OpenSprinkler Forums OpenSprinkler Unified Firmware Trouble with Zimmerman Method Reply To: Trouble with Zimmerman Method



Hi Feri,

Due to recent changes in Hungarian weather (rain, low temperature) the 0% watering level is the expected result of Zimmerman calculation IMO. I know how cold it is nowadays. I live in Budapest 🙂 I even shut down my opensprinkler and switched on heating instead.
