I just installed the Home Assistant Baby Buddy integration. In one of my dashboards, I’d like to reference the sensor.[babyName]_last_change
entity to display a line of text like “Last changed X hours ago”.
If I call {{ states('sensor.[babyName]_last_change') }}
, I get a string in this format: 2023-02-02T21:59:00+00:00
.
I thought I might need to use strptime
to parse the string into a datetime
object, but when I look at this documentation for strptime, I can’t seem to figure out what directives to use to account for every bit of the resulting string. For instance, I can account for the 2023-02-02
fairly easily, but I don’t understand the T
that follows it, nor can I figure out how to account for the time zone offset in +00:00
format.
I’m also still very wet behind the ears when it comes to templating, so I might be doing this the very hard way. If you have any tips on how I could more easily take the string output of sensor.[babyName]_last_change
and produce text like “Last changed X hours ago,” I’m all ears!
