Answer
Based on the search results, there are several promising options for an intelligent, wireless water valve system with smart home integration: Closest Match: True Wireless Valve by Uhome
The True Wireless Valve offers many of the features you're seeking:
Battery-powered (4 AAA batteries lasting up to two years)
Home Assistant compatibility (ZHA and Zigbee2MQTT support)2
Can be integrated with leak detectors
Supports remote monitoring and control
Designed for residential use
Alternative Option: SONOFF Zigbee Smart Water Valve
Another compatible solution with similar features:
Compatible with open-source platforms
Supports integration via ZBDongle-P or ZBDongle-E
Voice control through Alexa and Google Home
20-month battery life
Supports multiple irrigation modes5

Open-Source Software Reference
The Smart Water Management System GitHub project demonstrates an open-source approach to water management, though not exactly matching all your requirements:
Android app interface
Supports water consumption tracking
Uses solenoid valves for control3
Limitations and Considerations
While these solutions come close, they don't fully meet every specification you mentioned:
Mesh network capabilities are not clearly detailed
Web browser control varies by platform
For a fully custom solution, you might need to combine multiple technologies or develop a custom implementation using platforms like ESP32, Home Assistant, and custom power management.
