products use quality components and offer solid warranties, but at a lower price point than mainline Hunter Douglas. Think of it as Toyota vs. Lexus — same parent company, similar engineering, different trim levels. Alta motorized shades use proven motor technology and integrate with smart home systems.
How long do motorized shade motors last by brand?
Somfy motors are rated for 10–15+ years and we've serviced units running over 20 years. Lutron motors carry a similar lifespan with their 8-year warranty. Hunter Douglas PowerView Gen 3 motors are relatively new but built on proven engineering with a 5-year motor warranty. Generic imported motors typically last only 3–7 years. Motor brand is the single most important factor in longevity.
Do Somfy motors work with Alexa and Google Home?
Yes. The Somfy TaHoma hub connects Somfy RTS and io motors to Alexa, Google Home, Apple HomeKit (via HomeKit bridge), Samsung SmartThings, and IFTTT. You can also use the Somfy myLink app for basic scheduling without a smart speaker. Lutron has native Alexa, Google, and HomeKit support built into Caseta and RadioRA systems.
Is Lutron only for new construction?
No. Lutron Serena shades with the Caseta bridge are designed for retrofit — no new wiring needed. Battery-powered Serena shades install like any other window treatment. The Caseta Smart Bridge plugs into your router and covers up to 75 devices. Hardwired Lutron (RadioRA 3, HomeWorks) is ideal for new construction or major remodels, but it's not required.
Why does Royal Window Coverings recommend Somfy as the default?
Three reasons: (1) Universal compatibility — Somfy motors work inside shades from dozens of brands, so you're never locked in. (2) Repairability — standardized parts mean any certified technician can service them, even 15 years later. (3) Cost — Somfy-powered shades are typically 20–30% less expensive than proprietary systems like Lutron or Hunter Douglas, without sacrificing quality or smart home features.
What happens if a motorization brand discontinues a product?
This is where brand choice matters most. Somfy's universal motor platform means even if your shade brand disappears, the motor can still be serviced with standard Somfy parts. Hunter Douglas has a 100+ year track record and extensive parts inventory. Lutron has been in business since 1961. Generic or imported motors from unknown brands often become unrepairable when the manufacturer exits the market.
