By default, StellarMate Pro does not turn off power to devices after an equipment profile is stopped. Once you toggle on/off a 12V DC output, SM Pro remembers this across sessions. However, it is sometimes desirable to turn off power to connected devices as soon as an Ekos equipment profile is stopped. This might be useful in permentant observatories where StellarMate Pro is always powered. To enable this option, turn on the Power Off option in StellarMate App Power tab.
