Beat the Glare: Why I Motorized My Coolaroo 120 x 72
by Yuvien Royer on May 20 2025
It’s 3:00 PM on a Saturday. You’re comfortable on the couch, but the afternoon sun just hit the patio, turning your outdoor lounge into a convection oven. In the past, I would have to physically go outside, brave the heat, and manually crank a handle to drop the blinds. That friction often meant I just let the furniture bake. That changed when I installed the coolaroo outdoor roller shade 120 x 72 and decided to upgrade it from a standard manual fixture to a fully voice-controlled part of my smart home.
While Coolaroo is famous for durable HDPE fabric that breathes, the real magic happens when you pair this massive 10-foot shade with a retrofit tubular motor. Here is how I approached the installation, the retrofit process, and the daily reality of managing light control with voice commands.
Key Specs at a Glance
Because this is a hybrid setup (a manual shade converted to smart operation), understanding the physical and technical requirements is vital. Here is the breakdown of my specific configuration:
- Shade Dimensions: 120" W x 72" L (10ft width requires heavy-duty mounting).
- Fabric Material: High Density Polyethylene (HDPE) - blocks up to 90% UV.
- Retrofit Motor Type: 25mm or 35mm Tubular Motor (depending on tube diameter).
- Torque Requirement: Minimum 6Nm (due to the weighted bottom bar).
- Connectivity: Zigbee 3.0 (via dedicated Hub) or RF 433MHz bonded to Bond Bridge.
- Power Source: Rechargeable Li-ion battery with optional solar trickle charge.
Installation Realities: Handling the 10-Foot Span
Let’s be honest about the hardware first. The coolaroo 120 x 72 is substantial. Unlike interior blinds, this unit has significant weight to withstand wind. Installing the brackets requires precision because the tolerance for the idle end and the motor end is tight—usually less than a quarter-inch margin of error.
If you are mounting this into stucco or brick, a hammer drill is mandatory. I found that the included screws were adequate for wood, but I swapped them for 3-inch structural screws for peace of mind. Since this is an exterior install, leveling is critical; if the brackets aren't perfectly level, the fabric will "cone" or telescope to one side as it rolls up, eventually jamming the mechanism.
Power & Motor Retrofit Options
Out of the box, the coolaroo shades 120 x 72 operate via a hand crank. To integrate this into a smart ecosystem, you have two primary paths:
1. The Tubular Motor Swap
This is the cleaner, professional route. I removed the manual crank mechanism from the roller tube and inserted a battery-powered tubular motor. For a shade of this width, you cannot use a weak motor. I recommend a motor with at least 6Nm of torque. The noise level on these is surprisingly low, generally hovering around 40dB—roughly the hum of a refrigerator.
2. The Chain Driver (Not Recommended Here)
While external chain drivers (like the Aqara E1) are popular for indoor blinds, Coolaroo exterior shades use a crank loop, not a beaded chain. Therefore, the tubular motor insert is the only viable way to get true smart functionality.
Ecosystem Integration: Zigbee vs. RF
Once the motor was inside the tube, getting it to talk to Alexa was the next step. I opted for a Zigbee motor because it reports battery status back to the hub. If you choose a cheaper RF (Radio Frequency) motor, you will need a bridge like the Bond Home or Broadlink RM4 Pro.
With the Zigbee setup, I created a routine called "Afternoon Shield." When the outdoor temperature sensor hits 85 degrees, the shade lowers to 80%. This isn't just cool tech; it actively lowers the cooling load on my living room by shading the sliding glass doors before the heat enters the house.
Living with coolaroo outdoor roller shade 120 x 72: Day-to-Day Reality
After three months of daily use, I’ve noticed a few nuances that spec sheets don't tell you. First, there is the issue of wind. Even though the shade is heavy, a 10-foot wide sail catches a lot of air. I had to install the tie-down bungees at the bottom. This creates a friction point for smart operation: I cannot lower the shade remotely if I forgot to unhook the bungees the night before.
Another detail is the "settling" noise. When I issue a voice command to lower the shade, the motor engages instantly, but because the fabric is heavy duty, there is a distinct crackle sound as the HDPE layers separate after being rolled up tight in the sun. It’s not a defect, just a characteristic of the material. Also, regarding the battery: with one up/down cycle per day, the battery dropped only 15% in 90 days, meaning I’ll likely only need to charge it twice a year.
Conclusion
The coolaroo outdoor roller shade 120 x 72 is a fantastic physical product on its own, offering robust UV protection. However, retrofitting it with a smart motor turns it into a genuine asset for climate control and convenience. It requires a bit of DIY confidence to install the motor, but the ability to block the sun without leaving your chair is an upgrade I can't undo.
Frequently Asked Questions
How do I charge the battery if the shade is mounted high up?
Most retrofit motors come with a long magnetic charging cable (often 6-10 feet). Alternatively, you can mount a small solar panel on the top valance to keep the battery topped off indefinitely.
Can I still use the manual crank if the battery dies?
Generally, no. Once you replace the internal mechanism with a motor, you lose the manual crank capability unless you buy a specific "manual override" motor, which is rarer and more expensive.
Does this work with Google Home?
Yes, provided your motor interface (Hub or Bridge) supports Google Home. Most Zigbee hubs and the Bond Bridge expose the shade to Google Home as a standard blind device.
