Why might my sensor entity be unavailable

[paddywwoof]

I seem to have set things up OK, in so far as I can see agile times and rates and I can see from the log that TargetTimeframe can see them too. I can't get the relevant entity for displaying on a front page card. Any more info happily given.

I'm not sure why it's unavailable as the logs suggest it's calculating rates fine. I assume you've tried reloading the integration or restarting your ha instance. This shouldn't be required but not sure if HA has got into a weird state.

Dave, as you guessed, as I puzzled out other aspects of my new system, at some point, I noticed that target timeframes could now be referenced as automation triggers and the warnings had disappeared! Presumably as a result of one of my HA restarts.

Thanks for all your work on this, it's really great.
