Recommend a master valve that works with R3?

Looking for recommendations for a master valve to install. just looking for simple way to have water on/off with beginning and end of watering schedule. would love a wireless/battery operated that works with my R3, but wired could work if required. any suggestions?

For non-wired, I suggest looking at Wireless Master valve? - Accessories & Sensors - Rachio Community

For wired, any 24 VAC irrigation valve works (probably some others as long as it is within spec). If I were putting one in my system, it would be the same valves that I currently use.
