When using the websockets API, this is what I get for evt\_strike (evt)

“evt”: [1658169253, 14, 3994, 1]

Anyone know what the additional “1” is at the end? It is not documented in the API documentation.

There also is a “source : enhanced” field which is not documented. I assume that since the data is coming from the weatherflow server and not directly from the Tempest (as in the UDP feed), this indicates that the data is QC’d (validated against other stations in the area). Can anyone confirm this?
