- implemented issues on github
- The System shall sprinkle if the lawn needs water
- The System shall sprinkle in the morning no earlier than configured
- The System shall sprinkle in the evening no later than configured
- The System shall sprinkle as often per day as configured
- The System shall collect rain data from a weather service
- The System shall be able to read weather data from the openweathermap api
- The System shall operate by simply switching on and off a garden pump at appropriate times
- The System shall determine the amount of irrigation needed based on the weather and the configuration data
- An Administrator shall be able to configure the system by setting
- coordinates of the location where the system is operated lon/lat
- l/minute the sprinkler deploys when switched on
- earliest time in the morning the system may sprinkle
- latest time in the evening the system may sprinkle
- number of times per day the system shall sprinkle if needed
- size of area to being sprinkled
- average l/day beeing evaporated per day by non lawn plants (e.g. trees)
- A user shall be able to arm/disarm the system
- A user shell be able to see the system operation log
- The system operation log shall show the amount of water that has been irrigated as an equivalent mm rain / day and the total liters for the area
- The system shall read a list of weather locations from the openweather api
Use cases
configure system
As an administrator I'd like to configure the system.
arm / disarm system
As a user I'd like to arm/disarm the system. When the system is armed it will automatically sprinkle. If the system is disarmed only manual operation of the sprinkler is possible.
