I also have an ecowitt weather station, bought a separate GW1000 receiver which feeds into weewx (completely local) and home assistant. You can also add in up to 8 extra temp and humidity sensors so I have some of those in different rooms and the green house.

The rain measurement is a tipping seesaw type so strong winds can sometimes cause inaccurate results
