I have a new Boltwood III cloud sensor. I was trying to set it up using the ACP.Boltwood weather server and have it read the 1 line log file.
When that didn't work I posted on the DF forum for Boltwood and Doug and Bob replied that I needed to use the ASCOM Alpaca interface.

My chooser fails to discover the Boltwood. My Clarity III software does find and connect to it without an issue.

I did install the ASCOM BolwoodSafetyMonitorSetup file

In the ASCOM instructions it says to use the telescope chooser. Then discover Alpaca devices.
In the Boltwood III instructions it says use the ObserviongConditions chooser which I have been unable to locate.
