That would be a great feature. I currently have a TI 4-switch box that interfaces through the RoboFocus Control Program or Digital Dome Works Control Program. From a remote location, I switch things on manually using the RoboFocus control program and back off when the sequence is done. Usually, though, I’m asleep when it’s done so things stay powered up until the morning.
After my mount, the dome and the camera are switched on, I have to exit the RoboFocus program in order to use ASCOM in SGP then after disconnecting in SGP, bring up the control program again to turn things off. It hasn’t been a problem but would be much better if the switching could be done automatically. I am not aware of an ASCOM interface to the RoboFocus switch box, just the focus control.
