The app seems to work fine when there is natural rainfall and the lawns look green. When the stress of the summer arrives, the customers ALWAYS complain that there is not enough water on some zones. The boost feature is not sufficient. there needs to be a way for us to increase the amount of water that is applied without having to make a manual schedule. That would defeat the purpose of using Netro. There needs to be a way for the user to correct the algorithm. The app will say that there should be 80% soil moisture but when I use a moisture meter and take a direct reading the moisture is around 30%.
