A retrofit curtain motor needs to fit the actual rod or rail, not simply match the curtain color. Identify the track system and movement before comparing app features or bundle prices.
Identify the support system
SwitchBot’s compatibility guide separates rod and rail configurations and provides relevant measurements. Use the exact generation and variant you intend to buy.
Photograph accessible hardware and compare it with the manufacturer’s diagrams. Do not assume a product for one track shape will fit another because both are described as curtain motors.
Measure the required features
Follow the guide’s specified measurement points. Record units, where each dimension was taken and any uncertainty. An overall rail length does not replace a required cross-section measurement.
Keep existing hardware intact while assessing fit. If measurements require unsafe access or disassembly, obtain appropriate help rather than climbing on furniture or forcing a fitting open.
Check ordinary movement
Confirm the curtain moves normally and note joins, stops, bends or other features relevant to the compatibility guide. A motor should not be expected to repair damaged or binding hardware.
Do not infer a supported curtain weight or track shape from a product photograph. Check the exact product’s limits and ask the manufacturer about an uncertain arrangement.
Count the necessary units
Determine whether the curtain opens from one side or has two independently moving panels. Confirm how many motors, attachments and other components the desired arrangement requires.
A single-unit offer and a complete two-panel bundle are different purchases. Compare what is included, including any separately required hub or charging accessory for the features you want.
Separate fit from remote features
Physical compatibility does not establish remote-away access, voice-platform support or every schedule capability. List the intended functions and verify their hardware and service requirements.
For hypothetical budgeting, two units at an invented $60 each total $120 before accessories or delivery. This illustrates counting; it is not a current price or recommendation.
Keep a pre-purchase record
Record motor generation and variant; track type; required dimensions; curtain arrangement; included parts; desired remote features; return restrictions and unresolved questions.
After installation under the product instructions, verify ordinary travel before adding unattended schedules. Preserve a usable manual arrangement as directed by the manufacturer.
