Hello sifus,
Does anyone here know where can I find a 38mm tube of blinds for my Zemismart Zigbee smart blinds motor? I'm using it for my staircase windows so needs to be of custom size. But I asked around a few blinds companies and they only sell a complete solution, and they don't know their own blinds' inner diamatre.

Been stuck with this issue for quite some time now.

I just ordered the blinds from Zemismart flagship store on Taobao install in the end.
