Rachio is introducing a new version of its smart sprinkler controller today, with a slight design tweak and a handful of new features. Among those is support for faster 5GHz Wi-Fi — although it’s hard to imagine that this will be terribly useful for a sprinkler system — as well as support for “hyperlocal” weather information so the system can better determine when to water your lawn and physical controls for getting your system to start and stop watering.

Those aren’t major changes, but there’s one addition that is: Rachio is also adding support for a water flow meter, which can be attached to your sprinkler system’s water line to detect leaks and wirelessly relay that info back to the system. If a leak is detected, Rachio can shut down the system so that you don’t waste water or ruin your lawn. Rachio also says the flow meter can be used to more precisely control water usage, which should theoretically lead to more efficient watering.
