I actually manage close to 700. The aforementioned ones are only in the recent burn areas.
I will actually write a program for the perimeter for each property that is in prone burn areas.
The program, nor the Rachio controller is intended to be a fire safety nor life safety device.
My program will wet the perimeter of the property to minimize burning of the vegetation.
I set the program to run every hour for short minutes just to keep things moist until the danger has passed.
