Zigbee roller shade motor for 37/38mm tubes: check tube diameter, gateway and charging first

This is a battery-powered Zigbee roller shade motor designed for 37mm and 38mm tubes, controlled through Tuya or Smart Life once it is paired with a Zigbee gateway. The important point is the radio: Zigbee is not Wi-Fi, so the motor will not appear in the app with your phone alone — you need a Zigbee hub on the same network, and the pairing step happens through that hub. Because the fit is mechanical, check three things before ordering. First, the exact outside diameter of your roller tube, since 37mm and 38mm are different tubes and the drive adapter is matched to one of them; if your tube is a different size the motor will not grip. Second, the shape of the tube's inner profile, because the drive wheel has to seat in the track the chain mechanism used, and tubes from different shade makers have different profiles. Third, how you will charge the battery and whether you can reach it, since the motor sits inside the tube at the end and you will have to bring a cable to it. Limits are set through the app, so you also need a phone that stays connected during setup. If the page does not state which tube diameters and which inner profile the included adapters cover, ask the seller before buying.
