FYI, Friday and yesterday were not the best for comparing precipitation. We had sleet on Friday afternoon->night, which currently over-reports on the WeatherFlow due to the sound it makes, and some of it sat in the Davis cone until it warmed up yesterday before being measured. The WeatherFlow logged some false rain yesterday as well, since it is attached to my deck railing and we were doing some construction work with sawing/hammering on the deck. (There's also gaps in the WF data, as a result of my having to shut down the WeeWX computer and move it away from the construction zone.)
WeatherFlow has data scientists working on continuous learning algorithms to make their stations smarter, but still have not rolled out the rainfall code yet that I know of. If rainfall is important to you, I'd recommend using a decent tipping bucket or 4" manual Stratus rain bucket with the WF station.
WF as a company really stands behind their products, and has competent tech/customer support folks. They also publish open API's for multiple ways to access YOUR data for free, unlike the walled gardens set up by other PWS vendors in this price range such as AcuRite and Ambient who will only let their customers share with WU. There is a thriving community of third-party developers with support for the WF station's data, including the WeeWX UDP driver that I developed and freely share.
Although there are some pitfalls to the non-mechanical precipitation measuring technologies used by WF and the optical Hydreon RG-11, they do have the advantage of being able to send a start-of-rain alert upon detecting the first drop. This is useful for home automation folks, as well as people who leave their car windows/roofs open in the driveway. By the time a tipping bucket logs its first spoonful, those leather seats are pretty well soaked.....
