timonsku, (edited ) E: Ok I think I got a few options now, thanks!
I have a pressure pump that is controlled via WiFi to water my plants at specific times.
That works well but my issue is that I get siphoning for some low standing plants.
I can't find something that would essentially only allow high pressure to flow and stop at low pressure. This could be as simple as a backflow valve with a stronger spring but it doesn't seem to be a thing?
Electric solution also ok but needs to be pressure controlled.
