Siri Windows API: Make Windows PC print a document via voice command to Siri HomePod I have a Apple ecosystem in my apartment along with a Windows PC.

I am wondering whether Apple offers making a Windows PC on my WiFi network controllable by my Siri enabled HomePod?

If I could make my PC a HomeKit device, for example, I should in theory, be able to teach Siri to carry out predefined Actions on my Windows PC (for example, printing a page to my printer from my Windows pc)

"Hey Siri, print the page I am browsing on my PC".

Has Apple provided an API for this kind of thing? Or not (yet)? Does anyone know of any other non-Apple ways to do this?  (e.g., something similar to this).
Workflow on iOS allows you to perform web service calls and send commands over SSH. The Siri shortcuts functionality coming in iOS 12 appears to be based at least partially on Workflow’s technology (Apple aqui-hired the developers.)

As to whether all of Workflow’s functionality will appear in Siri Shortcuts at some point, I have no information either way.

Even if it does, it would be up to you to provide some sort of endpoint/plumbing on the Windows side to actually pull this off. You’d be fully on your own.
