SwitchBot Roller Shade: measurements, installation and Canadian buying guide
Roller Shade is a complete motorized window covering rather than a motor added to an existing curtain. The price shown on RoboStead is for one grey Size S unit, 58–80 cm wide. Size, colour, solar-panel bundles and installation geometry can all change the real order total.

A polished choice when the opening matches a published size and the mounting surface meets the depth, coverage and strength rules. Inside mounting needs at least 7 cm of depth—or 9 cm for full recess—and leaves about a 25 mm light gap per side. Outside mounting gives better blackout coverage when the shade is about 10 cm wider than the window.

Good fit
This product may fit if…
- You want a complete coordinated motor, tube and fabric rather than adapting an existing blind.
- The exact opening falls within a published width and the chosen mount has enough depth and structural support.
- You accept the expected side gaps for inside mounting or have room for an outside shade 10 cm wider than the window.
- The room stays within the published temperature range and charging or optional solar-panel access is practical.
Stop before buying
Do not order yet if…
- You measured only the glass and not the actual inside opening, trim, handle, crank and bracket locations.
- You require full blackout from an inside mount but have not accounted for about 25 mm of light gap on each side.
- The wall or ceiling material cannot safely hold the load with appropriate fasteners, or the mounting surface is under 4 cm thick.
- The location falls below 0°C or you are counting on a custom replacement fabric not recommended by SwitchBot.
Installation
Five-step verification plan
- 1
Decide inside or outside mounting first, then measure the opening at the top, middle and bottom and use the limiting dimension.
- 2
Mark the 82 × 72 mm headrail envelope, bracket locations, handle clearance and the complete 2.2 m fabric drop.
- 3
For an inside mount, confirm 7 cm depth and expected side gaps; for an outside mount, plan about 5 cm overlap per side.
- 4
Verify the substrate, select wall- or ceiling-appropriate fasteners and confirm at least 10 kg of safe support before drilling.
- 5
Install and calibrate the upper and lower limits locally; test obstructions, group movement and charging access before adding schedules or Hub 2.
After installation
What ownership requires
- The eight-month battery figure comes from a 25°C, 1.85 m, 4 kg, once-up-and-down-per-day test; heavier or more frequent use changes the result.
- Keep the fabric clean, the travel path unobstructed and the upper and lower limits recalibrated after physical changes.
- If adding the optional solar panel, verify useful light exposure and cable routing instead of assuming it eliminates charging in every window.
FAQ
Questions before buying
Why is there a light gap with inside mounting?
The fabric is 4.4 cm narrower than the complete device, and SwitchBot advises allowing about 25 mm per side. For stronger blackout coverage, an outside mount roughly 10 cm wider than the window is the safer published approach.
Does Roller Shade require a hub?
Basic Bluetooth operation does not make a hub mandatory. The current Canadian product page specifies the separately sold Hub 2 for Matter and Apple HomeKit. Confirm the exact platform and hub before ordering them together.
Does the RoboStead price cover every size and bundle?
No. RoboStead displays the exact Size S, grey, one-unit SKU. Wider sizes, other colours and solar-panel bundles can have different Canadian and US prices; recheck the selected variant before checkout.
