The application allows you to automatically detect and control your OpenSprinkler irrigation system(s). OpenSprinkler is an open-source Internet web-based sprinkler timer / controller built upon the Arduino platform. Features of the app include: * Easy to understand device status * Quick program modification * Launch ad-hoc or defined programs instantly * Manual mode for convenient testing * Multi-device support * View visual representation of upcoming scheduled programs * View graphical and tabulated representation of log data * View current weather and forecast status for the device location * Change and disable rain delay * Multiple supported languages (Afrikaans, Amharic, Chinese, Czech, Dutch, French, German, Hebrew, Hungarian, Italian, Mongolian, Norwegian, Polish, Portuguese, Slovak, Slovenian, Spanish and more) This application requires you to own an OpenSprinkler that is properly connected to your network. For more information please visit https://opensprinkler.com. You can control your device from outside the local network with proper port forwarding and use of the WAN IP within the application or by using a VPN. For further assistance please visit the forums: https://forums.opensprinkler.com This is open source software: source code for this application can be found at https://github.com/OpenSprinkler/OpenSprinkler-App
Version History • OS 3.4 DC support – set a target PD voltage and see the live PD voltage. • Queue manual actions – add manual runs to a queue so they execute in order (requires controller firmware 2.2.1(4)+). • Simpler Run-Once – one clear confirmation dialog instead of multiple pop-ups. • Overcurrent alert control – new “Clear this alert” action in the status bar. • Custom weather URLs – user-defined wsp now supports both http and https (fix for incorrect protocol, #279). Bug fixes • Postponed zone timer no longer keeps counting down. • Rain delay and sensor events now display correctly in logs. • Program disabled status no longer changes after deleting another program. • Station queue activity correctly includes paused stations. • Corrected key index assignments (#281). • Miscellaneous reliability improvements around station sequencing. 2.4.90 11/01/2025 Added support for multi-day watering levels (using historical water data for programs that run on a regular interval) and weather restrictions Support for current fault detection (overcurrent and undercurrent) Fix 24-hr time not showing in the log and program preview Update the program visualization to a more modern look Several other bug fixes 2.4.86 09/02/2025 Local storage isolation – keys are now namespaced by the app’s path to prevent conflicts when served from different URLs.
