Typical irrigation controller rain sensors, such as what came with my Hunter in The Villages and in other homes I have owned, are maintenance headaches. The reported precipitation from the stations the Rachio looks at is more than accurate enough. While there may be some rain events that are missed or reported and didn't actually occur at my house, on average it will be pretty close.
