@jreisberg Unfortunately, this doesn't seem to be possible. Several posts mention this problem. Even if you get your position from your GPS on your laptop via the NMEA network, Windy can't use it. A user offered to develop a plugin, but I don't know why it has not been published https://community.windy.com/topic/31066/list-of-finished-windy-plugins-v42/45?_=1734024275855

@jreisberg At this moment, there are no planned changes about this, so it is not possible to add these to Windy.com.
