Thank you Phil for your feedback! The zones showing disabled stations is something other users have echoed and honestly an oversight on my end when incorporating the ability to disable stations. I am fixing this in the next release.
In regard to the rain delay not updating on toggle, is this in regard to scale? I am testing this out on my end and the graph is in fact updating/refreshing when toggling the station. I know this is was a bug previously so just to make sure, are you on the latest current: 1.2.7 (1.2.6 for iOS, still pending app store testing)?
For deleting specific log entries this isn’t possible without removing the SD card and editing the file yourself however Ray does have the option to delete a specific day instead of the entire log history. I will see if I can incorporate that into the app.
