Yep so far number five seems to be the only compelling reason to upgrade for me, and even that has limited use, because the meter has to be installed after the check valve. This means that only the pressurized lines from the check valve to the to the valve control are protected by this feature. The unpressuized zone pipes are potatoes in this case, unless Rachio learns how much each zone consumes and alerts you possible break in your unpressurized lines. Even then it’s only protecting you from watering your curb while that zone is on or possibly a few dead plants and/or a brown lawn.
Much more useful, would be a whole home monitor installed after your main shutoff that could monitor water usage over a longer interval. This could detect the failed water heater, a burst pipe, or more importantly an open faucet/spigot. I recently got a $500 water bill because my 8 y/o failed to turn off a outside spigot in a inconspicuous location during out normally very wet weather. It ran for several days before I realized what was up. Something like this could pay for itself overnight and I would gladly drop several hundred dollars for a solution here.
