I guess yes:

But you should imho Ask Kaj from Slide or fe the Developer of the App.
Also check in the Google Sheet list there if YOUR slide is updated to the latest mentioned version.
In older versions you need Digest, and you need the correct local ip of Slide.
Although the Local API is already available the Homey Slide App v2.0.x uses the mdns for discovery and to support dynamic ( cq changing of) IP address for the Slides.
I expect is not to work with the older Firmware Slides.
