I have a couple sensors that are being read from a csv file. I have been looking for a way to mark them as unavailable under certain conditions. Is that possible or do they always need to have a value?
I haven’t tested it, but you should be able to disable the entity to prevent it from being used and re-enable it after?
Thanks for the tip. That does the job. It would be kind of nice if they didn’t have to be hidden or if it could be automated, but from a logging standpoint disabling it does what I was hoping for.
Have you tried Spook 
a scary powerful toolbox for Home Assistant. - this adds the capability to disable/enable an entity (amongst other things) that you can use in an automation?
