I haven't got around to doing much with automating my litter-robot yet, but from what I can see after integrating it into node-red there is quite a bit of information that could be used for automation.
Just take care to avoid this... What's the funniest, most unexpected or downright crazy thing that has happened as a result of your home automation? - #9 by brad5
In all seriousness, I bet @brad5 would have some pretty good input on this topic.
As for the robot/cat interface, my cat has used one for years and I will never go back to a regular litter box if I can avoid it. Generally I don't notice much odor because I keep it in the garage. The cat has become quite lazy and doesn't even bother to bury his stuff anymore. So, once in a while he'll leave a big ol' fresh Stanley Steamer in there and I realize how glad I am that I put in a cat door to the garage.
