Hi Jannis,

Netro sever side gets and updates weather information every early morning at 4 am. Netro gets weather forecast data to adjust watering.  If forecast data is wrong, Netro will adjust accordingly using the historical data. For example, if the forecast data is 10mm for today, but two days later, we got the actual rainfall is 5mm, Netro will adjust schedules and could water more accordingly. 

Thanks,

Netro Support
