Does it? I couldn't find any documentation on those features, if you have links to any documentation that doesn't require going through their servers I'd love to see it since I've been looking for something just like that. Everything I have found, even for querying a single devices, requires making a request to swd.weatherflow.com via an internet connection.

EDIT: I was eventually able to find this: https://apidocs.tempestwx.com/reference/tempest-udp-broadcas...

So it is possible to get the data locally, but it seems like they are pretty strongly discouraging its use.
