How can I keep track of the last day so etching happen Ed?

I’m trying to figure out a way to display the last day and time my roombas ran. Anyone know if that’s possible?

First, I’m having a really hard time understanding the title of this thread. I have no idea what you mean by “so etching happen Ed?”

but to your question…

do you have an entity that contains that information as attribute or otherwise) in the states page of HA?
