If the system is offline, e.g. because the Wi-Fi is switched off or the DSL line is disabled, then the system has an "emergency mode".
It then irrigates without taking into account the weather data, as it has been stored in the schedule per valve.
Before the "emergency mode" starts, the controller first tries to get back online. The offline irrigation does not start immediately, but only after about 5 minutes.
Irrigations that run offline are not being sent to the servers and thus are not displayed in the statistics. Should e.g. the electricity be interrupted, there is no irrigation at all.
