Have a pair of Aqara Curtain drivers E1 track model see: https://www.jbhifi.co.nz/products/aqara-curtain-driver-e1-track

They work via Zigbee 3.0 and are compatible with Home Assistant (with a ZigBee 3.0 hub) or apple, google or amazon smart home via an Aqara Zigbee Hub.

About 20-months old used them for about 3-4 months before taking them down as they had occasional issues with the curved bottom profile of our U-rail curtain tracks. They are supposed to be used with either flat U-rail or I-rail tracks. The better half isn't keen on replacing our curtain rails so best to sell them.

They come in the original boxes with the adapters needed for I-rails, and are in good condition. They have spent most of the time stored in their boxes, with my spare smart home gear.

$300 for both of them and I'll cover the shipping.
