I'm looking for a way to install some type of smart curtains. However my wife will not let me change the current curtains as she picked them out not that long ago.

We have Round (1") Curtain Rods with Grommet Style curtains that open in the center.

So far my investigation seems to show that the only smart curtains that will work for me is the SwitchBot curtain. It also appears I will also need the switchbot hub, which is unfortunate as I'm getting quite a collection of hubs for various devices (Alexa Echo, ZigBee, Wyze), but realize until the world settles on one standard that's the way it will have to be.

I see from the SwitchBot website that for my type of curtains I will need the "Rod Style" bot with a "Grommet Kit". I can find all the parts I need except this grommet kit! It does not seem to be listed anywhere else on the website or on Amazon. Where can I find this part?
