    GHL settings not restore-able after firmware update

    Any chance we'll see more than 8 dosing times added at some point? More importantly, setting timeframes with dosing amounts?

    I really want to do away with my Apex and move over to Profilux. One of things holding me off (other than time and money lol) is that you can only program 8 times to dose throughout the day. One of the few (but major) benefits that DOS has over Doser 2.1, is that you can set time-frames for...
