Help with photon core, smartthings, and roomba

I’m hoping someone can help.
I saw a thread create by Camden krupala who designed some code for a photon core to integrate with a roomba 880 and also smartthings. He even created a sway presentation that helped walk you through the steps for coding.

I got the code to work for the particle (photon) core but his device type code does not work in the sway presentation anymore.

Has anyone tried this in the past and has the device type ( or I guess device handler) code available?
It’s the last part to get it to integrate with smartthings and have the Roomba part of my smart home.
I have tried to message the original creator but I think he isn’t involved much in the community.

Any help would be amazing.
