Builtin longlife lithiumion battery provides reliable, maintenance power for extended operation. Connectivity depends on your WiFi; control the valve up to about 100 meters from the router in open space. Realworld range may be reduced by walls and interference. Remote operation via a mobile app from anywhere; a physical button on the valve allows onsite operation and precise timing control.

Use scenarios: Home garden irrigation: schedule watering from the office or while traveling. Balcony or patio plants: adjust soaking times from your commute without extra fittings. Seasonal protection: quickly shut off irrigation during rain or when you're away. Why it helps: easy to automate regular watering, avoid under or overwatering, and maintain healthy greenery with minimal effort.
