Quick specs

Sprung arms hang directly on an existing rod (Rod version) or clip onto a U-rail track (separate U Rail version); supports curtains up to 15 kg (about 33 lb); built-in rechargeable battery lasts roughly 8 months per charge (USB-C to recharge); QuietDrift mode keeps scheduled/automatic movement under about 25dB. Standalone Bluetooth/app control works out of the box; adding a SwitchBot Hub unlocks Alexa, Google Home, SmartThings, and IFTTT — full Apple HomeKit/Matter support specifically needs the SwitchBot Hub 2, not the cheaper Hub Mini.

Who it's designed for

Renters and apartment dwellers who can't install a permanent motorized track or do any rewiring, and who have a standard curtain rod or U-rail track within the 15kg weight limit.

Worth knowing

  • Despite what some marketing copy implies, the sunlight sensor is not built into the Curtain 3 itself on this generation — it lives in the separately-sold Solar Panel 3 accessory, and at last check automatic light-triggered open/close wasn't yet functional even with it installed, just light-level history
  • Full Apple HomeKit/Matter support requires buying the SwitchBot Hub 2 separately (roughly $50–70) — factor that into the real cost if HomeKit matters to you
  • A few users report the Bluetooth-to-Wi-Fi handoff being inconsistent for away-from-home control, occasionally needing an app restart
  • It's a bit chunkier than a fully integrated smart curtain track, which is the tradeoff for a no-tools retrofit

How it compares

  • SwitchBot Curtain 3 vs. a fully integrated motorized track — the SwitchBot is the pick if you rent or don't want to replace your existing curtain hardware; a built-in track is smoother/more integrated but is a bigger install commitment
  • Standalone vs. with SwitchBot Hub 2 — standalone gets you app and schedule control; the Hub 2 is worth the extra cost specifically if you want Alexa/Google/HomeKit voice control

Bottom line

If you want your existing curtains on a schedule (or the QuietDrift gentle-wake feature) without replacing any hardware, the Curtain 3 does exactly that — just budget for the Hub 2 separately if voice-assistant control matters, and don't expect automatic sunlight-triggered close without the separate solar accessory.
