This system requires the internet in order to program and manually manipulate the stations. It also provides an ap for using a smart phone to do this work. This will come in handy for troubleshooting a large complex irrigation system such as we have. Replacing the old Toro controllers with Open Sprinkler Pi does ads some cost but does not actually increase work as we are under capacity already and the addition of an upper zone for hedgerow makes work necessary. Open Sprinkler would also unify the controller in a new location under the Barn front porch and will require the addition of new 20 conductor control wires from barn to oven valve location and additionally a 13 conductors from the oven to old hoop house location. This is needed so we have control to the upper orchard area and the lower garden, butterfly garden, chickens, house and fig area. This is a total of 18 stations whereas we now have only 11 of which 5 are down due to the waterline brake last year. Hence it makes since to make this change before summer as work will have to happen anyway, otherwise we risk crop and tree failure such as what happened to the figs last year.
We will need both the basic and the expansion which give us a 24 zone capacity also a new Pi so total of $162 where as the Toros are $70 each. The job will require minor trenching, conduit and wire which will perhaps another $50.
Other possible integrations may be path lighting, landscape pumps and irrigation pumps which will enable future economies.
