The premium retrofit: rather than clipping onto the outside like a SwitchBot Curtain or Blind Tilt, this motor replaces the internal mechanism, sliding inside the roller tube (38–51mm, or 25–30mm on the smaller-tube variant) so no chain is visible. Eve publishes no maximum fabric weight, only torque — 1.1Nm large-tube, 0.5Nm small — fine for typical UK roller blinds but tight on heavy blackout fabric over wide windows. Fitting means removing the blind and swapping mechanisms, a 15-30 minute job, not a clip-on. At £179.95 it costs roughly double a SwitchBot Curtain for a cleaner, cordless result. Needs a Thread border router such as an HA Connect ZBT-2.
What can Home Assistant control on the Eve MotionBlinds Upgrade Kit for Roller Blinds?
| Control | Type | What it does |
|---|---|---|
| Position | Cover (0-100%) | Set/report blind position via the Matter window-covering cluster; supports open, close, stop, and set-position calls. |
| Battery level | Sensor (%) | Percentage battery remaining — the motor is internally battery-powered, USB-C rechargeable. |
| Battery voltage | Sensor | Raw battery voltage reading alongside the percentage sensor, useful for spotting cells aging faster than the percentage estimate suggests. |
| Firmware version | Sensor | Reports current motor firmware; relevant because pairing reliability and calibration behaviour differ notably between shipping firmware and later OTA updates. |
| Identify | Button | Triggers the motor's identify behaviour to confirm which physical blind an entity corresponds to during setup. |
Home Assistant's Matter integration exposes the standard window-covering cluster, but the motor won't respond to open/close/set-position commands until top and bottom limits are calibrated with the USB power cable attached — calibrating without power connected makes the blind wiggle as if calibrating, but silently discards the position, leaving Home Assistant reporting a fully-open state that doesn't match reality. Initial Thread commissioning has also tripped up early adopters: some units ship on firmware that fails QR-code pairing straight into HA and need a first pairing through the Eve or Google Home app to pull an OTA update before direct HA/Thread commissioning succeeds reliably.
