Automate smart curtain bots with dead light switch line

Is there anything I can purchase to automate two smart curtain bots? I have a light switch, that was connected to some light that I removed and no longer use. Can I use a shelly or some sort of smart adapter which uses the cable as a power source to which I programm a workflow (through iobroker or something else?). Everything will be connected to WiFi/Zigbee.

My goal is to use a switch to either open or close the curtains.

Well, I like the Kasa brand of Wifi lights, but you can also get curtains that hook up directly to wifi.
