I did, but then got side tracked again! But its basically a python script that listens for the UDP packets, pushes them to an MQTT broker, which HA then subscribes to. As I dont have a Tempest yet, it doesn’t support them yet.
There is a custom component for Weatherflow, but currently that also does not support Tempest, although its being worked on: https://community.home-assistant.io/t/weatherflow-smart-weather-station-via-udp/111558/44
The other option is to use @vinceskahan’s UDP listener which does what mine does anyway (I just wanted something to learn Python with, so wrote my own): WeatherFlow UDP listener and MQTT/InfluxDB publisher utility
Hope that helps!
