That’s awesome! The only suggestion I have is renaming it from timeline to it’s actual name? something like water pressure? The only reason I mention it is because the logs first two options represent water timing per station whereas the timeline in your modification seems to do water pressure?
Subsequently, we can make the 3rd tab only appear if a setting is present to show logged pressures. This is done in config.php and basically enables/disables reporting of the data if its available. You could also add options to point to the data if needed.
Let me know what you think though
Update: I just looked through your code, you nailed it! Looks awesome can’t wait until its smoothed out.
