Are there any aftermarket Hubitat compatible shade control motors that retrofit by hooking onto an existing roller shade string loop? I’ve seen some that connect to a chain loop, but not to a string.
Zemismart Zigbee. They come with 3 fittings, two for bead chains and one for cord. I think for compatibility it’s the AM45 model you want. It’s a bit confusing as there are multiple variations available. After initially getting the wrong model on Amazon UK, I got mine from AliExpress (about £55 delivered I think)
