I use the AAG cloudwatcher with SGP - using ASCOM OK to Image device - setting the wind, cloud and rain settings for 'ok' for imaging.
The weatherstick is more of a nice to have - I use it for humidity and pressure information and temp sensing for the focuser (though I could use the temperature reading from my focusing system too)
My roof controller has an independent Hydreon HG11 rain detector and uses the humidity too, along with the AAG cloudwatcher as a safety monitor 'ok to open' . The roof controller works autonomously for safety reasons and if the mount is parked, will shut the roof if it starts raining. My observatory controller will block ASCOM roof commands if the mount is not parked, or it is raining / misty.
At one time, I thought there may be a way to interface the temp/humidity/pressure in real time to the Paramount ProTrack model - but it does not seem to be on the agenda. I will send an email to Baader about the stick- they worked very closely with Per and I would have thought that the many products he was developing with them would be continued.
