Hi, I’m progressing with the management of watering my lawn. The easiest solution for me is to set correct watering timing based on Et0, rainfall, … Is to use an excel file that create the http string to send to the controller every day. The string is sent by unix script “curl” or “wget”. The problem is that the controller reply ” error code 16″. The same string copied on a browser works well. What’s happening? Also if excel format the string as URL and I click on it, the controller return me “error 16”
