D-D H2Ocean P4 4-Channel Wifi Dosing Pump

Warning you need to have a split 2.4GHz and 5Ghz router, they can't share the same SSID.The App needs to have all permissions on.The App really needs some polishing. It will do the job but is not intuitive, doesn't validate inputs in the configuration, and any problems are not reported with enough detail for you to diagnose the issue. I am a software developer, so my criticism is from an objective professional perspective - I wouldn't have let this be released into production.That said D-D support were very quick in replying and solved my problems. Great support!2 stars forfeit for the pain of setting it up!
