They just came out with a new model literally this week, so you might look for a used SmartWeather station perhaps. For integrating with HA, you could pick the data off the UDP broadcasts via a program (I wrote one and lots of people use it), you could integrate that with HA pretty easily I think. My python program can broadcast to MQTT that HA could subscribe to, or something like that. I run my listener and HA in Docker containers on a i3 Intel NUC running ubuntu, but a pi3+ or pi4 could easily handle it. One thing I need to mention about the WeatherFlow stations is tht the rain is 'not' generally accurate in realtime, if that matters to you. They have a magic thing called 'rain check' where they apply corrections after the fact and you basically can see the previous day's corrected rain via their website. All the other sensors seem pretty good though. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
