It seems to indicate that it does include a manual shutoff, but I haven’t placed the order yet, so I can’t confirm first hand.
I also think that I’ll be leaving the manual shutoffs there inline with this device. While this is a great addition to couple with my water sensors already placed in key locations (water heater, washing machine, kitchen) there is plenty of space, and my existing manual shutoffs are in great shape, so I have no driver to remove them.
In my use case, I will not program any logic to turn the water back on automatically after an incident. I want the opportunity to manually inspect the situation first.
The last use case I have for this is in a rental unit. Timely access is not always easy, and you can’t rely on tenants to always do the right thing. This remote safety feature in case of emergency could save thousands of dollars in damage.
